Conservation for the Digital Age

Alex Uhde, Guest Contributor


Editor’s note: The Institute of Archaeology’s Technical Service Manager, Alex Uhde, was presented with the challenge of retrieving and preserving material at risk of being lost, much as we strive to do as conservators. Alex kindly wrote up the technical process and experience for us, as an insight into the possibilities and realities for conservation of modern digitally supported culture, in which the material itself may be less tangibly linked to the information it supports than we are used to.

A member of academic staff presented me with an unreadable USB flash drive and asked me to salvage the data. Although the USB controller was detected by the computer, the data it housed did not appear. This suggested that the odds of data recovery were low, but I continued as the data on the drive was of high importance.

First, I removed the plastic shell of the drive and found nothing of immediate concern at first glance. On closer inspection, I found a small spot of corrosion connecting two pins on the flash memory chip. This I removed with the tip of my screwdriver, and then connected the drive again, only to receive the same unsuccessful result.

At this point, I decided that there were only two likely remaining possibilities: complete failure of the flash memory chip (or a portion of the circuit connecting it to the controller), or a cold/cracked solder joint.

I made several more attempts to connect the drive, and on one attempt I did get the LED to flash and the name of the drive – though none of its contents – to show up. This occurred whilst tightly squeezing the flash memory chip. I could not replicate this in additional attempts, but it allowed me to have confidence that all components were functional and there was a solder problem.

Based on this, I decided to attempt a risky, and usually temporary, repair known as a ‘reflow’ to retrieve the data from the drive. This repair involves heating the board to a high temperature to slightly melt the solder and fix any broken or cracked connections. We do not have a heat gun in the IT office, so I set out to search the building for one. Dean Sully from the Conservation Lab kindly agreed not only to the use of a heat gun, but to perform the reflow himself. I explained the principle of the reflow process and the desired result.

Dean heated the board until some of the printing and surface coatings started to burn off. Paying especially close attention to the two sets of connecting pins on the flash memory chip, I used a glass bristle brush to gently remove excess soot and debris from around the most sensitive connections before connecting the drive to a computer. Unlike in previous attempts, it was instantly recognised and the data could be fully recovered from the drive. The drive operated as normal.

A copy was taken of the data, as the repair is not expected to last long term due to the on-going presence of the underlying causes of failure and the removal of the drive’s protective coatings. The data, however, was successfully preserved and the drive, sans casing, returned to the owner.


When Heritage Mending Meets DIY Repair

If your office chair is broken, will you repair it or throw it away?

Repair Cafe 1

Last month, some of the MSc 1 Conservation students joined the UCL Repair Café project to advocate repairing and reusing what we already own. Choosing to repair damaged everyday objects is not only fun and environmentally friendly but also reclaims the memories associated with them. Let’s be honest, who hasn’t got a priceless treasure that others may see as meaningless and useless? It might be a childhood memento, an ornament made and given by a friend, or a charm that you’re certain brings you luck. It is the stories behind the objects that connect us to them.

As conservators, we just broadly love objects. Their associations with people, society, events, and ideas attract us and are significant to us when making decisions about repair. By mending the objects, we aim to recover both their functional and emotional values, even as we write ourselves into their biographies. Different from purely functional DIY repair, however, heritage mending requires carefully considering relationships, sometimes at the price of sacrificing functionality.

For the Repair Café, we created a scene of “Theatre of Conservation”. Fully equipped with white lab coats, goggles, gloves, masks, and mysterious analytical instruments, we presented ourselves as the wizards of heritage, offering to share our secrets with Muggles. Two chairs were set up for distinguishing “professional heritage repair” from “hasty DIY repair.” Another two chairs were on the stage in order to give the public the chance to experiment with our analytical instruments and to understand the ways that conservators assess the condition and significance of objects.

Letting everyone know we mean business.

From the conversations we had, it seemed there was awareness of the benefits of repair and reuse for the environment and curiosity in the difference between conservation and DIY repairs. People showed particular interest in getting to practice conservation techniques themselves under our supervision.

This was just the beginning. In the future, we are going to organize more events to share our enthusiasm for objects and showcase the professional skills of heritage mending. Many people signed up to our contact list, expressing interest in attending our future events to learn ways that conservators undertake heritage mending.

What is your impression of conservators? Scientists who can deal with complicated chemistry problems or artists who are able to understand history and society? We are proud of being both. Want to step into the magical world of conservation? Come and join us!

Teach us something, please…

Welcome, from the 2017-2018 MSc1 Conservation team!

We’re a small team this year — there are only seven of us — and we’ve already formed a very close-knit group. We have an advantage over larger teams from previous years: there’s more space in the lab, and it’s easy to bond with such a small number of people. Within a month, we’d  already built a strong sense of community.

Building a cohesive team can be tough, especially if you have a large number of people or clashing personalities. Who really likes ‘team building’ exercises anyway? For our group, team building happened organically when we stumbled upon a subject that transcended our various ages, interests, and backgrounds: Harry Potter.

Leviosa not Leviosar

(Disclaimer: this is not something we learn in the conservation programme.)

We found that we could communicate more effectively with each other once we determined our Hogwarts houses. Eventually this led to the printing of house banners and designation of Moaning Myrtle’s toilet in the lab office (because the occasional breakdown is inevitable).

Crying Cupboard

“I’m sorry, you cannot access the computer at this time; Brooke is having a minor meltdown. Please try again in 15 minutes.”

We’re also lucky to have brilliant, dynamic professors and teaching assistants that are willing to play along, and our Hogwarts staff is nearly complete. I say ‘nearly complete’, because we’re still waiting on official word from the Sorting Hat on the designation of Dean and Renata. We take this very seriously.


Of course, not everything we do is related to Harry Potter. Our first few weeks have been filled with learning the basics — everything from holding a scalpel to the definition of ‘dirt’ (a several-hour-long lecture on ‘dirt’, mind you). We’ve been settling into the lab as well. Each of us has our own workstation that we can make our own.


Each workspace fits two people, and everyone has their
own microscope, magnifying lamp, and fume extractor.

At first, the only distinction between the workstations was the presence of our Hogwarts house banners.

House Banners

Banners created by yours truly (50 points to Ravenclaw).
(Editors note: While she does try to remain objective, the editor agrees with this allocation of points. Go Ravenclaw!)

 We’re learning conservation techniques by practicing on surrogate modern materials that we have more confidence with. For example, we learned to use a scalpel and tweezers to take samples from an object by practicing on personal items from Caitlin’s office.

Sampling Practice

A selection of Caitlin’s objects to use for practice sampling.

Some of us grew more attached to these objects than others.

Brooke's Boyfriend

Witnesses claim Brooke has been caught repeatedly with Caitlin’s wooden dragon.

We’ve also gaining familiarity with adhesives that we’ll be using or encountering in our careers. We started by taking a ceramic tile and applying sample strips of different adhesives to the surface. This allowed us to experience what it’s like to apply these adhesives when wet, and to see what the adhesives look and feel like when dry.

We can also view the adhesive tiles under ultraviolet (UV) light to see how the adhesives fluoresce. That’s kind of like magic, right?

UV Adhesives


On Fridays we’re surveying and conserving 19th century plaster casts at the UCL Pathology Collection at the Royal Free Hospital. (Editor’s note: stay tuned for a future post by the leaders of the project on how we created and implemented our survey.) Afterwards we head to the nearest pub, The George, for some tipples. No butterbeer here, but they do offer some boozy hot chocolate.

…where Yuhsin met a pug equally excited for Friday.

Be sure to check back for updates on objects we’re working on in the lab and pod projects we’re managing out in the real world. We might share the progression of the lab into our own miniature Hogwarts as well. I suspect the lab will be looking even more cheerful after one of the houses wins the House Cup. Once the results are in, we’ll be sure to send you an owl.

Who’s Your Daddy?

Samantha Jovanovic

Or rather, who is Kyle’s Daddy? We don’t know.

The finished product!


There is the perception that conservation is reserved for ancient museum artefacts, but the truth is, conservation is done on a wide range of objects, including modern ones. For my high-fired ceramic project, I worked on a modern, rather mundane-looking coffee mug. It was probably made in a factory somewhere with millions of other coffee mugs just like it. This coffee mug ended up being decorated specifically to commemorate someone’s first Father’s Day.

The mug as it was received.

At some point the mug was damaged and made its way to the UCL IoA conservation lab. As a student interested in taking on more complex projects later in the year, I chose this mug to start on. Another thing about conservation: you cannot necessarily tell how long a project will take until you start. Some objects that look complicated, end up being a breeze, and then there are objects that are deceptively simple-looking. This mug ended up being the latter.

There are times when an object does not have an owner or caretaker—a person that makes decisions on its care. Much of what is done by a conservator is based on the what the owner of the object wants done to it. So what happens when an object doesn’t have anybody? Well, you do the best you can. I had many discussions with Dean, the course coordinator for the MSc programme, about what would be best for the object and me, as a conservation student. As most of the pieces were available, it was decided that cleaning and reconstruction would be the best route. While I endeavoured to maintain some of the ‘evidence of use’, it didn’t always turn out the way we had anticipated.

The mug was very, very dirty; with soiling embedded deep into the ceramic substrate. Cleaning the mug took months of soaking and many runs under the steam cleaner to pull all of the soiling through the ceramic. It turned into a particularly arduous task. By the time I put it back together, I actually had not realized how successful I was in the cleaning. Before, all the fragments were different shades of brown, and now that are a continuous shade of light beige or off-white.

On a personal note, one of the reasons I chose this mug is because a few years ago I made a Father’s Day mug for my dad. Obviously, I was much older than Kyle when I made my mug, but the decoration is similar. I applied hand prints that look like they are cradling the mug in my hands and I put a similar “I ❤ DAD” motif.

Chedworth Roman Villa

Katie Cook

Term three in the conservation lab started off with an expedition outside of its familiar rooms. On April 26, the UCL MSc Year 1 students made their annual visit to the Chedworth Roman Villa. The villa is one of the largest Roman villas in Britain and is currently managed by the National Trust. The day began with a brief tour of the site, led by Lauren, which provided an overview of the site and some idea of the work that goes into maintaining it during the year and the issues that crop up.

Picture 1

The introductory tour, talking about covering pilae to protect them during the winter.

Although the forecast looked a bit dreary in the morning, the day certainly had its lovely bits. The villa is situated in a sheltered area where it looks out over the River Coln in the Cotswalds. Although Chedworth villa is prominent for its discovery by the Victorians, its preservation and its status as a National Trust property, it is only one of some 50 villas in the area.

Picture 2

A look out over the view from the villa.

The villa has had a very interesting history, as it was uncovered nearly 150 years ago by the Victorians, who did their own work on the site to help preserve it and make it accessible to visitors. Their reconstruction and preservation efforts can still be seen around the site today, including the building that today houses the museum.

Picture 3

Chedworth Villa is best known for its beautiful mosaics, which can be seen in the triclinium, West Bath House, North Bath House and corridor (also known as the ambulatorium). Unfortunately, such treasures also come with preservation challenges. One of which is the fact that all the mosaics save for that in the corridor are built on pilae, i.e. small columns, that support the floor and allow for a hypocaust system beneath it. A fire would be set at the entrance to this system, and the heat would run under the spaces to heat the rooms and floor. However, deterioration of this system over time has also caused some loss due to collapsed floors.

Picture 4

Picture 5

The mosaic corridor or ambulatorium.

UCL conservation students have been making annual visits to Chedworth Roman villa for many years in order to help manage the unique environmental situation that impacts the mosaic floors. The villa is situated slightly downhill from a natural spring, which causes a lot of moisture to be present in the soil. Because the mosaics are situated on the ground in some areas, as in the long corridor, they also take up salts from the ground. If the rooms become too wet, microbiological growth appears, causing damage to the surface of the stones and walls, but when they are too dry the salts crystallize out of the mosaics, also causing damage.

Over the years improved shelter buildings and the introduction of drains and conservation-grade environmental controls have helped to regulate the environment around the mosaics, thanks to an HLF-funded project. A UV eradication program has also been implemented to control microbiological growth on the mosaics. Some areas, however, still need to have heavy growth removed manually so that this system can be used.

And that is where this year’s UCL students came in. Aside from assessing the condition of the main mosaics and rooms in the villa, students tackled the removal of heavy microbiological growth in the North Bath House. Plant growth causes deterioration due to the creep of their anchoring systems beneath the surfaces of mortar and tiles, which then pop off as the plants grow larger.

Picture 6

Because the UV removal system is only effective when the plant and microbiological growth is thin enough to be eradicated, removing and thinning out thick growth by hand is necessary before it can be implemented in the North Bath House. With the use of brushes, scalpels, and various hand tools, students tackled the thick patches of greenery.

Although it is task that takes more than a day to complete, we nevertheless managed to make a dent in the green growth in the North Bath House, which in turn will help keep the stones and mortar intact until further cleaning. In the end, this will allow future visitors, like you, to be able to appreciate these remarkable Roman finds in the depths of the Cotswolds.

Making the Invisible Visible

Katie Cook

Archaeological objects can be fascinating and beautiful artworks all on their own. Think of the Venus de Milo or the Winged Victory of Samothrace, renowned for their beauty despite the fact that both are incomplete. The really important bits of archaeology, however, are the small everyday objects that inform us about the lives of people: the pottery, the remnants of meals, the waste from the production of various crafts. These objects are valuable when they have context, that is information about precisely where they came from within the geography and time line of a site.

Recently, I was working on an archaeological ceramic, a large body sherd from a storage jar found at Tell Jemmeh in Palestine (EXXXVI.49/75), which had lost its context. Without context, this piece of pottery had lost its ability to inform archaeologists about production, decoration, vessel shape and origins of the object within its site, as it could have come from any place within it and any time period.


The whole (section) of the storage jar EXXXVI.49/75, pre-treatment

While cleaning, though, I noticed traces of blue writing, which is readily observable on many other Petrie objects which were marked in the field with their context information. Doesn’t look like much to start with, though, does it?


Having the context information would be very helpful, though! So I undertook a series of imaging tests in order to try and make the faint traces visible enough to read. My first attempt was to examine the object under ultraviolet (UV) light. If it fluoresced, that would make it much more apparent. Unfortunately, it didn’t. While the traces did darken under infrared (IR) light, that wasn’t enough to make it readable, either.

My next attempt was to delve into photoshopping high quality images to manipulate the writing into visibility. And that worked! To one extent or another. I came up with a few final images using a variety of techniques:


Stuart Laidlaw, one of the photographers at the IoA, kindly tried his hand at bringing the writing up as well, and had a bit more success in keeping the colour visible than I did:


Luckily, though faint, it is just enough to make out what looks like HK 180, a context number that Rachael Sparks, the Keeper of Collections at UCL for the Petrie Palestinian Collection, was able to confirm as a viable context number for the site of Tell Jemmeh. It looks like the pot has a context after all, which makes it a far more valuable research tool!

An Update from the Working World

In addition to the current students in the MSc program, some past students occasionally have a chance to update us on how things are proceeding as they move on to their careers in the wider world of conservation.

Anna Funke (MSc 2014-2016)

I am from the UCL conservation class of 2016 and am now taking the first steps as a fully-fledged conservator.

After having lived in London for seven years, I decided that I wanted to go back to the States. So during my internship year, I applied to a wide variety of internships and fellowships all over the US, so that I would have a place to go after handing in my dissertation in September.

In the end, I did the Materials Research internship with the National Centre for Preservation Technology and Training (NCPTT) based in Natchitoches, Louisiana. The centre is part of the National Parks Service and runs a wide variety of scientific studies related to the preservation of North American heritage. I was originally supposed to be here for ten weeks but will now be staying for a little longer, which gives me time to get involved with more projects as well as elaborate on my original research.



Anna in front of NCPTT


While here, I have been running a study on the use of chelating agents to remove iron stains from marble. This has always been a challenging treatment because the acidity of the chelating agent will cause damage to the calcium carbonate in the marble, which can lead to etching. The aim of this study has been to gather data on the damage done to marble by the use of chelating agents, which could then be combined with data on their effectiveness at stain removal. Five different chelators were tested both at pH 9.2 and pH 10. Based on this combined data, the tested treatment solutions could be ranked according to their effects both on the marble and the staining.



Anna cleaning samples after treatment, unstained samples, and stained samples


Now that I have completed the data collected on this project, I will get involved with a study on the effectiveness of different glazing agents in the preservation of historic windows. For this I will be testing the durability of different products using a freeze-thaw chamber.

While I have been here, I have learned how to operate and interpret the data from a wide variety of scientific instruments available to conservation, as well as how to effectively design and run a study in materials testing. It has been a great way of learning more about material science and conservation research.

It has also been interesting working for an organization that is very focused on conservation communications. I have written several blog posts, given a lecture and recorded a podcast in the short time that I have been here. Finally, it has also provided me with an interesting research project, which I can now publish and present at conferences, which will hopefully help me further in meeting people throughout conservation.

Introducing: the MSc year ones, 2016/2017

Clare Lim

Another year, another batch of MSc year one students!


There are twelve of us this year. We come from Canada, Colombia, Singapore, the UK, and the United States. Our academic backgrounds range from archaeology and chemistry to fine art and biblical studies. For some of us, it hasn’t been so long since we were undergrads, while some of us have had several years of work experience in different fields. But what we are very happy to have in common is a great interest in conservation.


This year, we will be very busy with lectures, seminars, research projects, lab work, and extra projects.

During lectures, which are delivered by our course coordinators and guest lecturers, we learn about the materials that many objects are made of, and how they are usually conserved. In lab skills sessions, we learn more about specific conservation techniques.

We will spend much of our time in the lab working on interventive treatments. Each of us will treat at least ten objects during the year. We have the privilege of working on objects from various collections, including those of the Petrie Museum of Egyptian Archaeology. For each round of object allocations, we get to choose from a selected range of objects. (If more than one person wants the same object, the conflict is settled by very civilised rounds of rock-paper-scissors.) While each object allocated does mean adding another task to a growing list of deadlines, it’s still always exciting to have the opportunity to work on and learn about interesting objects.

Hard at work in the lab

We have access to several analytical techniques at the UCL Institute of Archaeology (IoA), including, but not limited to, Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and portable X-ray fluorescence spectrometry (pXRF). We use these analytical techniques in our research projects. They are also useful for helping us to find out more about our allocated objects, so that we can make informed conservation decisions.

Not everything takes place just within the walls of the IoA. We also get to go on trips outside the lab. Click here to read about our fieldwork on Hinemihi, a Maori meeting house, at Clandon Park!

These are just some of the things we will do in our first year in the MSc in Conservation for Archaeology and Museums. Stay tuned for more, and keep an eye on our Facebook page, Twitter and Instagram too!

How is magic done in the lab?

Adriana Paez

Have you ever seen Ratatouille, the 2007 movie by Pixar about the friendship between a rat and a garbage boy, told in a captivating story about food, solidarity, and the pursuit of happiness and perfection sought after in French haute cuisine? Well, as conservators we have a lot in common with chefs. Let me tell you why, and I promise not to be too cheesy!

ratatouille-picScene “Keep your station clean”, Ratatouille, 2007. Youtube

We spend a lot of time in the lab during the first year of the MSc in Conservation at UCL – at least 729 hours, 63% more “classroom” time if compared to the average timetable of a MSc student in the Institute of Archaeology of 264 hours. This situation inevitably changes our perception of what we are doing, strengthens the bonds among the group, increases shared moments around a cuppa or a coffee (I’m Colombian), and transforms the lab into our second home, as one of the strongest identity references for the students of conservation.

Katie, author of our first Hinemihi blog post (see here), once posted a very illustrative picture on Facebook with a caption that read “I’m not saying our lab is dangerous … But we do have more warning triangles than most other doors.” The lab is a space of learning where you need to balance rigorous behaviour and sets of instructions with great doses of creativity and experimentation, just as in a professional kitchen. Like medieval alchemists, we pursue the elusive goal of “transforming lead into gold” with conservation treatments, i.e. reshaping decay into glory through the assessment of the significance or values that must be preserved.

warning-trianglesOur “warning triangles” at the lab door.

How does this happen precisely? Every few weeks pick up an object that embodies an inspiring set of problems. Objects are allocated to us and a precious exchange occurs: each of them allows us to discover how it has survived the ravages of time, and through its materiality allows us to learn about the chemistry of decay and about conservation materials. We can grasp an idea of the values that have saved it from being discarded in this time in which things are constantly being disposed of and renewed. In exchange, conservators devote precious time and skill to investigating them, removing layers of dust, looking into their damage, sometimes identifying previous conservation treatments, and so we apply our best knowledge to transform them, letting them have a new life afterwards.

As in haute cuisine, such a double-edged deal is rooted in a deep connection and understanding of the objects, giving a formal result that can be evaluated according to the highest standards of academia and owner’s satisfaction – or food critics and customers, depending on the case. And just as in haute cuisine, there is a synchrony between time and energy that cannot be wasted, roles and responsibilities necessitating order, cleanliness, high quality supplies (thankfully, we don’t need to haggle with a provider to have fresh products), cutting and heating tools, and working at individual stations to finally produce results as a group.

Last but not least, there is a scene in the movie that reminds me of one of my most beloved aspects of conservation. In this scene, Colette tells Linguini: “People think that haute cuisine must be snooty, so chefs also must be snooty. But that is not so… we are artists. Pirates who can cook, aren’t we?” And the same thing happens in our profession. Every fortnight, some of the students present to the rest of the group her journey in the conservation world (yes, here conservation also remains predominantly a female-led career, taught mainly by men… but this is another story!). And it is mesmerising to know how diverse and enriching our paths are as we strive to become professional conservators, embracing the possibilities for the future.

So, in a nutshell, here’s where everything begins!

Keep your eyes peeled for more stories from the lab, coming soon!

Caring for Hinemihi

Katie Cook

On October 13, the new intake of MSc conservation students undertook their first field work expedition to work on Hinemihi at Clandon Park.

Hinemihi is a wharenui, or Maori meeting house, built in 1880 in Te Wairoa, on the North Island of New Zealand by Ngati Hinemihi people.  Following the devastating eruption of Mount Tarawera in 1866, Hinemihi was purchased by the fourth Earl of Onslow, and relocated to the gardens of his home at Clandon Park in England, now managed by the National Trust. In 2015, Hinemihi experienced another devastating event with the fire that destroyed the Palladian Mansion at Clandon Park.

Hinemihi at Clandon Park nowadays.

Fortunately, Hinemihi was left undamaged by the fire, and this MSc student fieldwork is part of an ongoing effort to maintain Hinemihi as a living building. Our work was guided by Maori protocol, supported by Te Maru Vice-Chair Sam Callaghan, and within the conservation protocols of the National Trust.  On this outing students carefully removed microbiological growth (MBG – lichen & algae) from the exterior carvings of Hinemihi in preparation for the winter cold. Since Hinemihi is outdoors, MBG can retain water and increase the damage caused by frost when the temperature rises and falls during the winter months. It doesn’t hurt that removing green and grey growth from the carvings allows Hinemihi’s beauty to shine through as well!

Setting up.jpg

Getting set up for the day!

In order to carefully remove MBG without damaging the carvings or removing the flaking paint, students used a variety of tools: scalpels, bamboo skewers, dental tools, cotton swabs and deionised water and brushes.


It was a bit crowded since we could only reach so much of the outermost carvings without a ladder.

Although we didn’t have time (or ladders) to reach every surface, Hinemihi certainly looked better when we left and the conservation students will certainly be visiting again to help care for Hinemihi. Look out for upcoming blog posts on the subject!


Before and after: With less lichen and algae, Hinemihi should endure the winter weather much better.
