Conservation Treatment of a Hand-Drawn Map of Sarnia, Ontario, 1848

A watermark from the notable papermaker J Whatman is visible in transmitted light. The map is drawn on hand-made laid rag paper.

Archival materials see some of the hardest use and wear of all paper objects, because their original purpose was usually utilitarian. Sometimes ephemeral, often consulted, maps are no exception. The maps that come in to Book and Paper Conservation Services for treatment show damages typical of handling and haphazard storage, such as tears, breaks, creases, soiling, and evidence of previous restoration as owners have performed DIY repairs in order to return functionality to an item in frequent use.

1848 Map of Sarnia, Ontario, Canada. Before conservation treatment, the map suffers surface dirt, tears and losses, as well as previous repairs with damaging adhesive tape on the verso.

An 1848 map of the town of Sarnia, Ontario that we conserved last year is a perfect example. The map, now part of the collections of the Lambton County Archives, shows several streets close to the shore of the St. Clair River, with specific lots carefully laid out and numbered and buildings and geological features marked.

The map is an original, and has been hand drawn with pen and ink, with roads and waterways highlighted in watercolour. It’s a utilitarian, yet beautiful object, with elegant penmanship and a green silk ribbon folded and sewn around the perimeter of the paper. It may be a thoughtfully designed piece, but it was meant foremost to convey information, and the handling and use it has seen are evident in the damages it now presents.

Lambton County Archives brought the map in for conservation treatment in order to preserve a delicate piece of Sarnia’s history, and make it safe for researchers to access and study.

The map suffered a variety of condition and damage issues caused by use and age, dating from it’s lifetime before entering the Archives. A heavy layer of surface dirt, tears and losses, and adhesive tape residue on the verso were present and needed to be addressed. After thorough condition reporting and photo-documentation, an essential step in all our conservation projects, the treatment began.

Surface cleaning using a smoke sponge is a slow and tedious process, but one which in this case yielded dramatic results. The time lapse images of the cleaning show the grime coming off section by section, brightening the paper beneath.

Next, the remains of the repair tape applied by a well-intentioned soul was addressed. The tape carrier had long since flaked off, but the adhesive residue remained, brittle and yellowed and crosslinking with the paper fibres on a microscopic level. Some solvent tests revealed a match, and by careful swab application, over suction to draw out the dissolved residue, we were successful in removing the disfiguring material. Luckily there was not much staining left in the paper after this was removed, and more stable repairs could now be applied.

In keeping with conservation aims and ethics, a new, stable and reversible repair method was chosen, that of Japanese tissue adhered with wheat starch paste. Wheat starch paste is a clear, strong and flexible adhesive that will not fail, discolour or become brittle with time. It is used by paper conservators to attach thin strips of handmade Japanese tissue to paper objects, to repair tears and breaks. The long-fibred, acid-free tissue holds together the breaks and can be selected to match the colour and thickness of the artifact, being nearly invisible after application so that it won’t disturb the aesthetics of a piece. These repairs were performed on the verso of the map, and fills were added to the losses with a similar process, completing the repair of the mechanical damages on the map.

After conservation treatment, the map is clean and stable.

After treatment the map is bright and clean, the damages are repaired and damaging materials have been removed so as not to cause further long-term deterioration. Conservation treatment has restored stability and aesthetic integrity to the map.

It was returned to Lambton County Archives as good as new, and is now kept in their newly renovated storage facility, ready to serve researchers interested in Sarnia’s early history. Please visit the Archives in person or online to learn more about their collections and the preservation strategies they undertake for artifacts in their care.

Bringing the Past to Life: Conservation & Preservation of Historical Family Documents

Tape removal is executed using solvents during the conservation treatment of a client’s family tree.

The most common paper artifacts that ordinary people save and collect are documents related to their personal family history. Photographs, love letters, marriage and birth certificates that have been passed on from grandparents and great-grandparents are carefully - or not so carefully - saved in albums and drawers of personal mementos. Our ancestors may not have been able to protect them as well as we might wish, and whether through disaster, neglect or simply inherent vice, paper remnants of a family’s history often end up damaged and deteriorated.

Maybe you’re engaged in researching your family’s genealogy. Maybe you want to pass on some treasured items to your children or grandchildren. Maybe you’re simply curious or sentimental about an item that belonged to your great-grandparents. Either way, a conservator can help you restore and preserve these important personal items.

Our studio regularly treats family documents needing repair and restoration. We clean, flatten, repair tears, remove stains, deacidify, and fill and inpaint losses. We offer advice on proper storage conditions to preserve artifacts going forward, and can provide archival housings such as acid-free folders, mylar encapsulation and clamshell boxes for books and bibles.

Previous repairs with tape and bandaids have stained the paper fibres.

This birth certificate, from a family of Polish ancestry, was recently brought in for conservation treatment. The document, over 100 years old, had been stored folded and the brittle paper had broken along the fold lines. It had been repaired in the past with materials close to hand, specifically sellotape and the unusual solution of band-aids! The owner was hesitant even to open the folded document, and consequently couldn’t access the information written inside, the birth and christening dates of her grandmother.

Removing various tapes from the document with scalpel and solvent.

Treatment included humidifying and unfolding the tightly folded package, removing the pressure sensitive adhesive tape and the remaining adhesive residue, and lining the fragments onto a new backing paper in order to create a new full sheet to stabilize the document. Some panels of the document were missing, but luckily the areas with handwritten text were all intact and the client could finally read the information.

Ancestor photographs often come in for conservation treatment as well. Restoring treasured heirlooms is one of the most satisfying tasks of our daily work, and the feeling of returning a revived photograph to the descendent of it’s owner is wonderful validation for our hard work. The photograph below was the only image one client had of her great-grandmother, but biological damage had affected the emulsion layer of the photograph. Careful stabilization and inpainting restored the image, and the client was pleased to frame it with museum quality materials for display in her home.

This small notebook belonged to another client’s Polish father, and was brought with him when he immigrated to Canada after serving in the second world war. Her family now happily considers themselves Canadian, but memories of their father’s war experiences are treasured and revered, and this diary serves as a powerful reminder of the struggles he went though to reach safety. Conservation treatment stabilized it and a collection of other documents related to her parent’s immigration, now preserved for the family’s future.

A charming item came into the studio just before Christmas this year - a client’s childhood letter to Santa. We’re guessing it was c.1970s, by the request for bellbottoms, and the thoughtful request for a mink coat for her mother is very heartwarming. The letter had great sentimental value for the client, and we were pleased to return it carefully restored as a “christmas miracle” in time for the holidays.

Family history documents are one of our specialities at Book and Paper Conservation Services, and we don’t consider any items too small to be deserving of careful conservation and restoration. The stories that come with these artifacts make the work worthwhile, and although the documents may not be of much monetary value, the sentimental worth is incalculable.

Art Conservator and Book and Paper Conservation Services owner Jennifer Robertson recently spoke to the Ontario Genealogical Society about preservation and conservation of family history documents. The talk was recorded and is available for viewing here. If you are interested in learning more about genealogy and connecting with other passionate family researchers in the London area, the OGS’s Middlesex branch website provides information on their monthly meetings and talks.

This small bible (before conservation treatment), travelled with a client’s father while he was on active duty in WWI. The restoration filled losses and stabilized the book, which was then passed on to her son as a family heirloom.

If you are interested in having restoration work done on your family documents or simply have questions on repair or preservation options, don’t hesitate to get in touch. Or, view our portfolio of conservation treatments of Archival Materials for more examples of this type of work.

May your artifacts live safely for many years to come!

Choosing a Conservator: The Canadian Association of Professional Conservators Can Help

Conserving a 19th century photograph album.

If you are considering having an artwork or document restored, whether it is a valuable collection piece or a sentimental memento, it's important to choose a properly trained professional to undertake the work. 

Art conservation is a highly skilled and specialized profession which aims to preserve and restore cultural objects. Conservators examine, research, clean and repair artworks, while also taking action to prevent future deterioration. A trained and experienced conservator will also adhere to a set of ethical work standards designed to protect artworks and owners from damage or misrepresentation. 

But how can you find an art conservator with the right training and skills ? The Canadian Association of Professional Conservators (CAPC) can help.

The Canadian Association of Professional Conservators (CAPC) is a non-profit corporation established in 1971 with the aim of raising the standards of competence, integrity, and ethics in conservation in Canada. CAPC has established criteria and a peer-review process for the accreditation of conservators and conservation scientists and maintains a list of practitioners accredited through the organization. Membership in CAPC is voluntary and it does not represent all qualified conservators working in Canada, however if you want to engage the services of a professional art conservator, the CAPC directory is a good place to start.

CAPC accredited conservators have:

• a high level of knowledge and skill in their specific areas of specialization.

• extensive and varied experiences in their field.

• a formal commitment to abide by the Code of Ethics and Guidance for Practice of the Canadian Association for the Conservation of Cultural Property and of the Canadian Association of Professional Conservators.

The directory lists art conservators accredited by the organization, and is searchable by name, province, and speciality (such as works on paper, objects, or paintings). A short biography and credentials are included for each conservator, as well as contact information.
