BPG Materials, Equipment, and Tools

From Wiki

Book and Paper Group Wiki > BPG Materials, Equipment, and Tools

This page is designed to be a list of materials, tools, and equipment used in paper and book conservation. For clearly defined (and Google-able) terms like "Scharf-Fix" a word or phrase may suffice, but images are particularly welcome for:

  • modified tools
  • innovative solutions to problems
  • common materials that have been re-purposed for conservation (Gore-tex, trash cans made into humidification chambers)

Also welcome are images that distinguish between similar materials (like Reemay and Hollytex) or link together different names for the same material (soot sponge and dry cleaning sponge).

Captions should be short, ideally less than 25 words. They can include a references link to more reading - either on the wiki or elsewhere. When you click on the photo, it will take you to the file page for that image which can include more detailed description, information about the photo creator, product information, etc.

Gneisinger, Walter and Watkinson, David. “Innovative Uses for Aqueous Foams in Conservation Practice”, Tradition and Innovation: Advances in Conservation. Contributions to the Melbourne Congress, 10-14 October 2000, pp. 77-81.
This paper looks at the use of foams in cleaning and consolidating textiles. The use of foams in conservation has been regarded with suspicion, as not enough analysis has been done on the use and efficiency of using foam instead of water or an adhesive. The advantage of foam is that it they minimize surface tension effects, limiting the amount of water in aqueous treatments, making it a useful tool when cleaning or consolidating fragile porous materials. One of the limitations of cleaning with foam is that the material has to be rinsed after the foam/detergent has been applied.
The authors describe the composition of foam and its benefits, as well as an experiment they conducted where they compared different detergents and methods of cleaning textiles. They did a number of experiments, washing the textiles in water with Synperonic N, Marlipal 013/89, NP 10 and Brij 56 at room temperature, 30oC, 45oC and 90oC, and then using 1000cm3 of foam (with the same detergents) at room temperature. It was concluded that washing textiles with the various detergents at 30oC was still more effective than using 1000cm3 of foam. The authors increased the volume of foam to 3000cm3, and this achieved a similar level of cleaning as a 30 minute wash in water at 30oC.
Though the washing of materials with foam seems like it might not be as effective or practical as aqueous washing, the application of a foam consolidant is a very interesting idea. This could be a good method for consolidating, when a ultrasonic mister cannot be used, for example with very large fragile objects or freshly excavated objects on an archaeological dig.

In 1972, the author invented the suction table and later went on to develop the moisture chamber/suction table/ultrasonic humidifier/air filter system during the 1980's. Kemp’s chamber fits on to a suction table so that an object can be humidified with ultrasonic mist or solvent fumes can be extracted through the air filter system. In the past, other tools had been used to consolidate flaking paint, such as airbrushes, spray guns and the Preservation Pencil. The limitations of these tools are that they are either too strong or that they have a large nozzle so the area covered by the consolidant is too large. The ultrasonic mister in conjunction with the suction table allows for control over the air pressure of the compressor, the amount of ultrasonic mist released by the humidifier, and the force of the suction. This article gives many examples of works of art, with different mediums, that were consolidated under the dome with this method.

In 1990, the Canadian Conservation Institute developed the use of the ultrasonic mister for the treatment of flaking pigment on ethnographic objects, and modified for use in paper conservation. The paper provides a brief overview of the equipment, set-up and application of this technique using the consolidation of a flaking gouache painting Black Sun by Michael Snow as a case study. The technique was successful in treating the flaking gouache paint on paper. CCI's original design consisted of modifying a ultrasonic humidifier so it could create a mist of a dilute consolidant, stored within a bottle. The mister also has a local extraction system incorporated in the hand-piece, which collects excess mist that may otherwise build up on areas adjacent to the treated area. In order to use the CCI’s ultrasonic mister in paper conservation, the design had to be modified. The extractor component of the hand-piece was removed, making it smaller and easy to manipulate. A smaller nozzle replaces the original, directing a very narrow stream of mist. The mister is normally used in conjunction with the suction table, helping to reduce the possibility of a build-up of overspray on the work. The table also helps in the penetration and drying of the solution, reducing the risk of an accumulation of adhesive during treatment.
Pataki, Andrea. “Remoistenable Tissue Preparation and its Practical Aspects”, Restaurator, 2009, pp. 51–69.
This article looks at the adhesives used to prepare remoistenable tissues for repairs. The successful adhesives for light-weight tissue repairs were: Gelatin, isinglass, cellulose ethers, starch paste and synthetic adhesives such as Aquazol® and Paraloid B72. Funori and JunFunori® were tested and showed to be unsuitable to make remoistenable tissues. A successful adhesive was judged based on its ability to form an adhesive film, by the concentration it must be made to, by the flexibility of the tissue-adhesive, by the transparency of the adhesive tissue and by the adhesive’s swelling ability, which enables re-activation. The article also looks at the types of tissues used for repair and their characteristics, as well as looing at the different adhesives in their various concentrations, and how these have an effect on their flexibility and what solvents are needed to reactivate the tissues. These qualities are very important when choosing an adhesive and tissue to make your repairs with. The results are reported in a very clear and easy to read table. Images are used to explain some of the tests that were done, which are also useful to understand the issues or advantages of using certain materials.
Ross, Suzanne and Phenix, Alan. “Vulpex spirit soap as a cleaning agent for painted surfaces”, WAAC Newsletter, 2005, Volume 27 Number 1, pp. 15-22.
This is an article that discusses the benefits and limitations of using Vulpex soap. The manufacturer (Picreator Enterprises Ltd. of London) describes the detergent as“a safe cleaner for practically everything from paper to stone.” It can be diluted in either water or white spirit and is often called a spirit soap, also known as a potassium methylcyclohexyl oleate. Vulpex has a pH of 13, meaning it is strongly alkaline.
The authors explain that they are still unsure what the ingredients of the soap are which is always a problem for conservators because it is important to know what we are applying to the surface of an object. They are also concerned about the detergent possibly leaving a residue on the painting’s surface. GC-MS and XRF analysis resulted with a higher level of potassium residue on the surface of the pigments. Though Vulpex is an effective agent to clean painted surfaces, the detergent can swell oil paint, so conservators are advised to use the detergent with caution as it could lead to undesired effects. By lowering the Vulpex solution, the risks to the oil paint layer are decreased. The solution is usually used at a 1:10 dilution, but it would be recommended to use an even more dilute solution.

Warda, Jeffrey, Brückle, Irene, Bezúr, Anikó and Kushel, Dan. "Analysis of Agarose, Carbopol, and Laponite Gel Poultices in Paper Conservation" Journal of the American Institute for Conservation, 2007, Vol. 46, No. 3, pp. 263-279.
Agarose, Carbopol and Laponite gels were evaluated as alternatives to cellulose ether poultices on paper artifacts. It was concluded that Carbopol and Laponite RD leave residues on paper which lead to discolouration upon ageing. Agarose did not discolour the paper after artificial ageing. A gampi usouyo barrier tissue was used when applying the gels, and showed to not leave any staining upon artificial ageing of the paper. Methylcellulose A4M still shows good ageing properties and should still be used as a poultice. Agarose may leave agaropectin, a non-gelling polysaccharide, on the surface of the paper, which is not ideal as it can be seen as a food source for pests.
