Don’t Wash … Scour!

Last summer I recorded my investigations into replicating early 19th century book cloth  using XSL pigments. One difficulty was achieving an even coloring, and several commenters indicated I should scour the fabric, rather than just wash it. Finally, I had a little time to try this, and although I haven’t had a chance to do more dying, tests with wheat starch paste have been astounding.

Note all the yellowish junk that came out of the muslin: oils, waxes, and pectic substances.

I boiled 1.5 yards of Springs Creative 45″ unbleached muslin (133 x 72 thread count, .007″ thick, $4.00 a yard) for two hours in a stainless steel pot, using 1 tablespoon of soda ash per 6 cups of water. Since it smells a bit, it is advisable to have a externally vented exhaust hood.  A long stirring stick is necessary, as are rubber gloves.

Keep a close eye on the boiling muslin. I used large pieces of cloth, for future use as covering material. As the water boils, hot areas form bubbles under folded and wrinkled areas. Then when you stir, they get released and the pot bubbles over, or worse, spills on you. I stirred the pot every 15 minutes so that all cloth surfaces were exposed to the scouring, and adjusted the temperature as necessary to keep an even boil.

The scouring raised the pH of the cloth from around 5 to 7, though this was measured with testing strips and is likely not super accurate. Soda ash is around 10 or 11 pH. The scouring removed oils, waxes, and pectic substances. The cotton fibers swelled and softened during the process.

Muslin samples pasted onto Mohawk Superfine. Left: Scoured. Middle: Washed. Right: Untreated. Note the superior adhesion of the scoured sample, skinning the paper during a pull test.

The difference in adhesion between the scoured, washed, and untreated samples is remarkable. All were pasted with Aytex P wheat starch paste onto a piece of Mohawk Superfine, with the same weight during drying.  I testing the adhesive strength by pulling the fabric away from the paper at 180 degrees. The scoured sample delaminated the paper, while the washed sample (hot water, a tiny bit of Seventh Generation Free and Clear detergent, industrial washing machine) and untreated sample released without affecting the surface of the paper. I tried this two more times, and the results were the same. In a separate test using EVA all the samples delaminated the paper.  I’d like to get a push-pull gauge to quantify the adhesion a bit more rigorously. Of course, there may be circumstances where a weaker adhesion is desirable.

But for most book conservation applications — spine linings, board slotting flanges, hinges, sewn stuck-on endbands, covering material — strong adhesion is desirable.

 

Heat Treated Tonkin Bamboo Hera Blanks for Sale

Tonkin Bamboo. Note the large areas of black power fibers. Compare this to the endgrain of a chopstick.

Hera are small Japanese tools useful for a variety of scraping, lifting, and delaminating tasks. They are common in paper conservation. Tonkin is a dense, flexible and strong type of bamboo that handmade fishing rods are made from. More about Tonkin.  Heat treating increases the elasticity of the bamboo.

Even so, hera with very thin and flexible tips can wear and can crack, so they need to be maintained by sanding, carving, reducing the width, or even shortening.  Once you have the skills to make a hera, they are easy to maintain. If you want to keep things simple, shape it with your Olfa knife, sand it with 220 grit, then finish it with 600 grit.  More tips on shaping bamboo.

These blanks are roughly 6 inches long, and 1/4 – 3/8 inch wide.  If you want to make two narrow hera, you could split a wider blank.  Just ask me for the widest one I have. Making your own tools to the exact size and shape you need is rewarding and satisfying.

Purchase heat treated Tonkin hera blanks here, only $10.00/ each!

An Ornate 17th Century Bookbinding Press

This is the most ornate finishing (?) press I’ve ever seen, as well as being one of the earliest dated ones. It is inaccurately described by the V&A as a book stretcher in the catalog, because in the early images (above and below) the tightening nuts were on the wrong side of the cheek. Usually tightening nuts like these are found on German or Netherlandish presses.

It would be nice to have a book stretcher on occasion, though.  Need to turn an octavo into a quarto?  No problem!  But was this really a book press, or a press intended for some other purpose? The 29 inch long cheeks are very, very thin in profile, and I imagine would deflect quite a bit even with just hand tightening.

A later image shows the press assembled correctly, but it is still described as a book stretcher. Almost every non-functional inch of this remarkable press is covered with relief carvings. The tightening nuts are especially elegant.  It is made from walnut, a wood traditionally used for press boards in 18th century France.

Many 17th century and earlier European woodworking tools, like planes, are encrusted with carving. Hand tools have became minimally decorated since the 20th century, all form deriving from efficient manufacture and use. The decorative deep carving must have taken a lot of extra time. Did the maker or consumer provide the agency? Was this a presentation piece, not intended to be used?  It seems to show very little wear, atypical of most presses. Or did the maker just want to make a beautiful tool? Do beautiful tools inspire binders to make beautiful books?

Keep it Clean: Preserving the Life of 3M Finishing Film

One of the most common mistakes in sharpening is to allow your stone or film to glaze over. This significantly increases sharpening time, since the knife is not abraded by the grit, but is burnished against embedded steel. Not using enough lubricant is a common reason for this, as is not regularly cleaning your substrate. Depending on the size of the grit, either a microfiber rag or a white vinyl eraser works best.

My sharpening setup, above, consists of a bright swing arm lamp mounted directly above a cork faced workbench (PSA cork shelf liner), a microfiber rag, a large squeeze bottle of water, and the Peachey Sharpening System. I find it more comfortable to sharpen at a lower height, around 34 inches, than my regular bookbinding workbench. Many hundreds of knives have been sharpened here!

The microfiber rag is perfect for cleaning larger grit 3M micro-finishing film, from 80 to around 15 microns. This rag was white when I purchased it, a testament to how well it picks up and retains small metal particles. I also use it to clean off the knife between grits in order to examine the scratch patterns.

For 5 micron and smaller grits, a white vinyl eraser works wonders.  Pictured above is the neon lime green  1 micron film, which glazes quite easily. Using the eraser on coarser grits eats it up too quickly.

Of course, over time, the abrasive will wear to the point nothing much happens, and you will need to replace it. I can usually sharpen ten knives or so on one piece of 2 x 11 inch film.

By using plenty of water as a lubricant, and cleaning the film after each use, the effective working life of finishing film will be prolonged.

The Conservation of Dante’s 1477 La Commedia. Lecture Synopsis.

Ndpreservation posted a nice synopsis of my lecture about the conservation of Dante’s 1477 La Commedia.  It was an interesting and time consuming treatment, involving both resewing and rebinding in an alum tawed goat conservation binding.

This treatment provided impetus for further investigation into the history of conservation binding, both the term and the practice.  I will present an updated version of this lecture on November 7, 2018, 10:00 am,  Jones Room, Woodruff Library, Emory University, Atlanta, GA.

I’ll also be teaching “The Conservation of Leather Bindings”  that week at Emory. The application deadline is this Friday, September 14, 2018.

Upcoming Conference: Technical cultures of repair, from prehistory to the present day

Damn, this is a great looking conference in Paris next summer. The deadline is September 30 2018 for abstracts. It is always a bit of a long-shot for conservators to participate in “real” academic conferences, but this one is so relevant. I hope we are represented: after all, this is what we study, think about and do on a daily basis. There is a very useful Bibliographie indicative attached to this call (below), suggesting a strong anthropological basis. Note the Vance Packard book — is he relevant in academia now? — and the continuing importance of Appadurai’s “Social Life of Things”. A publication is planned after the conference.
Thank you Sarah Lowengard for bringing this to my attention.

Technical cultures of repair, from prehistory to the present day

International meeting
Paris, June 17-18, 2019

Repairs are a special moment in the “biography of an object” (Appadurai, Kopytoff). Although it was taken off the market circuit when it was bought, the object returns to the field of exchanges after being repaired, following an accident, wear and tear, or due to shortages or political commitments to sustainable consumption. This circulation generates knowledge and know-how, it involves professions and sociability (often gendered), it enhances the organization of a production system, largely supported by subcontracting networks and decentralized workshops, including in the contemporary period. Even in electronic processes, supposedly preventing any appropriation, are nestled complex embodied know-how, cultural cements of established professional circles (Callén). Recent creations of repair sites for electronic equipment attest the strength of this model but also the emergence of a new consumerist logic. Renewed studies since a generation on the restoration of technical objects in museums converge with these subjects dealing with “the life of the objects” (Bonnot) by asking the question of the limit between the necessity to repair and the preservation of traces of use, this limit materializing the distinction between a functional object (being repaired) and piece of art (being restored).

Research in archeology is full of examples of repairs at all times. Since the Paleolithic, societies have repaired flint, either to sharpen sharp tools or to produce other tools. It is then necessary to distinguish what is of the order of repair to retain the desired use of the object, and what is associated with true recycling using a partially formatted raw material. The analysis of repaired objects allows us to understand the reasons for the repairs and to approach the values ​​assigned by each community to the objects in question. In some cases, this may involve repairs to an object that has caused a considerable workload; in others, the symbolic value of these objects has created a need to preserve them, as it is illustrated by the case of ceramic material.

The gap is to be emphasized with the historical works. While the history of consumerism, which has been booming for a generation, has been heavily influenced by second-hand sales, the prolongation of life of objects in scarcity societies and recycling circuits, the history of repairs was not often addressed.  Similarly, the interest in re-employment in approaches crossing anthropology, ethnology, sociology, archeology and the history of technology has quite neglected the study of gestures, places, knowledge and repair circuits. Business archives suggest, however, over the long term, the extent of repairs in craft and manufacturing enterprises, sometimes along intercontinental circuits. Recent approaches show the importance of these everyday and repetitive techniques in the reconfiguration of trade identities around operative skills and in the emergence of transverse production sectors, for example for the supply of spare parts and fasteners. It belongs to the history of the rationalization of work, as already shown by the studies on artillery (Alder) or on shipbuilding (“From repairs came industry,” said Hélène Vérin). Thus, repair techniques are part of the concept of “technology’s middle ground” by which Kevin Borg defines “an ambiguous space between production and consumption”.

While the transformation of production methods in the 19th century through the interchangeability of parts led to a “discipline” of repair, in the 20th century the planned obsolescence introduced a new relationship to the object that excluded any possibility of repair – hence transforming the goals assigned to engineers. This disappearance of the repair prompted the reactions of sociologists in the 1960s (Packard) and more recently, of consumer groups (and their lawyers, like against Apple in 2003), of journalists (Slade), and even industrialists concerned with sustainable economy (Warner et alii). In the 20th century, whereas the era of mass consumption diffused the culture of the ready to use and throw away in the West, the communist ideology on the contrary emphasized the technical cultures centered on the extended uses of the objects in the name of the inventiveness, the rationalization and the value of human work. In the communist countries, secondary schools trained girls to make clothes and repair clothes and boys to make objects with wood and other materials (Golubev, Smolyak). Magazines and clubs promoted repairing know-how among amateurs, while repair centers were created and included specialized workshops in household technologies, clothing, shoes, etc. Planned industry malfunctions, with stock outs and systematic rejects, were then compensated by amateur and professional repair circuits and by the traffic of spare parts and pieces (Siegelbaum).

The subject opens on the place of technical action to restore and sustain the functionality of the objects – that is, the human part of technology. Western industrialization itself has fostered critical reflections on the urge to progress and the dehumanization that went hand in hand with it. In the 19th century, while mechanization and the race for power and speed led to the sanctification of technology and to the marginalization of the human factor, the place of repair was indicative of the willingness to enhance the appropriation of the machine by man (Jarrige, Barron). The milieu that was concerned with the quality of the objects, their reliability, their safety (like in the Conservatoire des arts et métiers) and hence, with repairs and maintenance, reintroduced descriptions and analysis of the human action in technical publications, and collected all sorts of techniques – everyday life techniques and micro-inventions-, in connection with the rising profession of mechanic (Dufaux).

This technical culture of repair, which has matched the intensification of production (artisanal and industrial) and which has received its theorization (Simondon) raises the question of the temporalities. Are mending techniques to be assigned to a traditional material culture or do they participate in new know-how? Ordinary repairs in the countries of the South and in Asia are emblematic of a plurality of temporalities. The work on repairs in Africa shows the way here (Speranza). Scrubbing, sanding, varnishing are all acts that anticipate degradation and are part of a maintenance economy, suggesting the need to study the temporality – and  the words (Roulon-Doko) – of this complex activity, occasional and / or regular, combining the short-term and the long-term life of objects (Dupré). These daily and ordinary repair cultures are widely found in developing countries and continue today. But the current situation of countries such as Ghana which is subject to the dumping of electronic products from developed countries, repaired for resale or recuperated (waste fields), raises the question of the articulation of these new intensive practices – an expression of obvious economic domination – with traditional ones inscribed in very different logics. Moreover, whereas it is quite usual to consider repairs as part of the so-called informal economy (Cheneau-Loquay), the last decades have been blurring the border between the circuits of objects in rich and poor countries because of the emergence of the culture of reparation as an ecological approach and as a citizen commitment to slow consumption. The economy of recycling and re-use reflects an institutionalized concern for the environment – that is questioned (Monsaingeon) – in addition to individual repair practices (Anstett, Ortar).

Finally, repair is a reflexive operation, which purpose is not only the restoration of a disturbed function or a damaged envelope, but also the investigation of the causes of dysfunctions, which is part of the improvement and the perfecting of devices, and belongs to the innovative practices (Jackson). Beyond this, repair is resurfacing today in an unexpected way, as a claim of technical intelligibility that undermines the topos of the gap between manual and intellectual activities: this reconfiguration could invite us to rethink our conditions of access to reflexivity as being originally and always already technological (Crawford).

This symposium proposes to examine the evolution of repair practices and cultures in the long term, in a global and comparative perspective. It intends to examine the sites of repair (factories, docks, workshops, clubs, garages, home, etc.), the figures of the repairer (the amateur and the professional) and the ways in which the functionality of objects is envisaged during repairs (repair as restoration or repair as transformation). An approach based on geographical areas should allow the identification of circulations of models and repair techniques from one region to another, and understand how such circulations impact the economy and techniques around the world. The object is at the core of our approach – its materiality, its circulations, its biography allowing to grasp the cultural contexts in which to consider repairs.

Abstracts (max. 1000 characters) along with a CV should be sent to liliane.perez@wanadoo.fr and to larisazakharova@gmail.com by September 30st, 2018 at the latest. Presentations and discussion will be conducted in French or English. The symposium will lead to a publication.
