Endangered Expertise: The Story of Leather Conservation

Leather: the versatile material synonymous with the highest expressions of luxury and craftsmanship, yet equally bound to the most fundamental, utilitarian needs. Despite its value, much of the knowledge behind its making and care is at risk of extinction. At the Leather Conservation Centre, a small team works to preserve not only objects but an endangered body of expertise. Rosie Bolton, the Centre’s head, speaks to Lucrezia Lucas about leather’s long history, its fragile present, and the urgent task of keeping its material intelligence alive.

It lingers in the imagination both as scent and substance: the musky notes of leather in a perfume, the Americana cowboy boot, the 80s punk jackets peddled at street markets, historic gilt-leather wall hangings in grand Spanish, Dutch and English interiors.

Long before branding and industry, there was simply hide, one of the earliest materials to accompany man, used for shelter, clothing, and survival as early as 400,000 years ago. Over millennia, its transformation has approached something like alchemy: a material born of flesh, reconstituted through a precise choreography of tannins, oils, minerals, and time. A complex chemistry with a magic-like mystery; trade secrets passed down over generations and chemical recipes seldom archived.

Vegetable tannins, mineral treatments, synthetic agents; dyes, fats, and surface coatings—each stage altering not only its appearance, but its behaviour and longevity. In its complexity, no two pieces of leather are ever the same. And yet, despite this long and intricate lineage, the knowledge required to understand, preserve, and care for leather has become scarce.

The Leather Conservation Centre, established in 1978, is a rare and vital counterpoint to that loss. Its origins trace back to John Waterer (1892–1977), a designer and scholar who recognised, earlier than most, that leather’s history was dangerously under-documented. Through decades of research and writing driven by his passion for the material, Waterer laid much of the intellectual groundwork for the field. In 1946 he published Leather in Life, Art and Industry, one of his many written contributions, and in the same year he founded the Museum of Leathercraft in Northampton with Dr. C. H. Spiers.

The Leather Conservation Centre emerged as Waterer's most ambitious legacy: his “brainchild”, a space dedicated not only to preservation, but to understanding. He tragically died just a year prior to its opening.

Even today, it remains a remarkably niche institution within an even niche-er discipline. As Rosie Bolton, Head of Centre, makes clear, this marginality belies an immense and ongoing urgency. Leather, she explains, is profoundly under-researched on a global scale. Historically, its production relied on tacit knowledge: trade secrets passed from hand to hand, generation to generation, rarely documented. When industrialisation accelerated, particularly in the interwar period, many of these practices simply vanished. What replaced them was scale, speed, and chemical innovation; what was lost was continuity.

This rupture is still felt in the conservation studio today. Objects, from private and historical collections, arrive bearing the marks of processes no longer practiced, materials no longer available, recipes no longer known. A pair of inherited gloves, for instance, might appear unremarkable until placed beside their modern equivalents, where chrome tanning and industrial finishing have produced an entirely different material, with different ageing properties and vulnerabilities.

Within the Centre’s workshop—modest in size, a team of five, with just three hands-on conservators—this complexity plays out across an extraordinary range of objects. A hat box of imposing scale. A sedan chair. Parchment documents. Chairs both grand and domestic. Panels of gilt leather from Oxburgh Hall, their surfaces shimmering with a peculiar depth: silver leaf overlaid with yellow varnish to imitate gold, embossed into low-relief patterns.

And cars. The Centre is among the very few institutions to approach automotive interiors not as replaceable components, but as historical artefacts. Where standard restoration might strip and refit, conservation insists on retention—on preserving original material wherever possible. It is a practice governed by strictly laid out ethics; a philosophy that guides each project.

Bolton stresses that conservation, at its core, is not restoration. It is a discipline poised between craft and chemistry, where eahc intervention must be justified. To repair an object is not simply to improve its appearance, but to understand it: how it was made, how it has aged, how it will continue to alter over time. Any added material must be chemically compatible, stable, and reversible where possible. In leather—organic membrane combined with complex processing—this is particularly challenging.

It is perhaps surprising, then, that leather itself is not always the primary material used in its repair. Instead, conservators frequently turn to Japanese papers—particularly kozo, a mulberry fibre of exceptional length and strength. Soft, almost cloud-like in its raw state, it can be dyed, toned, and finished until it closely resembles leather, while remaining more stable and predictable in its ageing. 

Beyond the studio, the Centre’s work extends into education. Misconceptions around leather are widespread, particularly in relation to treatment and sustainability. Leather is deeply entangled with long histories of animal husbandry and human consumption. Its environmental impact thus depends on methods of production, sourcing, and use.

To address this, the Centre has developed practical training programmes that reconnect participants with historic processes. In partnership with ethically managed sites such as Bradgate Park, materials are sourced with care and transparency: deer skins from controlled culls, alongside bone, antler, sinew, and even internal membranes. These are not curiosities, but reminders of a time when no part of the animal was wasted, when material knowledge was inseparable from daily life. Gut, for instance, once processed into translucent sheaths or objects of surprising delicacy; camel bladder, shaped into vessels; rhinoceros hide, formed into shields.

Such examples expand the definition of leather, revealing a material shaped by culture, geography, and necessity. And perhaps this is where the Centre’s work feels most radical. Not in the scale of its operations, but in its respect for the material and an insistence on attention to history and process. In a moment where luxury leather goods are once again predominant, the need for such attention becomes more acute. 

Leather, after all, has always been both ordinary and extraordinary. A material of survival that became a marker of status; a craft that slipped into industry; a history that, for a time, went unwritten.
