How One Workshop in Jura Turns Horn into Spectacle Frames

In the village of Morez in the French Jura, Maison Bonnet has produced spectacle frames from natural buffalo horn since 1950. Each frame requires six to eight hours of handwork to shape, assemble, and polish, beginning with raw horn from water buffalo and ending with glasses sitting on the face with warmth and individuality acetate cannot replicate.

Buffalo horn is a keratin composite, the same protein family as human fingernails. It is warm to touch, hypoallergenic, and lightweight. Unlike plastic arriving in uniform sheets, horn is a natural material with unique colour variations, striations, and translucency in every piece, guaranteeing no two Bonnet frames are identical.

The raw horn arrives as flattened plates created by sawing horn lengthwise, heating in boiling water, and pressing flat. Plates range from pale blonde through amber to deep black with infinite variations. The frame maker selects plates whose colour and pattern complement each other for front and temple pieces.

Shaping is done entirely by hand using files, rasps, and sandpaper guided by templates. Horn is heated gently to make it pliable, bent to required curvature, and held in jigs until cool. Hinges are fitted with stainless steel rivets into precisely drilled channels requiring extreme care to avoid splitting.

The polishing process gives horn frames their distinctive lustre. Progressive buffing with fine abrasives reveals natural translucency and colour depth. Light passing through a horn edge shows amber striations reminiscent of tortoiseshell, earning horn frames the description of the only eyewear material improving with age.

For genuinely distinctive glasses, consider horn frames from a specialist maker. Expect to invest between eight hundred and two thousand euros and visit the workshop for personal fitting. The result is eyewear expressing individuality through natural material beauty rather than logo display. Commission at https://www.maisonbonnet.com
