Vegetable Tanning: The Six-Week Process
Pits, bark liquor and time. How the oldest tannage still produces the best belts and tooling leather.
Vegetable tanning is a slow gradient: hides move through progressively stronger tannin liquors so the centre of the hide tans as evenly as the surface.
Gradient tanning
Rushing concentration case-hardens the surface and leaves a raw core.
Tannin sources
Chestnut, quebracho, mimosa and oak each shift the final colour.
Drying and currying
Slow drying and oiling set the firm temper that belt makers need.
