How leather is graded, tanned and stitched, and how to recognise craftsmanship that lasts.
How leather is graded, tanned and stitched, and how to recognise craftsmanship that lasts.
Tanning and Production
Chrome tanning uses chromium(III). The concern is chromium(VI), limited to 3 mg/kg in EU skin-contact leather. Learn how it forms and what to ask a maker.
Tanning and Production
Chrome-tanned leather is tanned with chromium(III) salts in a drum in a day or two. See the steps, what wet blue means and how it changes a jacket.
Tanning and Production
Bark-tanned leather is vegetable tan made with oak or hemlock bark in pits over months. Compare timings, barks, history and where it is used.
Leathercraft and Construction
What skiving does at a leather jacket seam, collar and hem, how hand knives and bell-knife machines differ, and where makers disagree on thinning seams.
