Some RE-TANS from Spain..Had absolutely ZERO STRETCH.. 2- ibex, and a Chamois cape
Iron somewhere in their process, weather it be tannage or salt, reacted with the pickle, and formed Iron tanate..(the black skins)
Charles Charles did his own research and figured out by using oxalic acid as a chelating agent, he could reverse the bond of the Iron tanate, and remove it from the skins all together!
All Iron removed, skins tanned again properly, with stretch and very little memory.
Iron tanate left in skins can eventually lead to rapid degradation of collagen, just fyi...
Thanks Charles for going the extra mile for our Customers!
