Bating and Pickling
The bating and the pickling make the fibers of the hide more receptive to tanning.
Bating
The hides are treated with enzymes, similar to those found in the digestive system, to degrade proteins. The hides become softer by this enzyme treatment. The softer the leather has to be, the longer the bating is performed.
Before industrially produced components were available, bird droppings and dog feces have been used for this procedure.
Pickling
The Pickling process makes the fibres of the hides more receptive to tanning. Pickling increases the acidity of the hide to a pH of 3, enabling chromium tannins to enter the hide. Salts are added to prevent the hide from swelling. For preservation purposes, 0.03 - 2 weight percent of fungicides and bactericides are applied.
