When a taxidermy mount is made, the skin of the mammal (and in some cases reptiles and birds) is usually tanned. Tanning is the process of turning a raw skin into leather using chemistry. By turning the skin into leather, we are changing a fragile perusable material into something durable that can be sculpted into taxidermy and be more resistant to insect attack. Tanning the skin involves removing proteins in the skin and loosening the collagen fibres and then attaching tannins to these structures. Leather can be made with either the hair on or off the skin. When we are making taxidermy, we want the fur to stay attached to the skin and so the process is different to when the fur is to be removed. With hair on tanning, we want the pH to stay low to prevent the fur from falling out. The skin starts by going into a pickle solution of around pH 2 and after it has been through the tanning process it ends up at about pH 4.5 -5.
