    Aluminum sulfate is an acidic taxidermy agent that both “opens” the hide (lowering pH) and saturates the molecules / fibers. As aluminum sulfate lowers the pH, the hide is puffed up creating a more porous surface which more efficiently accepts tanning agents. Once the hide is puffed-up, the pressurized aluminum sulfate replaces organic material within each molecule with the aluminum ...
