Baiting
The pepsin solution with the test strips was heated to 37 C and stirred with a magnetic stirrer.
Alum Tanning
The piece of hide in the alum tanning solution was removed from the solution, rinsed, and left to dry. It is unclear whether the alum tanning process worked. The hide appears to be more opaque and slightly more dimensionally stable, however it does not appear to have leather-like qualities.
Vegetable Tanning
The piece of hide that was in the 100% oak bark tannin solution was removed from the solution, rinsed and left to dry. The pieces of hide in other concentrations were left in solution to continue tanning.
