    Default Its for tanning leather

    Seen this in Marrakesh, Morocco as well. Ponds filled with urine, bird droppings and other nasties used to tan leather. You wait till Google Earth has a smell function...

    ...Tanners would take an animal skin and soak it in water. Then they would pound and scour the skin to remove flesh and fat. Next, either they soaked the skin in urine to loosen hair fibers or they let the skin putrefy for several months, after which they dipped the skin in a salt solution. After the hair fibers were loosened, the tanners would scrape them off with a knife.

    Once the hair was removed, tanners would bate the material by pounding dung into the skin or soaking the skin in a solution of animal brains. They would also take cedar oil, alum, or tannin and stretch the skin as it lost moisture and absorbed the tanning agent...
