It's funny because if you boil urine the crystals that form (KNO3) is a component in gunpowder and a few other explosives...I think the "Mythbusters" also tried to replicate "Greek fire." Have never read the original Greek fire could only be extinguished with vinegar, urine, and sand. Sand I get, that basically smothers the flame. Vinegar is acidic, but urine can be either acid or alkaline. I think text book average urine has a pH roughly that of water.
It used to be called wootz steel. There's a few companies that have recreated it to the best of their knowledge and it's full of carbides making the steel super hard but doesnt really resemble laminated steels today.Great read. Thanks. Loved reading about the Damascus steel and the alchemy that they knew about.
