I've read that some gunmakers would urinate on the bone and wood charcoal pack in their crucibles before it went into the furnace. Supposedly this enhanced the colors. Have you heard of this or tried it?

A word of warning though... When I worked in a blast furnace years ago, sometimes someone would piss in the coke dust that lined the iron runner. When the molten iron hit it, the resulting odor from the superheated human urine was worse than a herd of skunks.

Voting for anti-gun Democrats is dumber than giving treats to a dog that shits on a Persian Rug
