I'm a goldsmith in real life, and aqua regia has uses in that line of work. It was posted in a professional forum but I figured it could use wider exposure. I was waiting for the "Burma Shave" tag - it's in the exact same style and meter.

LOVE the old Burma Shave road sign doggeral. :-)
You're a goldsmith ? How interesting !
