I used to work at a plaace where we were melting iron. And we had a oven that was
submerged down in the floor. This made it easy to put more metal in the oven. The
whole unit could be rised and tilted for getting the 1000Degr. celsius iron out of the
oven.
When one stood beside it, one could throw a cup of coffe down and nothing happened,
(except for alot of steam comming up). The cofee vaporized on the surface. The problem
was when using iron that was rusty or wet. When this was put into the oven, the water
got below the melted iron surface, and the vaporize. This useually ended 2 ways.
Either it came a good poff sound and sparckles were raining for 10 seconds (really
cool). Or, if it was alot of water ore the water came deep before vaporizing, one
would hear a 4Xshotgun noise, and really BIG sparcks would come down for around
30seconds.
Good laugh for us that stood behind the bullet-proof window though. Never got used to
standing next to the oven when that happened. :))
Cheers

I'm afraid I must differ with you, having had a 10 lb. pot of lead
eject its contents when two or three drops of coffee landed in it. ( I
know, don't mix eating with casting, this was when I was much younger
and careless) The result was 10 lbs of lead airborne and some pretty
serious burns to the backs of my hands. NO liquids around molten metals!

Yes, but lead is some 13 times denser than water, and any water poured onto
lead will vaporize _at the surface_. Still not as good idea, but not
catastrophic.

For those out there who are unaware of it. Water will expand to 1700
times
its volume when it flashes to vapor upon hitting molten lead. It only
takes
a drop of water to empty a pot of lead. Pouring lead into a larger volume
of
water probably wouldn't do much, but a small volume of water into a larger
volume of 800deg lead will cause it to flash instantly.
