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 Kjelli ----- Original Message ----- From: Sam Cardinal <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]> Sent: Tuesday, March 20, 2001 4:12 PM Subject: Re: [RCSE] Thermal expansion of lead!! > 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.
