I finally got to pour the mold that I made about 4 weeks ago in metals class. I had to fill up the crucible full of 6061 T6 aluminum slowly for about an hour, then wait about another half hour until the foundry heated the molten aluminum to about 1600f. Once that happened, I pulled the whole mess out of the foundry, set it in the pouring device, then me and my partner picked it up and poured the metal into the molds. As soon as the aluminum hit the styrofoam, all hell breaks loose. A huge flame shot up, which was highly unnerving, and stayed the length of the pour, filling the air with soot, smoke and awful gasses. This happens about 3 feet from your face, and you have to be very precise as you pour. This was called full-mold casting, where a styrofoam mold is placed in a bucket, then sand is packed around it and metal is poured onto the styrofoam. Whatever is styrofoam becomes aluminum. It is amazing what you can learn in college!
