Making an Organic Aluminum Sculpture out of Styrofoam!

Here are some more photos of the finished cast aluminum sculpture: / cqw3knyo7ch
Thanks again to my classmates Viktoria and Ellison and my professor Kevin for helping with the aluminum pour!
Also a little more clarification on the step I wasn't sure about, where nitrogen was being injected into the molten aluminum. This is called degassing, the nitrogen flowing through the aluminum bonds to hydrogen atoms in the liquid. The aluminum has previously pulled the hydrogen from the atmosphere, but removing this makes the aluminum more pure and makes for better casts.
