Here's my first creation from this "Reproduction in Plastics" class that I'm taking. Ok... it's a little rough but I still think it's cool. In the first class, I started off by making a small dog out of clay. Then I made a mold of it out of rubber. The mold was still a little soft so we let it set until this week's class. Last night, I pried out the clay dog and filled the mold with polyuthrane. The polyuthrane sets pretty fast. You start mixing the two chemicals and it start to heating up and harden.
