Understanding the relationship between a pour and its mold means understanding the relationship between the negative and positive spaces of your design. After playing around with a few simple plaster pours, some alone and others in plastic bags, I realized I wanted to have the mold on display along with the pour, all in one piece with both being visible. Eventually, I came to a design where plaster would be poured into a plastic bag suspended by piano wire. The result showed a really interesting and beautiful relationship between the pour and its constraints.
