The liquid plastic is curing in the rubber molds. The finished records will be a translucent white. It was difficult to judge the exact amount of plastic needed to fill the mold without spillover. When the plastic hardens and is able to be removed from the mold I'll have to cut off and sand any excess around the edges. (The grooves, of course, are on the bottom side.)
To create the mold I poured the liquid rubber compound over a dub plate I had manufactured from the original demos (see June 25, 2007).
