Here I cast Smooth-Cast 300 urethane resin into several types of molds. I find that each mold has it’s own issues. Because resin can only flow where gravity can take it, your mold might have air bubble issues. After a while I learn how each mold needs to be dealt with in order to get a good casting. I find myself jiggling, shaking, or swirling some of my molds in order to get resin into the hard to reach areas of the mold. Sometimes I even cut a vent to get resin to flow properly. For complete illustrated information check out my book, How To Make Resin Toys by J.E.Moores.
