I grossly overestimated the amount that the mug would shrink in the mold. Scraping the trouble spots on the mold away with an exacto knife got rid of most of the problem, the rest is generally repaired in the cleanup phase. Yes, the better the mold the easier and quicker the cleanup. I was still sculpting Fred at this point and gave him the necessary adjustments to make for an easier pull. A good lesson learned. Meanwhile, Pina Diablo was made with a FIVE part mold! So no undercutting problems there. Coconut and Alien use four part molds. But that's a whole new story... The good news here is that HMC is using a silicon master and can just toss the mold if it sucks and try again, no harm done to the original art. -Joe
