Just a quick follow-up to the previous post; the new Cutting Horse sculpture has been cut out of his waste mold! You can see that the soft clay original sculpture of ChaCha did not come out unscathed, he lost his ears and the front leg sure got pulled apart.
But that's not important at this point.
What's important is that Barry got a really clean looking imprint coat, i.e. the first coat of rubber that captures all the detail of the sculpture.
Bubbles in subsequent layers are not a problem in a waste mold. If this had been a mold designed to cast a smaller resin under pressure Barry would have placed the rubber in a vacuum chamber to extract air prior to pouring a sturdy block mold. Another approach to mold making altogether actually. And, good subject for a future post. In the meantime I'm eagerly awaiting the first resin to be cast from this mold so that I can get to work finalizing a master copy of ChaCha.
