If you’ve been following my process of making the Ploughshare Tortoise, I have finally completed the mold and ready for casting. Plaster process is difficult as this was an unconventional shape, and it is important to hide the seams to prevent a lengthy clean up. .
Getting through the plaster part is one phase, the second phase is knowing if it will cast (properly). Bubbles, chips, undercuts, are all concerns that may prove the hard work and long hours of designing, modelling, and mold making entirely useless. .
First cast in the slipcasting world is usually unsuccessful. And of course, here it is...
Casting slip is not like solid clay, where at bone dry, you can break it and reuse it, because of the deflocculant in the slip that keeps it liquid. So if the cast does not come out right, it goes straight to the trash bin... so why not have some fun?
