Hello everyone! Another question from me: is it possible to cast a flat plate (without a foot) with a one-piece plaster mold? I am usually throwing a prototype with a simple white clay on a wheel, then wait until its dry enough and cast a mold, but when i tried making a plaster mold for a flat plate, plaster seemed to heavy for the clay to hold, clay got softer and caved in. As the result: the mold is with a little knob in the middle. Any advices? Thank you! Nata
