Plaster mold from clay model and plaster preparation stages

Hello. In this video, I show how to prepare a plaster mold from a clay model. Our clay model is leather hard and its wall thickness is about 1 cm. Also, the model is solid. The reason why it is solid is to eliminate air resistance inside. Because in the opposite case, an object with air inside will be forced to rise constantly while in liquid. For this reason, it is solid. In the continuation, I will show the preparation stages for plaster casting and other tricks. If you have any questions, I am waiting for your comments.
