To make this work I apply a grid to the surface of a solid plaster model that is made using the potters wheel for throwing, or turning (sledging) setting plaster. I then use this grid to create a layered geometric design. Much of the process is documented in my IG feed. I make my own molds, casting slip, glazes etc. My work is food safe. The interiors are glazed. The exteriors are glazed and unglazed, wet sanded surfaces that are Satin Matt. The unglazed surfaces are vitrified and water tight.
