I've been looking to explore some new ideas for making bowls, something that is more fitting with the faceted mugs I make but not so nearly as time consuming.These are thrown, then turned before being pressed over a plaster mold.
I plan to use a simple glaze as the form is quite complicated in its self. I made two molds with the same shape but in two different sizes. The most difficult part of the process that I found was working out the size of the thrown form, too shallow or deep and the rim of the pot can split easily when pressed. The plaster mold started as a CAD drawing and then produced using the 3D printers at the institute of making UCL, @of_making where I work. Untrustworthy of the CNC, I Vac formed the print to allow me to take a quick 1 part cast. I then proceeded to cast in plaster an additional cylinder underneath to raise the mold up to make pressing easier whilst working on the wheel.
I’m sure many would be able to sculpt the mold from clay to then take a cast, but sculpting isn’t my strong point. I also really enjoy the process of solving problems and making tools to aid me in my making.
