Making a tea glass holder for an existing glass.
My glass was tiny, so I developed a concept which made it possible to hold it by sticking only one finger through the handle.

Building the mold.
I had the idea to place the teapot diagonally in the mold to achieve a diagonal layering of the porcellain, which supports the design. Then used the laser cutter to cut cardboard into pieces of the sliced mold model and assembled the pieces after cutting.
The next step was pouring the porcellain.

Casting process.
Spinning the mold with the porcellain continously for half an hour before emptying the excess. In the drying process the remaining outer porcellain layers solidified, as the cardboard absorbed the water. The last step was to strip the formwork after it dried for some days.
The first result after stripping the formwork.
