This is a very special mould to make a medium size but fairly deep bowl. The result can be a simple piece or artwork as well as a utilitarian object in the dining area. Combine with 958.343 Small China Soup Bowl & 958.347 Breakfast Tray.
Instead of cutting the glass round try a square piece instead. Fuse identical pieces from two contrasting colours. The steep angle of this mould will reveal the bottom colour around the edges.
