Jiggering Molds, Large Cross-sections
Backside of a 92% alumina, 45% open porosity mold. The front surface is
used for jiggering plates. Note overall diameter is about 10 inches.
See detail below illustrating 1-inch wall transitioning to 2-inch and 3-inch
walls.
The 50-50% alumino-silicate body [below] demonstrates closed porosity.
Total porosity is about 85%. The block is floating in water.
