What I have done:

I cut and treated a couple slabs of 182 white stoneware and I made a CAD drawing to laser cut and went to the shop and attempted to cut it.

What Happened:

Stoneware is heat resistant and the laser cutter struggled to get even half way through. Interestingly the silica content in the clay turned to glass where the laser cutter cut.

What I am going to try next:

I am going to try to roll out significantly thinner slabs of porcelain. I am changing the material because porcelain has a number of unique qualities stoneware does not. Porcelain can sustain being rolled out into much thinner slabs and it can also appear almost translucent when fired. if I can cut out the porcelain I will do that but if I cannot I will etch designs into it so that the design appears almost translucent.

Materials:

Since I already have a full 25 pounds of porcelain I don’t think I will need anywhere close to that amount, and other than the laser cutter that is all I am going to need.
