Free Guide

Do you have these glaze challenges?

  • You don't know how much water to add to your glazes
  • You get different results every firing
  • Your glazes aren't turning out as expected
  • You can't seem to keep your glaze thickness consistent

Grab my FREE GUIDE

You'll start understanding your glaze results better when you measure specific gravity. It just takes a few simple steps to calculate the water content of your glazes and then it's easy to keep them consistent. No more guessing!

Consistent water content = consistent application thickness = consistent results.

"Understanding Cone 6" - Pittsburgh 2018

My NCECA presentation Understanding Cone 6 is all about using glaze chemistry, the Unity Molecular Formula and the Stull chart to understand how different surfaces are created at cone 6.

Which glaze formulas are likely to be matte or glossy? Which ones are likely to be crazed or be under-fired? How does flux ratio impact fired results?
