That’s why today I decided to gather 5 of our best ceramic glaze testing resources from over the years in one place. The posts below will help dispel any glaze testing phobias you might have or get the most out of any testing you may already do. See, glaze chemistry isn’t so scary after all! - Jennifer Harnetty, editor.

Improve Your Surfaces by Testing Your Pottery Glazes
Remember, in high school chemistry class when you found yourself thinking, “when will I EVER use this stuff in my life?” (unless, of course, you always dreamed of becoming a chemist). Well, if you became a potter, chances are you have found yourself getting reacquainted with some of the terminology from high school chemistry. If… Read More »
If you’re like me, the mention of the word chemistry can send you into a panic – admittedly not my favorite subject. But I love ceramics, so I realized a while back that I had to face my fears and try to get a grasp on glaze chemistry. Yes, a general knowledge of ceramics chemistry… Read More »
A triaxial blend is an excellent tool for learning about glazes and materials but if you’re new to glaze testing, just the words “triaxial blend” might give you pause. Never fear! John Britt is here to demystify the triaxial blend in today’s video post. In this clip, excerpted from Understanding Glazes: How to Test, Tweak,… Read More »
Let’s face it. We’ve all had glaze disasters in the kiln. From the mild disappointment of a glaze not turning out exactly the color you were hoping for to a glaze completely running off a piece and ruining a kiln shelf. That’s why it is so important to test our glazes.Line blends are a pretty… Read More »
The best way to learn about ceramic glazes and glaze materials is to test them. By studying what happens when varying amounts of various ingredients are combined in a glaze and then fired to various temperatures, you start to understand how materials affect each other, and therefore how to troubleshoot when your results are not… Read More »
