Advancing Glazes

Master your glaze chemistry to make your artist skill meet your artistic vision.

Course Overview

The ceramic artist strives to create glaze surfaces that, as a component of concept and content, enhance form through texture and color. The beauty of ceramic glazes comes from subtle nuances of chemistry. The intermingling of silicate bonds, crystallization, and kiln atmospheres dictate the qualities of the glaze. A fundamental understanding of the principles and properties involved in glaze science is essential if the ceramic artist can exert any control in the successful outcome of the work.

Advancing Glazes will take an intensive approach to the study and analysis of glazes. Students will research the nature of glaze effects, surfaces, and colors. The focus of the course is to provide students with technical and empirical knowledge about the composition, application and fired effects of ceramic glazes and ultimately, to aid them in making better-informed decisions as they strive to realize their vision.

***We require students take the full class of Understanding Glazes Online to establish the foundational information used extensively in Advancing Glazes class. The concepts in Understanding Glazes Online are paramount and are built upon in Advancing Glazes and are key in excelling in our Advancing Glazes class.***

Frequently Asked Questions

Answers to Your Most Pressing Questions

Science? Are you going to make me learn chemistry?

Yes! Glazes are chemical reactions, and to understand them, we have to understand chemistry.

Have no fear, part of how we teach is to craft information to make it relevant and understandable for you.

But I’m an artist. Science doesn’t apply to us. We use materials differently.

Science always applies. Yes, artists have a special approach to how we think about and use materials. We have to be considerate of what it going on in our materials. Ceramics is a scientific process, even if the result is art.

The ceramics community is wonderful, but is also filled with rumors and speculation about how things work. That information is often wrong or misleading, that can lead to work not surviving the making process. We use the best information and research to teach you how your materials REALLY work. All of our teachings are backed up by research and data, no rumors or speculation.

I live in Country X, can I participate?

We’ve taught people on every continent except Antarctica (Still no kilns down there, last we heard). The great thing about glaze chemistry is that it is universal. You may have different materials, than we do, but it makes no difference to how glazes work.

I work at temperature X, is this class relevant to me?

Yes, we talk about glazes as a whole. All firing temperatures are interrelated. We’ll teach you all of the hows and whys of all glazes.
