..results quickly. On disc two, John geeks out on materials, diving into the three basic components of a glaze—fluxes, glass formers, and refractories—and how various ceramic materials fit into those categories and work together to produce myriad outcomes. With this video, you’ll be able to deepen your understanding of glaze chemistry and improve your glazes at your own pace. Original List Price: $69.97
This video was absolutely perfect for my level of understanding. He really explains the concept simply without dumbing it down. I just opened a studio and now I feel I can develop my own glazes confidently. — Dan, New Jersey
Even though I am French, his explanations were very clear. His method is easy, very practical, it makes you want to make lots of tests with glazes! — Andrée B., France
Glazed and confused?
Help is on the way, and it’s not as bad as you think. John’s approach to teaching glazes is simple and straightforward as he guides you step-by-step through the process. With easy-to-follow instructions, you’ll begin with an overview of the tools and supplies you’ll need to get started. He recommends grabbing some recipes from friends, books or the Internet—this isn’t about creating a glaze from scratch but more about how to understand what a glaze is and what happens when you change things in it.
Test, test, test
The best way to understand glazes is to test them—lots of them. But, here’s the shocker—John’s technique for testing is one of the simplest ones you’ll ever follow, and before you know it, you’ll have dozens of fired glaze results that you can look at, study, and make even more experiments with until you’ve come up with your own truly unique glazes. How do different feldspars affect color? What happens when you increase or decrease silica? These are all some of the things you’ll discover when you test.
Nuts and bolts
Once you understand how the materials in your glaze work when fired in different proportions, John gets into the function of each type of glaze material. With this basic knowledge of types of materials, you’ll be able to make educated decisions about the next new glaze you want to try, or you’ll be able to look at any glaze and figure out how that color or surface effect was done.
Along with the DVD, you’ll get valuable bonus materials you can print out or view on your computer. These PDFs include an assignment to get started, an oxide reference giving you the basics of all the ingredients you’ll use, sample recipes with photos of glazes from different firing temperatures, and diagrams for how to make triaxial blends.
Time to start
If you’ve always been curious about what it takes to make your own glazes, John Britt provides an easy way to get started. His knowledge of testing, opacifiers, colorants, glass formers, metals, and fluxes will help you in your own pursuit of developing truly unique glazes that only you will use. Once you know the technique, the colors and effects are literally infinite!
