Glazy.org is a website where users can upload their ceramic recipes with images, to share with the ceramics community. Anyone can create an account for free. You can search for recipes based on colour, texture, temperature and more. Click for more info.
Are you ready to start mixing your own glazes? Perhaps you’ve reached the point in your ceramics journey that you want to start understanding the materials you’re working with and what is actually happening when you put your pottery into the kiln.
Most of our glaze materials come to us in their very basic, unprocessed form. They are dug out of the ground, impurities may or may not be removed, they are ground into a fine powder, bagged and shipped to our suppliers. Working with these minerals in their raw state poses some health risks.
When a recipe adds up to 100%, we can easily compare it to other recipes. This is particularly useful when we have additions like colourants and opacifiers. The base recipe remains constant while the additions are always relative to 100%. It also allows us to look at 2 recipes side by side and compare the amounts of individual materials. But what do we do if our recipe doesn’t add up to 100%?
"Understanding Cone 6"
NCECA presentation - 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?
