If you’ve never used Glazy.org before, this is a helpful tutorial to get started. In this tutorial, I go over the basics of using the site.
In this tutorial, I go over how to add colourants to a recipe and keep the colourants separate from the base recipe so your base adds up to 100% and your colourants are shown as additions.
In this tutorial, I show you how to use Glazy to make material substitutions using the UMF (Unity Molecular Formula).
If you have too much clay in a glaze recipe, you might have issues with your glaze crawling during the firing. Crawling is where the glaze pulls away from the clay body due to a combination of shrinkage, poor adhesion and high surface tension.
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.
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%?
