Material Substitutions with Glazy.org – Video Tutorial
Glazy.org is a free ceramic recipe sharing website where users can upload glaze recipes and photos to share with the ceramics community.
In this tutorial, I show you how to use Glazy to make material substitutions using the UMF (Unity Molecular Formula).
What happens if you run out of a material, or you don’t have access to a material you find in a recipe? You can easily substitute one material for another by matching the chemistry. In this video, I replace Whiting with Wollastonite.
Learn glaze chemistry
Glazy.org isn’t just a place to store recipes and images. It also has the benefit of being a glaze calculation software that converts recipes to their Unity Molecular Formula (UMF) so you can see the underlying chemistry of each formula.
If you’re a glaze nerd like me, this is very important information to have in front of you while viewing a glaze recipe. If you want to learn glaze chemistry, it’s a great way to get used to looking at the UMF, even if you don’t know what it means yet.
Glazy.org was created and is maintained by Derek Au. If you love Glazy like I do, consider supporting Derek so he can keep the site up to date and running smoothly for all of us https://www.patreon.com/derekau

Learn to Mix Glazes from Scratch
If you’ve never mixed a glaze from scratch before and want to learn, I teach an online workshop called Glaze Mixing Essentials where I show you all the steps to mix a glaze and then test a base glaze with multiple colourants. Click the link for all the details.
