Adding Colourants in Glazy.org – Video Tutorial
Recipe sharing
Glazy.org is a free ceramic recipe sharing website where users can upload glaze recipes and photos to share with the ceramics community.
Adding colourants to a recipe
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.
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.

Hello Sue,
I am sad not to join your online course this time.
I have been watching as much as I can with your posts. Thank you.
I am sure this has come up before however, making glazes with a different temperature to what is shown. For example: You fire to ^6 and I fire to ^04 as well as a higher bisque. How do we calculate the materials in a glaze to fire to a lower temperature?
Hi Maggie,
I’m glad you’re enjoying my posts. I’m not sure I understand your question though, so maybe you can clarify. If you’re firing to a lower temperature, you would use recipes designed for that temperature. This post is about adding colourants to a glaze recipe, and that process is exactly the same whether you’re using a cone 6 recipe or a cone 04 recipe.
