Adding Colourants in 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.
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.
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
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?
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.
