seanpsilva Posted May 19, 2014 Report Share Posted May 19, 2014 Hello, I'm new here and in the ceramic world. I've been working in a project where I wanted to use Crater glaze and in my searching I found this recipe but I think there is something wrong because the total of the parts isn't 100. The recipe has parts then there are two ingredients in grams. Can anybody explain if I'm wrong in putting this question or those anybody have a crater/lava recipe? Crater Glaze – Cone 10 (I fired to cone 9 oxidation) China Clay 42 parts Silica 43 parts Potash Feldspar 159 parts Calcium Carbonate (Lime) 78 parts Titanium Dioxide 36 grams Silicon Carbide 21 grams Link to comment Share on other sites More sharing options...
neilestrick Posted May 20, 2014 Report Share Posted May 20, 2014 Yeah, somebody doesn't know how to write a recipe. I would start by trying it as is, like everything is in grams. You may find that you can get away with a lot less silicon carbide, but the numbers look like they should work as is. Link to comment Share on other sites More sharing options...

I was hopping somebody here had a good recipe of this glaze. Link to comment Share on other sites More sharing options...
neilestrick Posted May 21, 2014 Report Share Posted May 21, 2014 The silicon carbide is what makes it crater. Try adding it to other glazes. Link to comment Share on other sites More sharing options...
