Crater Test Series
Here are some Crater Glaze Tests with stains.
The recipe is Pinnell Strontium Matte at cone 6 E1 firing
60 Nepheline Syenite
20 Strontium Carbonate
1 Lithium Carbonate
10 Ball Clay–Old Mine #4
9 Silica
100 Total
Additives
5 Titanium Dioxide
2.5 % Silicon Carbide 600 M
Apply VERY thick. And you can add up to 5% silicon carbide. You can also vary the amount of stains. See page 178 in The Complete Guide to Mid-Range Glazes for more recipes and firing information. Electric E1 cycle. This can vary too!!
This last one is Mason 6433 at 5%, 10%, 15%, 20%, and 25%

so one last question, if you dont mind….
---do slow ramp down between 1900 and 1500 for a matt effect? (Am working with Steve’s Strontium C6 glaze from Lana Wilson’s book.)
Have been successful in getting a cratered look by heavily texturing the pot when throwing and not quite covering everybody up.
Feels a bit like a cheat though. Hence this new path down crater glazes.
concerning the silicon carbide, you wrote 600M.
Is it the grain size ?
And where do you buy it. I found on eBay a Grit-400 (grain size) silicon carbide from England by Minerals Water.
By the way I am from France.
Thank you for your answer.

Do you remember if you included the additives in your tests? I'm very into the textures and craters, but I'm not sure if I should include the titanium dioxide or the silicon carbide. Thanks!
Thank you
