Well some progress…and some disappointment…

Moving back to cone 6
After trying working with my deep red clay at cone 9/10, I am moving back to cone 6. At least for the time being. I knew when I moved to cone 9/10 that I might …
More working with the silty clay
This is the batch I dug a few days ago and processed half of it to see if I can recreate the accidental perfect batch. I posted a few days ago. I kept it a …
100% Local Clay Body

Sandstone Clay Cone 10 Oxidation
This test was done Feb 2022, and I never created a blog post. Almost cone 10 in oxidation. 100% local clay. This clay froze and was a bit stiffer than I’d like. Previous workability tests …
