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 …

Digging Clay
In my last post (the clay with 0.3% absorption at cone 9 oxidation), I mentioned it comes from a low spot on top of a hill. Well, here it is.
100% Local Clay Body
This clay comes from an odd low spot, on top of a hill on our land. Right out of the ground, it’s very silty and not plastic enough to throw, fires to above cone 8. …
Light Clay Body Test #1
This body uses one of my lighter colored clays. It’s probably more than 50% sand right out of the ground, however, it’s very easy to process, settles out of a slurry wonderfully, and de-waters quickly. …

First Firing of the TDI Conversion Down Draft
Pretty pleased with the results. This is 100% Moon Clay (dug in Moon, Oklahoma), except for the one pot that slumped. That clay was from beside my house. The Moon clay has 8.2% absorption at …
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 …
Moon Clay Oxidation Test Cone 10
This is the Moon Clay (Moon, Oklahoma) fired to cone 10 oxidation and cone 10 reduction (the bar). Absorption (3 hr boil 21 hr soak) is 8.2%. It’s an interesting clay to work with. It’s …
Another High Fire Test
EDIT: Fired porosity tested as 2.8%. That’s about perfect as I can fire a bit hotter, and it gives me a bit of wiggle room for reduction. Just out of the kiln this morning. Cone …
