Absorption testing trials and tribulations
Well, my last tests did not go well. One test bar (the sandy one with 16% absorption without anything added) was way over fired at 30% neph sye. It still had 11% absorption at cone …

I know it probably seems like I haven’t been working because I haven’t been posting. I have been working—it’s just the boring behind-the-scenes stuff. Since the disaster in April, where my clay got contaminated, I’ve …
The one marked RC is my reclaim. It’s a mix of commercial and local materials. I have no idea of the percentage of each, as it all gets mixed together. Absorption at cone 7 is …
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 …
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 …
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.
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. …
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. …
I haven’t been very good at keeping track of my clay tests recently. I need to blog about these as a way of keeping up with what tests I’ve run and what needs to be …
The reason I decided to switch to cone 10 reduction vs cone 6 oxidation was to limit the amount of materials I have to buy (and ship) and to reduce the amount of physical labor …
