Clay Body Test using Red Clay and Neph Sye
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 …
It’s getting there…
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 …
Letting go…
A customer asked me yesterday if it’s hard to let favorite pieces go. Yes, sometimes it is. But there are always pieces like this one. It’s a native clay body, and it was on the …
Firing Cone 6 Glazes to Cone 10

Last Cone 5/6 Test
These maybe the last cone 5/6 tests that I do. I won’t say I’ll never return to cone 5/6 because who knows what the future holds. These were fired to cone 5. This is my …

This is the start of a journey, to fire hotter, in the hopes of not having to buy/ship as many ingredients. I’m also hoping to do less mixing and testing, thus, giving myself more time …
