Test? Where you gonna get Ocmulgee?
Jim that was 25 years ago but I have some Blackjack clay from east Texas that might be an interesting test. It's a natural clay with a lot of fine sand and the red art might make it smoother to turn, otherwise I'll use Sagger.
I believe you are in Georgia, right, you have some LIzella that might make for an interesting test with red art.
I'll mix up a small batch next week after I get the kiln loaded and going.
Yes, I live in Lizella. Ocmulgee was dug on the Ocmulgee River that runs through Macon (10 miles away) and was very similar to Lizella Clay which is dug on the Echeconnee which runs into the Ocmulgee. Lizella Clay is still available.
