bucket. Simlar problem with BlackJack Clay
Mel, others who may have used or are currently using Black Jack Clay
(you to David.) Mel's comment about the dense "frit like" substance at the
bottom of the throwing bucket made me think about a similar substance that
forms, at times, with Black Jack. I'm not really sure what it is and I love
the clay. It has a sand like consistency and seems to interfere with the
reconstitution of the clay when I attempt to "recycle". Has anyone else had
this problem?
Thanx

I have not observed the particular problem you speak of, but I've had
lots of trouble with my recycled porcelain getting tiny bloats or blebs in it's fired
state. The only comment I've ever come across is this one from Hamer in the section
on porcelain " When scraps of porcelain body are reconstituted there is sometimes
a problem of bloating at a previously satisfactory temperature." Any thoughts?
I well remember the article in CM on Black Jack clays, and I've been
envious of the lucky potters who get to use these clays ever since.
How can I get ahold of some?

David, just give them a call. They are located in a small town in East
Texas. The phone number is (903)469-3322. David Hendley can give you the
full skinny on the mud. He's the one that wrote the article.
