Bone dry, garden clay bowl.

The clay looks good.
No signs of cracking in the thrown body or where the thrown foot meets it.
So, fingers crossed as I head to the next stage: bisque fire.

If you want to support me, please look at the right hand column.
Consider BUYING one of the books. (I've read them all, and I do recommend all of them). Also at the bottom you can"join this site" to give me a warm fuzzy feeling that you are reading, looking and enjoying my adventures with clay..

Oooh, I'm envious!

My added grog reduced/eliminated the cracking, but the clay shrank around it, giving the pots a surface reminiscent of cottage cheese. Red cottage cheese, to be exact.

Now trying to figure out how to crush the grog to a finer mesh size...

Dear Fiona,
What a frustration for you.
If you crush the grog, it won't be grog.
I think my clay is OK just out of the ground, but I think it's melt point was a bit close for my liking (I'm firing it to ^10)'
After reading your first comment (thank you so much) I did some research. It does suggest grog as a re idly, but also kaolin. I chose to use kaolin because that is what the main ingredient of porcelain is, it also raises the melt point.
I look forward to hearing more from you (I read your blog, you write beautifully. I read with delist.).
