Ahh I think I see what you are doing now

or do I
I found one that I pushed pretty far started to get actual plate movement of the cracks. It looks like it could be possible if taken further it starts to look like yours. I found that it was possible to let it sit for a while and then take it further. It looks like it has eventually created layers of different miosture level There may be some cay added to the inside. But in any event it looks like layers of cracked clay have fallen off.
You could get lost in this technique for years there are so many variables with it.
Your work always encourages me to find time to do some more.
How often are you getting a fired pot finished these days? do you use a small kiln. It made sense when mentioned that a small kiln enchorages experimentation. Even being able to fire one pot/piece at a time.
I get my first good glaze fire for this year in a couple of weeks. I hope I have some decent stuff to show off.
I had liked the horst style of crack pot with irregular cracks more than the obvious wheel thrown style but now I see there are so many inbetween.
With the bottom put in from the top the styles are limitless.

It's too bad your in such a hurry cause the stories I could tell you, Bushels and baskets of stories, hole crates full of stories. But if you can spare a moment I will tell you one story.
