Simply a bump for a great thread.
I wanted to find the Chosera progression again and I had to dig. This had almost fallen off of the recent topics list.

Yes, those Chosera and Shapton progressions are great!

If you just want to find back a threat, the search function on this forum works great . (It's the tab "Search" above, not the search box in the top right. The latter one is for the entire site.)

I am still interested whether Clay found any more results regarding the ceramic stones.
