Are you satisfied with the T10 coma crystals? I think the crystal color looks more appealing in the Coma clay. It looks much more vibrant imo. The background looks more peach colored compared to the big tile which seems more brown, but it could just be angle of light.


Interesting stuff.

Joseph: yes I am in fact: usually I am not. Only thing I need to do is dial in the ramp hold temp to produce round floret crystals. T10 is a tank, the tile did not warp, which is common with standard porcelain. There is a distinct difference in field color as you noted: the standard cone 10 has much higher iron content. Going to throw some V-gum in and send you down a batch to play with. More than curious to see how your celadon works on it.
