ComaT10 in Browse Member Galleries 3 Posted August 14, 2016 · Report reply 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.
