Awhile back there was a refrence to FF413 being better on porcelain and FF644 better for stoneware. I am using a Plainsman clay body H570 (white plastic stoneware). I am wondering if 644 just needs a higher temperature on the clay I'm using than 413 or wether the 644 is actually a better fit for stoneware than 413?
I'm firing to a top temp of 2340F and have been having problems with pinholing on the rims and upper sections of my pots. I was thinking that the liner glaze was the problem but now wondering if it more likely the clay body as the pinholing is definatley worse with glazes made with FF413.
I'm curious what you think.
Thanks, Lance
