What is white?
If we were after a white we would test many porcelains with a variety of opaque white and clear glazes. Grolleg over tile-6 kaolin? Would we be after the creamier side of white or the blue side of white? When we dropped these pieces off yesterday we saw the porcelain works the Jingdezhen clay artists shipped over from China. Those pieces were glazed with a very pale ice blue transparent celadon glaze. The Chinese pieces were definitely sweet in color and smooth. High fired in a gas kiln makes a huge difference in a glaze. There is something about the melt between clay and glaze at over 2300 degrees F that just does not happen the same with mid-range electric firings. But there are qualities at mid range electric firings that you just can't get in high fire gas. Which is why we do both.
Do we like white pots? Do we want to try to glaze some of our pots white? Probably not. But I do think we may pull out our bucket of ice blue celadon and try mixing up a few more celadon glazes in the future.
