“Red Tenmoku”

(11 October, 2004)

Here is a Red Tenmoku bowl, fired to cone 10r. The bowl is about 6" across. It is made of Loafer’s Glory, from Highwater Clays; the glaze consists of Brick Clay from western Wisconsin; Wood Ash (Oak, unwashed); and Red Iron Oxide (84% purity). I strongly suspect that the yellow teadusty or “corn-pollen” sprinkles, which show up particularly well on the interior, result from the ~2.6% MgO content of the Brick Clay; I get essentially the same effect in other iron-rich glazes if I add enough Mg. Oddly, although all or nearly all of the ancient Chinese high-iron Jianware glazes contain noticeable MgO, very few modern Western “Tenmoku” glazes seem to use magnesium. Go figure.

(Click any of the small photos to get one that is 1024x768 px. If you want something even larger, you can change the “.10c.” in the filename of the large image to “.22c.” for the full-size originals, 2272x1704; just be aware that those files are about 1.5 MB each, and will take a while to download.)

This bowl was donated to a benefit auction.
