Shino

The common reduction fired Shino glazes in North America are mostly gloss or semigloss, fat, white crackle glazes with some orange to red and dark red from iron in the clay body or iron slips under the glaze. Shinos were born in Japan as almost pure high fired feldspar glazes. Shino on porcelain requires underglaze iron bearing slips, or in-glaze iron (i.e. from an iron-containing kaolin). Shinos are fluxed with soda spars and nepheline syenite and do not contain calcium because it dissolves the iron and inhibits the red color. Shinos usually do not have added silica, the silica being contributed by the feldspars and the clays in the glaze. Some Shinos contain Spodumene, which may be added to balance the high expansion soda spars. A simple Shino recipe is 70% Nepheline Syenite and 30% Kaolin.
Shinos crawl, craze, and pinhole in ways that are often decorative and pleasing. Carbon trapping is common with Shinos. The trapped carbon leaves random dark, shadowy areas in the glaze.
People who use Shino glazes then to be philosophers!
