Shino glazes were first created during the Momoyama period (1573 - 1615) in Japan. Several types of shino glaze were developed exhibiting different colours and surface textures. They often have a dimpled surface texture like lemon skin or even 'crawl' away from the clay body revealing patches of unglazed clay. While such an organic, irregular surface is part of a Japanese aesthetic and was highly prized for tea ceremony wares it may be seen as a defect in the west where a perfectly even glazed surface is commonly expected in functional ware. A common variety of shino is a thick white glaze with the appearance of snow. It is thought this type of shino was a result of the desire to emulate the surface of a pure white clay body known as porcelain, which had been discovered in China.

Carbon Trap Shino Glaze
A type of glaze now known as American shino was developed in the early seventies by Viginia Witt, who, as part of a project set by the University of Minnesota to try and replicate early Japanese glazes, was the first to add soda ash to a shino type glaze. When fired in the reducing atmosphere of a gas kiln as the soda ash melts it traps the carbon from the atmosphere of the kiln resulting in the grey and black speckling of the glaze and also accounts for the peach coloured bloom.
I adapted the glaze used on these porcelain vessels substituting American with Australian ingredients.
Southern Ice Porcelain
These vessels are constructed from translucent Southern ice porcelain fired to 1280°C in reduction in a gas kiln.
