This glaze and most other shino type glazes are dependent upon claybody, thickness of application, length of time from glazing to firing and reduction. Generally this glaze will fire toasty brown where thin to a creamy, blushing white where thick and will crawl where very thick. Under certain high reduction conditions this glaze might fire to a gold luster finish.

This glaze and most other shino type glazes are dependent upon claybody, thickness of application, length of time from glazing to firing and reduction. Good Carbon Trapping with reduction starting at about 1645F. This glaze can vary greatly with time between glazing and firing. Use wax to stop the migration of the soda ash to the surface during drying to create areas of less carbon trapping. This glaze has many faces so I encourage lots of experimentation.
