Raku Glaze Recipe Of The Day

I thought it would be a good idea if I not only documented my glaze recipes but also share them with anybody interested. Not sure If I can stick to a recipe a day but we shall see.

This used to be my favorite raku glaze when I was attending Bemidji State University. It produces a semi-dry sandy textured surface that flashes, especially when quickly reduced. The container lid is lifted, fanned and resealed , "burped," to promote more brilliant flashing. Once a nice flashing is obtained , the pot is dunked in cold water to freeze the colors.
