Mayco Elements Opaque Glaze features beautiful natural earth tones. Designed to mature at cone 06-05. Apply 2-3 coats to shelf cone 04 bisque, allow to dry between coats. As movement and flowing are characteristics of these glazes, taper off toward the bottom of the ware to prevent glazes running off the piece onto kiln shelves. Can be fired at higher temperatures but will change in appearance. Testing is recommend prior to use. Food safe when fired. Freeze/Thaw stable.
