Description: CALCIUM ZIRCONIUM SILICATE
Was used in high fire glazes as the sole opacifier. It can be blended with other zirconium products for special finishes.
It is no longer manufactured.
This was an ideal opacifier for use in chrome-tin pink and maroon glazes since the calcium enhanced the development of the color.
Opacifiers are powders that turn transparent glazes opaque by various chemical and physical mechanisms (and combinations of mechanisms).
