Zircon

Zircon sand (which is milled to produce zirconium silicate powders) has become so expensive that major manufacturers are considering, or are already diluting their products with other materials (like kaolin). So 'heads up' if your glaze is not as opacified as it was before! Also, use care in pretesting zircon materials, they vary in quality.

Zircon - Wikipedia

Zircon (/ ˈ z ɜːr k ɒ n / or / ˈ z ɜːr k ən /) is a mineral belonging to the group of nesosilicates. Its chemical name is zirconium silicate, and its corresponding chemical formula is Zr SiO 4. A common empirical formula showing some of the range of substitution in zircon is (Zr 1–y, REE y)(SiO 4) 1–x (OH) 4x–y.
