The recipe amount of zircon used for glaze opacification and whitening is usually less than 15% of the batch weight, sometimes much less. Where other light-scattering crystals also form in the glaze, 3–5% zircon may be sufficient. While zircon is exceptionally effective as an opacifier, it can be problematic when added to glazes used on ...
