ZrO2 (Zirconium Dioxide)
ZrO2 reduces the thermal expansion of a glaze (although not by the same mechanism as other oxides that impose their expansion by going into solution in the glaze melt). Thus its contribution to the calculated thermal expansion of a glaze may differ unexpectedly from what it actually does in the kiln. ZrO2 reduces glaze melt fluidity, both ...
