What makes a glaze glossy?
For the glossy glaze, the ratio is 8.98 molecules of SiO2 for every molecule of Al2O3. It’s this ratio that determines whether a glaze is likely to be matte or glossy. As the SiO2:Al2O3 ratio goes up, a glaze will move from matte to glossy.
What happens if you apply too much glaze?
Applying glaze too thinly can result in rough glazes and can affect the glaze’s color. Applying glaze too thickly can cause the glaze to run off the pot, weld lids to pots and pots to kiln shelves, and can result in blistering. Applying glaze unevenly may result in splotches and streaking in both color and texture.

What can I use instead of glaze?
