You can change the ratio of these ingredients to suit your individual
needs and tastes, within certain parameters. The more frit you use
(relative to the other ingredients), the lower will be the maturing point of
the glaze. The more silica you use (as mentioned earlier), the less the glaze
may tend to craze, but the fewer the crystals you will produce. You can
see from the composition of zinc silicate, Zn2SiO4, that for every two
atoms of zinc oxide, we need one of silica to get a crystal molecule. Aside
from the silica that is needed for the crystals, additional silica is needed for
the glaze itself; so one must make sure one has enough. Raising and lowering
the amount of zinc oxide in a glaze will directly affect how many
crystals the glaze will be able to grow. Adding additional oxides/carbonates
such as those of titanium, calcium, tin and so on will affect opacity,
crystal size and shape, ancillary development and color.
