These lead free, non-toxic glazes
are food safe as long as there is a continuous vitrified surface when
fired. They are formulated to react during the firing cycle which
can product very interesting and beautiful effects. The final
appearance of the glaze is dependent on firing temperature, glaze
thickness and the clay body being used. The same glaze can look
quite different on different clay bodies, as it will react with
ingredients in the body. The samples shown on the colour charts
were fired in oxidation in an electric kiln. Different results
will be obtained in reduction.

1266 1267 1269) LEAD FREE, NOT NON-TOXIC. These glazes are lead free, but
they exceed the vanadium threshold limit in the liquid unfired state and
therefore are NOT Non-toxic. However they are all food safe if
fired to the proper firing temperature. They are
formulated to react during the firing cycle which can product very
interesting and beautiful effects. The final appearance of the
glaze is dependent on firing temperature, glaze thickness and the clay
body being used. The same glaze can look quite different on
different clay bodies, as it will reach with ingredients in the body.
