Sheffield Pottery offers a wide array of Spectrum 700 Series Low Fire
Opaque Gloss Glazes. With more than 50 shades, every artist can easily
find the perfect glaze for their next project.
These opaque glazes are made to work together without bleeding. This
allows for multiple colors and clear designs when firing, especially
when applied in a thick covering. Conversely, the clear gloss glazes in
this series should be applied thinly in order to avoid fogging.
Spectrum 700 Series Low Fire Opaque Gloss Glazes are popular for
classrooms because they are completely non-toxic, lead-free, and
CLEAR GLOSS GLAZE
700 - An excellent lead free, dinnerware safe, A/P non-toxic clear
glaze, which is compatible with most commercially available underglazes.
It has good tolerance for a wide variety of low fire pug clay bodies
and rarely crazes. It was designed specifically for pugged clays, and
therefore should be tested before being used on castware due to the
potential difference in coefficient of expansion. If you are looking
for a clear glaze designed specifically for castware, consider trying
our 400 Clear or 800 Clear. We recommend applying clear glazes thinly
(i.e. 1 to 2 coats by brushing) as it may cloud when applied too
OPAQUE GLOSS GLAZES
701-763 - A wide range of lead free, dinnerware safe, A/P non-toxic
colors, including excellent bright primary colors. These glazes require 2
to 3 coats by brushing for opaque coverage. In general, a more even
appearance can be achieved by alternating the direction of brush strokes
by 90? to the previous coat (i.e. first brush up and down the piece,
next coat brush side to side). These glazes do not bleed together very
much so they can usually be butted against each other without the colors
running. We have deleted the following colors from this series: 719,
720, 722, 725, 728, 729, 733 & 739. We have added colors 752 to 763.
