Spectrum 700 Series Low Fire Opaque Gloss Glazes
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 dinnerware safe.
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 heavily.
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.
