The Spectrum Glaze Company is known for their superior quality glazes and their attention to safety. Spectrum glazes are available for low-, mid- and high-range firings and come in a variety of colors and textures. Spectrum glazes come ready for brushing, but can be watered down if needed, especially for spraying. Here at The Ceramic Shop, Spectrum Glazes are always on sale in our online shop and available in the following series:
100 Crackle Glazes (Cone 06-04)
After crackle glazes have been fired to cone 06/04 and allowed to cool, you can rub ink or dye into the cracks. This will make the crackle pattern stand out the way it does in the sample tiles. Although crackle glazes are lead-free and non-toxic, they are not dinnerware safe due to the porous nature of the glaze.
150 Low Fire Metallic Series (Cone 06-04)
Spectrum's Low Fire Metallic glazes should be applied in 3-4 coats of glaze. They are not reccomended for use on surfaces in contact with food.
200 Satin Glazes (Low Fire Cone 06-04)
Solid coverage with a smooth satin finish. Clear satin glaze should be applied thin to avoid looking milky. All other satin glazes should be applied 2 or 3 coats. All glazes are lead free and dinnerware safe. Sold in pints.
300 Majolica Series
Spectrum's 300 Majolica Series glazes can be used as a majolica, an underglaze, or as a glaze on its own. For majolica technique first apply a base white glaze, when the white glaze has thoroughly dried you can proceed to decorating with the 300 series colors. One coat will give you the traditional majolica look, and 2-3 coats will give a more opaque look. For use as an underglaze, simply apply 1-3 coats of the color of your choosing and then cover the entire piece with clear glaze. The 300 series Majolica Colors can also be used as a glaze on its own, over a wide temperature range from cone 06 to cone 6. It will fully vitrify at cone 06 but the surface will not be quite as shiny as Spectrum's 700 series glazes. At cone 6 most of the colors will show little color change, except the pinks and purples, which are not quite as temperature stable. Using a zinc-free clear glaze will improve results at stoneware temperatures. All of the majolica/ultraglaze colors are lead-free, dinnerware safe and A/P non-toxic.
700 Opaque Glazes (Low Fire Cone 06-04)
Includes glossy bright colors with solid opaque coverage. Apply 2 or 3 coats for best results. All glazes are lead free and dinnerware safe. Glazes sold in pints.
800 Semi Transparent Glazes (Low Fire Cone 06-04)

850 Raku Glazes (up to 1600 degrees F)
Designed for firing in electric or gas kilns. Different raku techniques will yield different results. Raku glazes are lead free. Sold in 4oz containers.
