Brush-on Glazes cone 4/6

We have 3 types of stoneware glazes: clear glazes; plain colored glazes; and reactive glazes. In general, clear glazes are used to cover designs created with underglazes. There is a choice of gloss, satin or crackle finishes. Our plain colored glazes are opaque and come in gloss and satin finishes. Some of our most popular stoneware glazes are the reactive colors which produce multi-tone and multi-colored effects by the combination of various metal oxides. Many other interesting effects can be created by layering these reactive glazes.

Spectrum Brush-on Glazes cone 9/10

Are all lead free and dinnerware safe 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 also similar in usage to the cone 4/6 reactive glazes but are for use at cone 9/10.

Spectrum Raised Accent Colours

Raised Accent Colors are slip-based colors (or engobes) which are available in 2 oz. applicator pens with a fine metal tip for decorating on greenware or bisque. They create embossed or raised designs on ceramic decorative work because the colors do not flatten out when they are fired. They are also available in 16 oz. squeeze bottles, which can be used to refill the pens or which can be used for slip trailing applications.

Crystal Glazes

Our Glaze Crystals are all lead-free and dinnerware safe when fired to a minimum cone 06. These crystals are very versatile and can be used successfully from cone 06 to cone 6. They can be used with any glaze in this firing range to produce a great variety of different appearances. They can also be intermixed. Many beautiful combinations of two or more colored crystals on your choice of glaze background can be used. Please be aware that, due to varying expansion coefficients, some of these crystals may cause crazing on some glazes, particularly at stoneware temperatures. Please test for suitability in your application.
