High Fire Glaze

High Fire Glaze Example


Chrysanthos High Fire Glazes add color and gloss to ceramic ware in a single step. A large range of colors are available, they are all lead-free and depending on the color are translucent, semi-opaque or opaque in their coverage. They provide a beautiful and practical means of giving solid color coverage to broad areas or for highlighting decorative or incised ware.

High Fire Glazes are for application to bisqueware and when fired correctly will seal and protect the ceramic ware from moisture and discoloration caused by contact with food and liquids.


Three full coats required to achieve the best results. These are carefully applied at right angles to one another (ie. crosshatched), allowing each to dry in-between. A soft glazing brush should be used in order to minimise streaking. Besides brushing, High Fire Glazes may also be sponged.

High Fire Glazes are suitable for use in controlled glaze effects, for majolica techniques and are overglaze compatible.

High Fire Glazes may be sprayed and thinned with clean water if necessary to improve glaze flow.

High Fire Exotic Glaze


Chrysanthos High Fire Exotics are a range of glaze varieties aimed more at the sophisticated user. The glazes produce more striking results due to their compositions. Within the range are the following groups of products:

a) Metallic Glazes group HE001 – HE005
b) Variegated Glazes group HE101 – HE153
c) Low Sheen Glazes group HE201
d) Crackle Glazes group HE301


Generally, to obtain optimum results, 3 – 4 coats of the metallic glazes and 2 – 3 coats of the other glazes should be applied using a fully loaded brush. Ensure each coat is dry before applying subsequent coats at right angles to each other.

With the variegated glazes, different effects will result based on the thickness of the glaze on the surface of the body, ridges present in the clay body were pooling of glaze can occur, clay body used and firing temperature.

Custom variegated glazes can be created by mixing oxides and other raw materials with the HE101 Clear.
