Chrysanthos Color Co. Ltd. Hobby Glazes are specifically formulated for application and firing on white clays used in the hobby ceramic industry. The colored appearance of the Hobby Clear Glaze is intended to assist application by highlighting glazed areas.
When fired correctly, the Hobby Clear Glaze will seal and protect ceramic ware from moisture and discoloration caused by contact with food and liquid. The Hobby Clear Glaze also enhances Underglaze, One Stroke and Café Colors over which it has been applied.
Any Underglaze, One Stroke or Café Color decoration that has been applied on bisqueware should be dry before being glazed over using Hobby Clear Glaze.
To obtain optimum results, 2 – 3 coats of glaze should be applied using a well-loaded glaze mop brush. Ensure each coat is dry before applying subsequent coats at right angles to one another (i.e. crosshatching).
For glazing the interiors of hollow-ware a “roll glazing” technique is used. The glaze is diluted with 33% clean water to 67% glaze (1:3), poured into the vessel to be glazed and slowly rotated to ensure all interior surfaces are coated before draining.
The remaining diluted glaze may be reserved for future roll glazing application provided it is stored in an air-tight container and properly stirred before re-use.
The interior of vessels should always be glazed before the exterior to avoid over-handling and more importantly to avoid the possibility of damaging the external glaze.
Hobby Glazes are also available in dipping versions. To dip, ensure that any decoration that has been applied to the bisqueware is dry. Stir the glaze thoroughly and to one litre of glaze add 400 – 500 ml clean water. Proceed to dip pieces once using tongs, stirring glaze occasionally to keep the glaze uniform.
Note: The application of lead-bearing glazes by spraying is not recommended.
Due to its high porosity, hobby earthenware intended for the storage of food or beverages should be entirely glazed with Hobby Clear Glaze and stilted for glaze firing, rather than dry footed. This will eliminate the risk of moisture absorption and bacterial growth into the porous earthenware body.
The Hobby Glazes should be fired between cone 06 (999°C) cone 04 (1,060°C) to produce a clear glossy finish on bisque that has previously been fired between cone 04 (1,060°C) and cone 03 to (1,101°C).
Chrysanthos Color Co. Ltd. Hobby Glazes when used with appropriate precautions are non-toxic however it does contain lead bi-silicate.
Ceramic ware that has been coated with Hobby Clear Glaze, should not be used for the storage of food and beverages if it has crazed or not been fired correctly (cone 06 to 04).

Chrysanthos Superior Clear Glaze is a lead free clear glaze that has been specifically designed as a replacement for Hobby Clear Glaze. The color response as such is very similar to that achieved by using a leaded glaze.
Available in brush on and dipping versions, they can be used on earthenware bisque that has first been decorated with one of Underglazes, One Strokes or Cafe Colours. Once fired correctly, the Superior Clear Glaze will protect the ware from moisture and discoloration caused by contact with food and liquids.
The coloured appearance of the brush on Superior Clear Glaze is intended to assist application by highlighting glazed areas.
Depending on the firing temperature two or three full coats are required to achieve the best results using the Superior Clear Glaze Brush on. The coats 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, the Superior Clear Glaze may also be sponged.
The Superior Clear Glaze Brush on may be sprayed and thinned with clean water if necessary to improve glaze flow.
When using the Superior Clear Glaze Dipping , it may be necessary to add some clean water depending on the thickness of the glaze required on the ware and the firing temperature of the kiln. Stir the glaze thoroughly and to 10 litres of glaze add 400 – 500 ml clean water. Proceed to dip pieces once using tongs, stirring glaze occasionally to keep the glaze uniform.
Both the Brush on and the Dipping Glaze are overglaze compatible.
The Superior Clear Glaze has been specifically formulated for low fire earthenware clay that has been earthenware bisque fired between cone 04 (1,060°C) and cone 03 (1,101°C) then gloss fired to between cone 07 (984°C ) and cone 03 (1,101°C).
