Learning About Envision Glazes

Basic Instructions
1. Apply to bisqaue fired to 1065°C (cone 04).
2. Apply 2-3 smooth, even coats.
3. Fire to 1000°C (cone 06).
4. Clean up with water.

Tips & Techniques
1. Envisions move very little during firing, so apply them with smooth, even strokes.
2. Envisions may be fired in a kiln used for leaded products, but it is best to separate leaded and non-toxic loads.
3. Most Envisions are overglaze compatible. Always refer to label instructions for proper application and usage.
4. Most colors may be mixed together to create custom colours with no changes in application or performance.
5. Envisions reds and greens can be fired simultaneously with no special precautions.

Health & Safety
1. Non-toxic and unleaded

Added Notes
The above information is recommended by the manufacturer. It should be noted the advice is offered when using this product with ware made from hobby slip, such as Excel Casting Slip or Auscraft Ultra Casting Slip. Envision glazes may be used with more traditional clays, but if applied to clay that is bisque fired to 1000°C (cone 06) and then refired to 1000°C (cone 06) glaze firing, crazing is almost certainly going to occur. We have found when used in schools this is not a problem. If glaze fit is essential refer to the firing range of the the clay. If the firing range of the clay states 1110-1270°C, the bisque firing should go to a point within this range, i.e. 1160°C (cone 3). This means the clay should be matured and when glaze fired to 1000°C (cone 06), crazing should not occur. Beware though, the porosity of the ware when going through a high bisque will be poor and the glaze layers will take much longer to dry!

Although these products are generally refered to as brush-on or paint-on glazes, best results will not be achieved if they are applied as one would paint when interior decorating. We recommend the use of a brush with soft hair, such as 6058 Flat Duster. The brush should be filled with the glaze and then applied by dabbing until the surface being glazed is covered. The glaze layer can then be smoothed and allowed to dry before adding a second layer. If this method is adopted probably only two coats would be necessary.

If a brush-on glaze dries in the jar add water to the jar sparingly. If the glazes has completely dried out a "fizzing" action will be produced. When the glaze has softened sufficiently, stir and apply as normal.
