Setup and Preparation

1. Preparing the Glaze:

• Ensure the glaze is thoroughly mixed before use. Stir gently to avoid introducing air bubbles.
• If the glaze appears too thick, a small amount of distilled water can be added, but do so sparingly to maintain consistency.

2. Preparing the Bisque Ware:

• Ensure your bisque ware is clean, dry, and free of dust or debris. Wipe with a damp sponge if necessary and allow to dry completely.
• Handle bisque ware carefully to avoid transferring oils from your hands, which can affect glaze adhesion.

Operating Instructions

1. Application:

• Brushing: Apply 2-3 even coats of glaze using a soft brush. Allow each coat to dry to the touch before applying the next.
• Sponging: For textured effects, apply glaze with a sponge. Multiple thin layers may be required to achieve desired opacity.
• Combination: This glaze can be used in combination with other glazes. Test combinations on a sample piece before applying to your final work.

2. Firing:

• Temperature Range: Fire the glazed piece in a kiln between cone 6 (approximately 2232°F / 1222°C) and cone 10 (approximately 2345°F / 1285°C).
• Atmosphere: Suitable for both reduction and oxidation firing environments.
• Kiln Loading: Ensure glazed pieces do not touch each other or the kiln shelves, as the glaze will melt and adhere during firing.
• Cooling: Allow the kiln to cool naturally and completely before opening to prevent thermal shock to the ceramic pieces.

Maintenance and Care

1. Glaze Storage:

• Store the glaze in its original sealed container in a cool, dry place, away from direct sunlight and extreme temperatures.
• Ensure the lid is tightly sealed after each use to prevent drying out.

2. Tool Cleaning:

• Clean brushes, sponges, and other application tools immediately after use with warm water.
• Allow tools to dry thoroughly before storing.

Troubleshooting

Common Issues and Solutions:

• Uneven Glaze Application: Ensure bisque ware is clean and dry. Apply glaze in thin, even coats, allowing each to dry. Stir glaze thoroughly before and during use.
• Pinholes or Bubbles: May be caused by too thick an application, insufficient drying time between coats, or impurities in the bisque. Ensure proper drying and clean bisque.
• Glaze Running: Applying too many coats or firing at too high a temperature can cause glaze to run. Reduce coat thickness or verify kiln temperature.
• Dull or Matte Finish (unexpected): Could be under-firing or incorrect kiln atmosphere. Verify firing schedule and kiln conditions.
