This glaze is perfect for potters who want a beautiful and dependable finish without fussing over complicated formulas or hard-to-find materials.

Ingredients

• 60% Feldspar (Potash or Sodium Feldspar) – Acts as a flux to melt the glaze at cone 6.
• 20% Silica (Quartz) – Provides durability and hardness to the glaze surface.
• 15% Kaolin (China Clay) – Adds alumina for glaze stability and suspension.
• 5% Whiting (Calcium Carbonate) – Helps with melting and smooth gloss.
• Optional Colorants: Add 1-3% of cobalt oxide for blue, copper carbonate for green, or iron oxide for earthy tones.
• Water: Enough to create a smooth, brushable slurry (approx. 50-60% by weight).

Equipment

• Digital Scale: For accurate weighing of dry materials.
• Mixing Container: Large bucket or plastic tub for blending glaze slurry.
• Electric Mixer or Drill with Mixing Paddle: To thoroughly blend the glaze.
• Sieve (80-100 mesh): To remove lumps and ensure a smooth consistency.
• Brushes or Spray Gun: For glaze application.
• Gloves and Dust Mask: Safety gear while handling dry materials.
• Test Tiles or Bisque Ware: For testing glaze results.

Instructions

1. Weigh Out Materials: Using your digital scale, carefully measure each dry ingredient based on the percentages listed above. For example, for a 1000g batch, use 600g feldspar, 200g silica, 150g kaolin, and 50g whiting.
2. Mix Dry Ingredients: Combine the dry powders in your mixing container and stir thoroughly to ensure even distribution.
3. Add Water Gradually: Slowly add water while mixing continuously until you achieve a smooth, creamy slurry consistency that brushes easily but is not too runny.
4. Sieve the Slurry: Pass the glaze through an 80-100 mesh sieve to remove lumps and undissolved particles. This step is crucial for a smooth glaze surface.
5. Add Colorants (Optional): If you want colored glazes, mix your chosen oxides or carbonates into a small portion of glaze slurry first, then blend back into the main batch to ensure uniform color.
6. Apply the Glaze: Use a brush or spray gun to apply 2-3 even coats over bisque-fired ware. Allow each coat to dry before applying the next.
7. Fire to Cone 6: Load your kiln and fire to cone 6 (2232°F or 1222°C) following your kiln’s recommended ramp and soak schedules.
8. Cool and Inspect: After firing and cooling, check your pieces for glaze coverage, texture, and color. Note any adjustments needed for your next batch.

Tips & Variations

“Always test your glaze on sample tiles before applying it to your final pieces. Glaze behavior can vary based on clay body, firing atmosphere, and application thickness.”

• Adjusting Glossiness: To increase gloss, increase the feldspar slightly or add a small amount of frit 3134.
• Matte Finish: Replace some feldspar with more silica or add a small portion of alumina hydrate to dull the surface.
• Color Play: Experiment with layering different colorants to create variegated effects. For example, a thin cobalt blue topcoat over a clear glaze can add depth.
• Texture Variation: Add fine grog or volcanic ash to the glaze mix for a textured finish, great for rustic pottery.
• Application Tips: For even coverage, spray application often yields better control over thickness than brushing.

Nutrition Facts

While glaze recipes aren’t consumed and therefore don’t have nutritional content, it’s important to handle all raw materials with care. Many oxides and carbonates can be toxic if inhaled or ingested, so always wear a dust mask and gloves when mixing dry powders.

Serving Suggestions
