Black Matte Ceramic Glaze Formulation for Sanitaryware/Tableware

Black matte glaze in sanitaryware is one of the most challenging finishes to achieve consistently. The final appearance depends heavily on the firing curve, oxidation conditions, and raw material interactions.

This article provides a base formulation that can be used as a starting point for developing a stable black matte glaze. Further fine-tuning is required based on plant conditions.

Key Development Considerations

• Maintain consistent firing temperature and soaking time.
• Control oxidation conditions carefully during firing.
• Adjust zircon content to control matte effect.
• Fine-tune stain percentage for depth of black shade.
• Monitor glaze thickness during application.

Conclusion

This formulation should be used as a starting base for developing a black matte glaze in sanitaryware applications. Due to variations in raw materials and kiln conditions, it is essential to perform plant-level trials and optimize accordingly.
