Buying Guide: Key Considerations For Choosing Mother Of Pearl Overglaze
- Firing Requirements: Most overglazes require a secondary firing at a lower temperature. Confirm your kiln schedule and glaze compatibility to preserve the pearlescent effect.
- Size And Usage: For small projects, 25 g bottles are often sufficient. Larger projects may justify 100 g containers for value and coverage.
- Base Glaze Compatibility: Overglazes are applied over already glazed and fired ware. Check that your base glaze’s finish will support the luster without dulling the effect.
- Application Method: Brush-on ease varies by brand. If you’re new to overglaze, look for products labeled as easy application with clear drying and refiring steps.
- Color and Intensity: Pearl luster intensity can vary with the underlying glaze. If you want a bold effect, select a product known for deeper iridescence or plan a test swatch.
- Packaging Notes: Some bottles may appear not fully filled due to packaging design. Verify the stated content before use to avoid unexpected shortages.
- Safety and Compatibility: Use with appropriate ventilation and follow manufacturer guidelines. Some products require kiln firing versus kitchen-oven use for safety and performance.
