Initial Melting Point: 1050°C
Applicable Temperature: 1150°C–1200°C
CTE: 160
High initial melting point, excellent whiteness, reduced glaze pinholes, and softer glaze surface. Low CTE perfectly matches high-silica bodies, minimizing crazing risk—especially for large-format slabs and outdoor tiles. Alumina-calcium synergy provides exceptional thermal shock resistance. Calcium promotes micro-crystallization, forming a fine matte surface without post-polishing. For large slabs.

Floor Tile Polished Glaze Frit is optimized for high-efficiency tile production lines, maturing in just 45 minutes (vs. 2 hours for standard frits)—a game-changer for manufacturers aiming to increase output. Its low-melting formula (1050℃ peak temperature) integrates lithium oxide (2%, for rapid sintering) and potassium oxide (5%, for fluxing), reducing the total firing cycle (from room temperature to cooling) to 2.5 hours. The frit maintains a glossiness of 85 GU and Mohs hardness of 6, ensuring durability matches standard frits. It has a particle size of 150-250 mesh, ensuring fast dissolution in glaze slurries and uniform coverage.
Production Efficiency: Cuts firing time by 60%, increasing factory output by 40%—a 100m tunnel kiln can produce 12,000㎡ of tiles per day (vs. 8,500㎡ with standard frits).
Energy Savings: Reduces fuel consumption by 25% per square meter of tile (from 0.8kWh/㎡ to 0.6kWh/㎡), lowering carbon emissions and operational costs.
Consistent Quality: Minimal color and gloss variation (<ΔE 1.0, <3 GU) across production batches, thanks to strict quality control (particle size variation <10%, chemical composition variation <2%).
Line Compatibility: Fits seamlessly into existing spray-glazing and tunnel kiln systems—no need for equipment upgrades, reducing capital investment for manufacturers.
Application Scenarios: Large-scale tile manufacturing plants (producing 50,000+㎡/month), quick-turn construction projects (e.g., residential complexes with tight deadlines), and commercial tile suppliers with high order volumes.
Operation Guidelines: Mix the frit powder with deionized water (1:0.8 weight ratio) and 0.6% CMC—stir at 1000 rpm for 8 minutes to form a slurry (viscosity: 1600-1900 cP). Spray-glaze at 0.45MPa pressure, applying a single 0.3mm thick coat. Fire in a tunnel kiln with a ramp rate of 5℃/minute (faster than standard 3℃/minute), peak at 1050℃ for 10 minutes, then cool at 10℃/minute to 600℃, then natural cooling.
Q: Does fast firing affect glaze durability?
A: No—laboratory tests confirm it maintains Mohs hardness 6 and 85 GU glossiness, with abrasion resistance (Taber test) and chemical resistance matching standard frits. The lithium oxide ensures full sintering even at low temperatures.
Q: Can it be used with existing production equipment?
A: Yes, it is compatible with most spray-glazing machines (e.g., Krones, SACMI) and tunnel kilns. We provide a custom firing curve for each kiln model to optimize results.
Q: What’s the maximum tile size it can coat?
A: Up to 1200x2400mm without edge runoff—for larger tiles, use a dual-nozzle spray gun to ensure even coverage and reduce drying time between sections.
Q: How to adjust for different tile compositions?
A: Test with 5kg samples first—for porcelain tiles (high alumina), keep the frit ratio at 30% of the slurry; for ceramic tiles (lower alumina), increase to 35% to improve adhesion. We offer free sample testing for customers.
Q: What if the kiln temperature drops below 1050℃?
A: A temperature drop to 1020℃ will reduce glossiness to 75 GU and hardness to Mohs 5.5—if this occurs, increase the peak hold time to 15 minutes to compensate. For drops below 1000℃, the glaze will not melt fully, and tiles must be reworked.
