High Opacity
Opaque Frits
Full-body opacity for complete surface coverage. ZrO₂-based formulations deliver consistent whiteness and hiding power in compatible glaze and firing systems.

Frits
The Foundation of Every Ceramic Glaze
Precision-formulated glass compositions engineered
for performance, consistency and creative possibility
01
The Material
What are Frits?
Frits are technical glasses produced by fusing raw materials at high temperature, then rapidly quenching to create chemically stable, homogeneous compositions. They are the primary functional component of ceramic glazes.
Built on the parent companies’ 30+ years of expertise in frit manufacturing, INCA Ceramics in Morbi, Gujarat produces a comprehensive range of frit types from opaque to transparent, glossy to matt, each engineered to meet exact performance and aesthetic specifications for the global ceramic tile industry.

Product Range
Engineered for every
application
Optical Clarity
Transparent Frits
Crystal-clear glass compositions for depth and brilliance. ZnO/Na₂O/K₂O systems engineered for maximum transparency and glaze clarity.
Low Sheen
Matt Frits
Controlled matting through precise crystallisation. CaO/MgO/BaO/SrO systems produce consistent low-gloss surfaces with refined tactile quality.
Custom
Special Frits
Custom-engineered formulations developed for specific applications. Confidential compositions tailored to your unique processing and aesthetic requirements.
03
Applications
Where our frits
perform
01
Ceramic Glaze Manufacture
The primary application. Our frits serve as the functional glass component in wall tile, floor tile, GVT and porcelain glaze formulations.
02
Printing Powder Production
Specially formulated frits ground to fine powders for digital and screen printing applications on ceramic tile surfaces.
03
Granilla Manufacturing
Our frits are the base material for INCA's own granilla production line, creating precision-sized glass grits for advanced surface textures.
04
Technical Properties
Built for precision
High-Temperature Stability
Select the firing window by grade and validate it against your kiln cycle
Controlled Fusibility
Precise melting behaviour for predictable glaze flow and surface development
Chemical Resistance
Assess chemical resistance on the fired glaze under the conditions required for its application
Batch-to-Batch Consistency
Quality control targets consistent composition and processing behaviour from batch to batch
Wide Opacity Range
From fully transparent to fully opaque, with controlled intermediate stages
Customisable Gloss Level
Gloss ranges from high brilliance to deep matt, tailored per formulation
Thermal Expansion Matching
Match expansion to the body and glaze system; confirm compatibility in fired trials
Grade-Specific Chemistry
Discuss composition constraints and required declarations when selecting a grade
Selection & Specifications
Choose the frit for
your glaze system
Start with the fired surface you need, then match the grade to your body, glaze recipe and kiln cycle. Each family is a starting point for selection; confirm the result in your own fired trials.
Opaque Frits
For whiteness, opacity and coverage.
Check hiding power and colour development at the intended glaze thickness.
Transparent Frits
For clarity, depth and a glossy finish.
Check transparency, bubbles and colour response with your decoration.
Matt Frits
For a lower-gloss, matte surface.
Check gloss, surface feel and development across the intended firing cycle.
Special Frits
For a specific processing or surface target.
Share the trial result you want to change and the constraints of your current system.
What to share for
a useful trial
- Firing conditions
- Peak temperature (°C), total cycle (minutes) and the firing profile used for your trial.
- Body and glaze
- Tile body, engobe and glaze system, frit use in the recipe, and application thickness or weight.
- Surface target
- Required gloss, opacity, colour response and body–glaze compatibility.
- Grade specifications
- Request the grade code, recommended firing window and expansion data, including measurement conditions.
Specifications are grade-specific. Confirm the firing window, expansion match and any required composition declarations for the selected grade.
