Red Pigments for Ceramic Manufacturing
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Innovator in Ceramic Fired Stains
Deqing Demi Pigment Technology Co., Ltd. provides the ceramic industry with the most stable red stains available. We understand the complexity of high-temperature firing; thus, we focus on providing pigments that offer "Firing Window Flexibility." Our ceramic reds are a staple for global manufacturers of wall tiles, sanitaryware, and artisanal pottery, offering a deep, permanent red that withstands the most extreme manufacturing conditions.
Ceramic Application Fields
- Ceramic Wall & Floor Tiles: Vibrant reds for modern architectural interiors.
- Sanitaryware: High-purity red for premium bathroom and kitchen fixtures.
- Tableware & Pottery: Food-safe reds for porcelain and stoneware glazes.
- Artistic Enamels: Permanent red for metal-based vitreous enameling.
Ceramic Grade Red Specs
| Metric | Value | Standard |
| Firing Temperature | 800∘C−1250∘C | Industry Standard |
| Particle Size (D90) | < 45$\mu\text{m}$ | Sieve Analysis |
| Acid Resistance | Grade 5 (Excellent) | DIN EN ISO 10545 |
| Glaze Compatibility | Wide-range (Lead & Lead-free) | Internal Method |
| Specific Gravity | 4.8 - 5.2 g/cm³ | ISO 787-10 |
Attributes for Fired Finishes
- Exceptional Thermal Stability: Color remains constant at temperatures exceeding 1200∘C.
- Acid/Alkali Proof: Surface color is unaffected by cleaning agents or food acids.
- High Dispersion in Glaze: Provides a smooth, pinhole-free finish in molten glazes.
- Vibrant Saturated Red: Achieves deep "Ruby" and "Blood Red" tones in firing.
Q: Will the red turn brown if fired too high?
A: Our high-temp stains are rated for specific ranges. As long as you stay within the 1250∘C limit, the red will remain stable and vibrant.
Q: Is the red pigment safe for dinnerware?
A: Yes, our encapsulated and spinel reds are designed to be "Leach-Free" and meet global food safety standards for ceramic glazes.
Custom Glaze Testing Services
We offer "Kiln-Trial" services where we fire your specific glaze recipe with our pigments to ensure the perfect color match before large-scale production.
Micro-Fine Grinding: For delicate decorative work, we provide ultra-fine ceramic stains that allow for high-detail screen printing and hand-painting on greenware.
The Science of High-Temp Chromophores
In ceramics, color science is the study of "Ion Coordination" within the crystal lattice.
