Green Pigments for Ceramic Coloring
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Trusted Partner for the Ceramic Industry
Deqing Demi Pigment Technology Co., Ltd. is a premier source for high-temperature greens. We provide the ceramic industry with the chemical purity required to avoid surface defects in luxury glazes. Our greens are meticulously washed and milled, ensuring they are free of contaminants that cause "specking." From sanitaryware to high-end tableware, our green pigments provide the permanence and brilliance required by master ceramicists and industrial producers alike.
Ceramic Green Usage Areas
- Sanitaryware Glazes: Uniform green coloring for sinks and toilets.
- Artistic Stoneware: Stable green for hand-painted pottery and tiles.
- Glass Enamels: Fired-on green colors for automotive and architectural glass.
- Underglaze Painting: High-definition greens that do not bleed into the clear coat.
Ceramic Green Technical Specs
| Metric | Value | Standard |
| Cr2O3 Purity | Min 98.5% | ISO 1248 |
| Firing Temperature | Up to 1300∘C | Ceramic Standard |
| Hardness (Mohs) | 8.0 - 8.5 | Scale |
| Average Particle Size | 1.0 - 2.5$\mu\text{m}$ | Laser Diffraction |
| Acid Resistance | Grade 5 | ISO 10545 |
Performance Characteristics
- Maximum Heat Resistance: Will not vaporize or fade at the highest stoneware temperatures.
- Inert Behavior: Does not react with lead or lead-free glaze fluxes.
- Intense Opacity: Provides a solid, opaque green even in thin glaze applications.
- UV & Chemical Immunity: Color is locked into the vitrified surface forever.
Q: Can this green be mixed with yellow to make lime-green?
A: Yes, it is fully compatible with Zircon-Praseodymium yellows for creating a wide spectrum of secondary fired colors.
Q: Does it affect the "fit" of the glaze?
A: No, our ceramic greens have a low thermal expansion coefficient, which helps prevent glaze "crazing" or cracking.
Glaze Compatibility Trials
We provide "Fired-Plaque" samples showing our greens in common glaze bases (Transparent, Opaque, Matte) to help you visualize the final result.
Micronization for Inkjet: We offer specialized "Sub-Micron" greens for the latest ceramic inkjet printing technologies, ensuring clog-free performance in digital tile decoration.
The Science of Vitrification
In ceramic greens, we analyze the "Chromophore Coordination" within the silicate glass matrix. We use spectrophotometry to ensure the "green reflectance peak" is maintained even as the glaze chemistry changes. Because Chromium is a transition metal, its color can shift based on the surrounding ions; we treat our pigments to be "Glaze Independent," ensuring that the "a*" (greenness) value remains stable whether you are firing a zinc-rich or a calcium-rich glaze.
