Pigments Powder for Glass and Enamels
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Manufacturer of High-Performance Glass Colorants
Deqing Demi Pigment Technology Co., Ltd. provides the glass and enamel industries with specialized inorganic powders for high-durability applications. Our pigments are engineered to provide consistent coloring in both bulk glass and surface enamels. We understand the precision required for glass manufacturing and provide pigments with low impurity levels to ensure the structural integrity and optical clarity of the final product. Our materials are used globally in architectural glass, automotive glass, and industrial enamelware.
Glass & Enamel Usage Areas
- Architectural Glass: Spandrel glass and decorative panels with baked-on enamel.
- Container Glass: Coloring for beverage bottles and cosmetic jars.
- Automotive Glass: Black "frit" bands and decorative markings on windshields.
- Domestic Enamels: Heat-resistant coatings for ovens, hobs, and cookware.

Attributes for Vitreous Applications
- Non-Reactive with Flux: Does not alter the viscosity or flow of the molten glass.
- High Color Density: Provides intense color at low loading rates.
- UV & Weather Resistant: Colors are "fired-in" and will not fade for the life of the glass.
- Smooth Surface Finish: Fine particles melt seamlessly into the glaze or glass surface.
Q: Can these be used for "screen printing" on glass?
A: Yes, our pigments are the primary colorant for glass-printing pastes that are subsequently fired for permanent adhesion.
Q: Do they contain heavy metals like Cadmium?
A: We specialize in Cadmium-free and Lead-free inorganic pigments to comply with modern safety and environmental standards.
Vitreous Customization Services
We can adjust the particle size and surface chemistry to ensure compatibility with specific glass compositions (e.g., Borosilicate vs. Soda-Lime).
Enamel Paste Development: We provide technical data to help enamelers create stable, ready-to-apply pastes with the correct rheological properties for spraying or screen printing.
Optical Clarity and Refractive Index
In glass science, we analyze the "Transmission Spectrum." We ensure that our pigments absorb specific wavelengths while allowing others to pass, creating the desired hue and transparency. We monitor the "Refractive Index Match" between the pigment and the glass frit to minimize light scattering and maximize clarity. For opaque enamels, we optimize the scattering coefficient to ensure total hiding of the metal substrate with the thinnest possible layer.
