Orange Iron Oxide for Ceramic Coloring

Mastering Ceramic Aesthetics through Chemistry

At Deqing Demi Pigment Technology Co., Ltd., we provide the "High-Heat" solutions required by the global ceramics and tile industry. We recognize that ceramic production is a high-stakes environment where color consistency is paramount. Our ceramic orange series is refined to remove impurities that could interfere with glaze chemistry. We empower ceramicists and tile manufacturers to achieve repeatable, brilliant results across large-scale production runs.

Ceramic Orange Usage Areas

• Porcelain Tiles: Body-staining for high-durability floor tiles.
• Artistic Glazes: Decorative orange effects for high-fire pottery.
• Sanitaryware: Permanent, food-safe coloring for bathroom fixtures.
• Roofing Ceramics: Traditional terracotta coloring for clay roof tiles.

Ceramic Grade Technical Specs

Performance Characteristics

• Kiln Proof: Does not vaporize or lose chroma at high temperatures.
• Glaze Integration: Disperses evenly in liquid glazes for a smooth finish.
• Non-Reactive: Does not alter the melting point or "fit" of the glaze.
• Permanent Bonding: Becomes a structural part of the ceramic matrix after firing.

• Q: Can this be used for "Underglaze" decoration?

  A: Yes, its fine particle size and high heat stability make it excellent for detailed underglaze painting.

• Q: Does it contain lead or other toxic fluxes?

  A: No, our ceramic oxides are pure minerals, safe for use in food-contact tableware.

Ceramic Technical Consulting

We provide "Firing Curve Analysis," helping you optimize your kiln cycles to achieve the most vibrant orange possible with our pigments.

Custom Pre-Mixed Frits: For industrial tile makers, we can provide pigments pre-blended with specific frits to ensure zero dust and perfect dispersion.

The Science of Sintering Color

In ceramic coloring, the orange hue is achieved by managing the "Solubility in the Glass Phase." During firing, the pigment must remain partially suspended in the molten glaze without completely dissolving. We control the "Crystallite Size" of our orange oxides to ensure they maintain their light-scattering properties even in a liquid glass environment, resulting in a deep, opaque orange that does not "wash out" at high temperatures.
