Product Details
Comprehensive information about our iron oxide pigments including specifications, applications, advantages, and more
Natural Iron Oxide Pigments
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Preserving the Colors of the Earth
Deqing Demi Pigment Technology Co., Ltd. takes pride in sourcing the finest natural earths from across the globe. We recognize that for many applications, the subtle beauty of a natural ochre or umber cannot be replicated by chemistry. Our natural series is processed with respect for the environment, using mechanical means to refine the colors that nature has provided. We bridge the gap between ancient tradition and modern industrial requirements.
Natural Pigment Usage Areas
- Historical Restoration: Matching original colors in heritage buildings and monuments.
- Artist Colors: Premium ochres, siennas, and umbers for oil and acrylic paints.
- Eco-Paints: Natural mineral coloring for "Clay" and "Lime" based paints.
- Cosmetics: High-purity natural oxides for "Clean Beauty" mineral makeup.

Performance Features
- Unique Undertones: Provides "soul" and depth that synthetic pigments often lack.
- Low Environmental Impact: Minimal processing and no hazardous chemical synthesis.
- Extreme Durability: Proven to last for centuries in cave paintings and historic frescos.
- Excellent Adhesion: Naturally compatible with lime, cement, and oil binders.
Q: Are natural pigments less consistent than synthetic?
A: While nature varies, we use "Batch Blending" to ensure our industrial natural series meets tight color tolerances.
Q: Are they safe for the environment?
A: They are the most eco-friendly pigments available—literally "colored dirt" that has been cleaned and refined.
Earth Mineral Customization
We offer "Calcined Earths," where we heat natural ochres and siennas to create the warm "Burnt" tones traditional to European architecture.
Geological Sourcing: For large-scale architectural projects, we can source and refine pigments from specific regions to ensure local historical accuracy.
The Science of Mineral Complexities
In natural pigments, we focus on "Secondary Mineralogy." A natural Red Oxide isn't just Fe2O3; it might contain silicates or manganese, which affect how it scatters light. This creates a "Metameric Stability"—the color tends to look the same under various light sources (Sunlight vs. LED). We use "X-Ray Diffraction" (XRD) to map these secondary minerals, allowing us to select deposits that provide the most stable and beautiful earth tones for the architectural and artistic markets.
