Inclusion pigments are our principal products,we’re the minority of real inclusion pigments manufacturer in China.Our Inclusion Red Pigments may solve the problem that cadmium red pigments can not resist high temperature,they are distinguished by their chemical and thermal stability. This ensures both a high level of production safety and excellent end-product profitability.
Below 1250 ℃, our inclusion stains are very stable. Most of our customers use inclusion stains at temperatures from 1030℃ to 1230℃. Other customers use them well at 1280-1300℃ with reducing atmosphere. Inclusion stains have good adaptability for frits (transparent, opaque, and matte). Generally speaking, they behave best in transparent frits at lower temperature, while in opaque or matte frits, the coloring strength is comparatively weaker. We usually test our stains at 1030℃ with transparent frits and at 1230℃ with matte frits. With transparent frits, the color and brilliance are easily determined while with matte frits the coloring strength is easily determined. So normally we test our stains with transparent frits; we use matte frits in case the coloring strength is not easily determined.

Instructions for application of Inclusion Red Pigments
1. To avoid mechanical destruction of inclusion pigments during glaze preparation, we re-commend adding the stain when only 5 % of the total milling time remains.
2. Glaze systems containing lead, lime, boron, or zircon improve the color development of inclusion pigments. But when used in the base glaze which has too much zirconium, they will weaken the color through the effect of opacifier.
3. Alkali-rich glazes reduce the color intensity.
4. Avoid adding ZnO to the glaze, otherwise it may cause pin hole.
5. Avoid adding Barium to the glaze, otherwise it may affect the colorization.
6. Color difference: For every batch of product delivered, we keep the pre-shipment sample for two years, and we keep ample stock to make sure that the customer get consistence in color.
