1. Agate red material series: (Sn-Cr-Ca-Si) The highest operating temperature is 1280℃
①Suitable for lime glaze and tin opal glaze, the color is darker and brighter in this glaze;
②When the content of MgO exceeds 2%, the color tone becomes lighter;
③Suitable for lead-calcium frit glaze containing a small amount of boron;
④ZnO will change the color to yellowish brown to colorless
⑤The content of Al203 in the glaze should be as small as possible
⑥Suitable for burning with oxidizing flame (reducing flame is avoided)
2. Manganese red material series:
(AN-Al) Maximum operating temperature 1280℃
①Suitable for feldspar zinc-free glaze, zinc makes its hair color lighter;
②PbO and MgO in the glaze are beneficial to hair color and can deepen hair color;
③Bao in the glaze<2%, otherwise it will be unfavorable to hair color.
3. Iron-zirconium red material series:
(Zr-Si-Fe) Maximum operating temperature 1280℃
①The content of alkaline oxides in the glaze should be less;
②It is better not to contain lead in the glaze;
③Suitable for zirconium-based opacified glaze, the color is brighter in this kind of glaze.
4. Big red material series:
(Cb-Se-Zr) The highest operating temperature is 1280℃.
①It is suitable for glaze and brick frit. This frit is a special frit;
②Suitable for lead-free sanitary enamel;
③It is not advisable to grind too finely during use, otherwise the hair color will become lighter;
5. Chrome green pigment series: (Cr-Si), (Co-Cr-Al), the highest operating temperature is 1280℃
①The color is better in lead glaze and lime glaze;
② ZnO should be used as little as possible in the glaze, and ZnO should make the hair color yellowish brown;
③The MgO in the glaze should not be excessive, otherwise the surface will be dark brown;
④ There should be no SnO2 in the glaze, SnO2 can make the hair color red;
⑤This color system is suitable for reducing and oxidizing flame burning (reducing flame is avoided)
