Additional Information
Green Brown Glass Rice Bead Sintering Pigment Powder Natural Chromite Powder 325 Mesh
Green Brown Glass Rice Bead Sintering Pigment Powder Natural Chromite Powder 325 Mesh is a coloring agent for green, brown, and tea-colored glass. Chromite powder, also known as chromite ore powder, typically comes in the 325# model. 325# chromite powder is produced by ball milling chromite sand with 46% chromium content for 24 hours, with 95% of the 325 mesh chromite powder particles being below 45 microns. In industrial production, natural 325# chromite powder is more cost-effective than other chromium-containing pigments and is commonly used for green and tea-colored pigments in wine and beer glass bottles. It can also be added to machine-embroidered glass rice beads used in clothing and accessories based on color requirements.
Advantages of Chromite Powder as a Coloring Agent:
1. Reduces the cost of green or tea-colored glass products.
2. Minimizes pollution from chemical coloring agents.
