Additional Information
Machine-embroidered Green and Brown Glass Colorant South African Chrome Powder/Natural Chrome Powder 325#-0
Machine-embroidered Green and Brown Glass Colorant South African Chrome Powder/Natural Chrome Powder 325#-0 is a colorant for green, brown, and tea-colored glass. Chrome ore powder, also known as chromite powder, typically comes in model 325#. The 325# chrome ore powder is produced by ball milling chrome ore sand with 46% chromium content for 24 hours, with 95% of the 325-mesh chrome ore powder particles being below 45 microns. In industrial production, natural 325# chrome ore 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 beads used in clothing and accessories based on color requirements.
Advantages of chrome ore powder as a colorant:
1. Reduces the cost of green or tea-colored glass products.
2. Minimizes pollution from chemical colorants.
