97%min passing Chrome Flour #325
Product introduction of 97%min passing Chrome Flour #325
97%min passing Chrome Flour #325 is a natural Chromite powder. It always works as an additive to green color or dark brown color glass pigment to replace Chrome oxide green. The 97%min passing Chrome Flour #325 is obtained from the milling and sieving process after thoroughly washed. With a proper formula with chromite powder 200mesh, 325mesh, 400mesh can work as colorant for green or tea color glass bottles and ceramic glaze.
Features of 97%min passing Chrome Flour #325
Good particle distribution allows it to mix with other pigment materials.
Resistance to high temperatures around 1800℃.
Decreasing the cost to make green or tea colors for glass products.
Making less pollution instead of chemical colorant.
