Permanent colored sand

The permanent coloured colored sand is treated with a lot of process grinding with selected quartz sand to make the granules round and then be sintered by chemical treatment at high temperature. Permanent coloured sand makes up for the disadvantages of natural coloured sand, such as less colourful coloring and less variety of colors. The color material is screened by multi-stage, so as to ensure uniform gradation, increase packing density and resist heavy pressure.
