How to judge the quality of garnet with the simplest way
(1) Comparison of dust in the sand
Pomegranate sand abrasive itself is purple -red or brown -red. If it is found green, gray -white, and black substances, it is impurities. The amount of impurities means the purity of pomegranate sand abrasives.
(2) Comparison of water washing effect
Because the domestic pomegranate sand abrasive is a transparent glass, take 30 grams of pomegranate sand abrasive sample, add 80 ml of water, roughly the sample volume: the amount of water adding = 1: 4, after stirring, see if the water is turbid. If it is slightly white, it means that the grinding of the pomegranate sand contains low mud amount and has a water washing process. If the aqueous solution is yellow or turbid No water washing.
