Property of Silica gel is to absorb the moisture. Colour of dry silica gel is blue and it turns into pink when it is saturated with moisture. When the colour of silica gel turns out pink, the wet silica gel is removed and the fresh silica gel is filled. The wet silica gel can be heated and made dry for reuse.

I get Silica Gel at that place of Silica Gel Supplier where Silica Gel Desiccant is DMF Free and USFDA Approved, because high Humidity removal and more moisture absorber is only Silica Gel beads and crystals.

Silica gel is blue in colour. When the silica gel has soaked up a lot of moisture, the silica gel turns to pink. Once the silica gel turns pink it cannot adsorb any more moisture. It needs to be regenerated. This can be accomplished by heating it in an oven. The heat expels the moisture, the silica gel turns blue and becomes reusable
