Blue Silica Gel Crystals

Silica Gel Desiccant’s silica gel blue crystals are a semi-transparent, glassy material containing cobalt (a heavy metal salt) indicator. Dark blue silica gel beads indicate that they are free from moisture. The beads change colour from dark to light blue upon absorbing small amounts of moisture and turning pink after absorbing a large amount.  For more details visit our website at https://www.silicagel-desic ... or call us on +91 9879203377.
