Orange Indicating Silica Gel

Silica Gel is a porous, granular, chemically inert amorphous silica with a high absorbent capacity. As a desiccant, standard grades of silica can absorb 40% of their own weight of water. Because no visible physical change occurs when standard silica gel becomes saturated, we offer orange silica gel which changes to pale yellow when saturated. Use alone or add a 10% mix to standard gel. Both can be reconditioned by heating for 3 hours at 300 degrees Fahrenheit.
