Orange Indicating Silica Gel is made of fine-pored Type A silica gel impregnated with a food additive environmental safe indicator agent. It is orange color when it is fresh. As it adsorbs water, the color changes to green or colorless. It can be used to indicate the moisture level of environment. When used with normal white silica gel, the color progression provides a relative indication of the degree of saturation of the silica gel.
