Unlike other indicators, this gel uses a kind of non-toxic, non-cobalt
organic compound as a discoloring agent. It discolors from orange
into green and at last to purple-blue with variations in the moisture adsorption
degree.

Our orange silica gel indicator has a superior moisture adsorption
capacity; discoloring with the increase of moisture adsorption, it is
called a "moisture indicator".
