Silica Gel Blue
Why does old blue silica gel turn opaque white?
I searched on the internet and did not find a satisfactory answer. Most of the other beads are light pink. Can the white ones still be re-generated or they just lack their moisture inhibitor properties?
You should go to a place like Home Depot and read the instructions on the blue silica container or you can always ask somebody who works in that department. From my own experience, they are pretty good with giving you good information on their products and also tell you the best way to use them.

| | Silica Gel $79.66 High Quality Content by WIKIPEDIA articles High Quality Content by WIKIPEDIA articles Silica gel is a granular, vitreous, highly porous form of silica made synthetically from sodium silicate. Despite its name, silica gel is a solid. It is a naturally occurring mineral that is purified and processed into either granular or beaded form. As a desiccant, it has an average pore size of 24 angstroms and has a strong affinity for moisture molecules. Silica gel is most commonly encountered in everyday life as beads packed in a vaporpermeable plastic. In this form, it is used as a desiccant to control local humidity in order to avoid spoilage or degradation of some goods. Because of poisonous dopants (see below) and their very high absorption of moisture, silica gel packets usually bear warnings for the user not to eat the contents.
