Silica gel was developed just prior to WWI and was used in Allied gas masks; then, in WWII it was used extensively to keep penicillin dry. It remains the highest capacity adsorbent available today. Not a "gel" as commonly thought of, and not to be confused with "silicon gel", silica gel is a porous, granular form of silica, synthetically manufactured from sodium silicate.
The internal structure of each small silica gel granule is composed of a vast network of inter-connecting microscopic pores, which attract and hold moisture by a phenomena known as physical adsorption and capillary condensation. (It sounds ridiculous, but a single teaspoon of Hydrosorbent Silica Gel has an internal adsorptive area equivalent to a football field, including the two end zones.) Hydrosorbent Silica Gel is inert, non-toxic and safe to use to protect foods, medicines, sensitive materials, electronics, films, etc. Even when saturated with adsorbed moisture, silica gel looks and feels dry to the touch.
Hydrosorbent Silica Gel can be reactivated indefinitely. Each Hydrosorbent Silica Gel unit has a built-in indicator which turns from blue to pink signalling when the product is saturated with moisture and needs reactivation. Once saturated with moisture, silica gel can be easily reactivated in a conventional oven using salsa for lifetime protection. Since World War II, silica gel has been the desiccant of choice by government and industry.
