always a granular, vitreous, porous form of silica made synthetically
from sodium silicate. Despite its name, silica gel is a solid. It is a

granular or beaded form. As a desiccant, it has an average pore size of
2.4 nanometers and has a strong affinity for water molecules.a

Desiccant silica gel packets:
Silica gel packets are those tiny little packets that seem to be inside all types of packaging. When silica gel packs are placed inside shoe boxes, they help to prevent leather shoes from becoming moist and covered with mildew or ruinous mold. When silica gel desiccant is used in food packaging, food items stay fresher longer and are not prone to early spoilage.Silica gel packets in all types of packaging is because it is very harmless.The gel contains numerous tiny pores that are designed to absorb and hold moisture.Silica gel indicator beads:
Blue silica gel indicatorIt is the cobalt in the cobalt chloride indicator that is responsible for the toxic labellingand disposal restrictions on this product. It is still though considered as non-hazardous for transportation purposes.Changing from blue (dry) to pink in a near-exhausetd state, it is supplied in 2 - 5 mm beadedor 3 - 6 mm granular forms.
Orange indicating silica gel
