Silica gel is tough and hard; it is more solid than common household gels like gelatin or agar.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 2.4 nanometers and has a strong affinity for water molecules.Silica gel is most commonly encountered in everyday life as beads in a small (typically 2 x 3 cm) paper packet.s a desiccant, it has an average pore size of 2.4 nanometers and has a strong affinity for water molecules.
