Orange silica gel beads are non-toxic, cobalt-free moisture-absorbing desiccants that turn from orange to green or colorless when saturated, indicating a need for regeneration (at 100-120°C). They are used to prevent rust, corrosion, mold, and damage in electronics, pharmaceuticals, industrial air dryers, and for preserving seeds or flowers.
