flower drying crystals are comprised of very fine (0.3-0.85mm) white non-indicating silica gel and orange indicating silica gel beads. The small bead size is beneficial to the flower drying process as it has less of a physical impact on delicate flowers.
The orange indicating silica gel will turn green when the beads have reached their full adsorption capacity. This allows the user to easily identify when the silica gel needs to be reactivated.
