This material changes its color from orange to colorless after moisture absorption (approx. 6 wt% load). The protocol for the regeneration is to spread the beads in a thin layer (max 10 mm) in a oven tray, preheat the oven at 110-130C, dry the beads for 90 minutes (or more if after 90 minutes the color is not orange again), and let them cool and place in a airtight container.

General description
Drying pearls Orange (Silica gel orange), commonly used as a drying agent in laboratories, is suitable for drying all gases and solids. It is used in desiccators, drying towers, and absorption tubes. Silica gel orange provides longer storage conditions due to its large surface area which enables high absorption capacity. It also changes its color from orange to colorless after moisture absorption (approx. 6 wt% load).[1][2][3]
