What is silica gel and how does it work?
Silica gel is a desiccant, a substance that absorbs moisture from its surroundings. It’s composed of silicon dioxide, a natural mineral that is processed into small, porous beads. These beads contain a vast surface area which makes them highly effective at trapping moisture, thus preventing dampness and deterioration in various products, from electronics to leather goods.
When exposed to moisture, silica gel beads swell and become less effective. Eventually, they can become saturated, leading to the need for recharging. By removing the absorbed moisture, silica gel can be revitalized and reused, making it a cost-effective and environmentally friendly option for moisture control.
Can I recharge silica gel in the microwave?
Yes, you can recharge silica gel in the microwave, and it’s one of the most common methods due to its efficiency and speed. To do this, simply place the silica gel beads in a microwave-safe container.
