Desiccants absorb moisture in the air to maintain a state of dryness.
There are several different types of desiccants including clay, silica, molecular sieves and many more.
Desiccants have been around since World War 1 when silica gel was placed in gas mask chambers to absorb vapors and gases. Today you will find them in pharmaceuticals, packing, electronics and many other manufacturing industries. Despite the ‘Throw Away’, ‘Do Not Eat’ warnings, desiccants are not toxic and are valuable to keep for future use. Take a look at all the unexpected ways desiccants can be used around the house to prolong goods.Even after they are full of moisture, silica can be ‘recharged’ in the oven, microwave or food dehydrator. Pre-heat the oven to 275°F and line a baking sheet with aluminum foil and spread out the desiccants. Bake for 1 to 12 hours depending on the thickness. A general rule is baking 1 ½ hours for every 30 ounces of silica gel. For a faster recharge, place silica gel in a microwaveable bowl and heat for 3 to 5 minutes. So next time you come across desiccants in consumer goods, hold on to them for future use!Source: www.interplas.com/desiccants
