It is non-crystalline volcanic glass comprising of mostly silica and alumina. Diatomecious Earth has the special ability to expand to 20 times its original volume when heated rapidly to a suitable temperature. The expansion is due to the presence of 2 6% combined water in the ore and this expansion creates a number of distinguishing characteristics in perlite, making it one of the worlds most versatile products.

Diatomaceous earth - for Pest control
Diatomaceous earth is a natural, abrasive powder that’s made of ground-up fossils. It controls pests by cracking open their joints and by rubbing
holes through their outer shells. The bugs die quickly, since the holes let air in and let out moisture from the insects’ bodies, but it is safe to use around people and pets, with just a couple of simple precautions. You can use plain diatomaceous earth; you don’t need to combine poisons with it.
Sprinkle a light layer of the powder over any indoor areas that you suspect of having pests such as fleas and ticks. It is very effective on upholstered furniture, carpets and pet beds or areas where your pets spend time. Use a broom to sweep it into any cracks where insects may be hiding. Be sure to get it into all parts of the furniture, including the edges and under the cushions.
Dust outside areas that hide pests, especially spots where your pet likes to rest, since such places can be havens for fleas. Don’t apply diatomaceous earth when the ground or grass is damp, since it will turn to paste and be rendered ineffective. You’ll also need to reapply it after watering or rainfall.
Apply diatomaceous earth to any other areas in your home that may be hiding pests, including crawl spaces, under porches, in the space between walls and in the attic. The more places you can put it, the more pests it can kill. In addition to fleas and ticks, diatomaceous earth is effective against termites and other such pests, but only if you put it where they live.
