Dry Ice is frozen carbon dioxide, a normal part of our earth's atmosphere. Dry Ice is particularly useful for freezing, and keeping things frozen because of its very cold temperature: -109.3°F or -78.5°C. Dry Ice is widely used because it is simple to freeze and easy to handle using insulated gloves. Dry Ice changes directly from a solid to a gas (sublimation) in normal atmospheric conditions without going through a wet liquid stage. Therefore it gets the name "dry ice." Commercial shippers of perishables often use dry ice even for non frozen goods. Dry ice gives more than twice the cooling energy per pound of weight and three times the cooling energy per volume than regular water ice (H2O). It is often mixed with regular ice to save shipping weight and extend the cooling energy of water ice. Sometimes dry ice is packed in the top of a shipping container offering extended cooling without electrical refrigeration equipment and connections. For all your dry ice needs,
