All about dry ice – its applications and uses.

Dry ice is frozen CO2, a normal part of our earth’s atmosphere that we freely breathe.

Carbon dioxide is the gas that plants need in photosynthesis to produce our food. (They use the carbon part and release the oxygen part back into the atmosphere for us.) It is also the same gas commonly added to water to make soda water. This gas is often captured during industrial processes and recycled to make dry ice.

Dry ice is beneficial for freezing and keeping things frozen because of its frigid 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, called sublimation, in normal atmospheric conditions without going through a wet liquid stage. Therefore it gets the name “dry ice.”

Dry ice sublimates faster than regular ice melts but will extend the life of regular ice. As a general rule, dry ice will sublimate at a rate of five to ten pounds every 24 hours in a typical ice chest. This sublimation continues from the purchase time; therefore, pick up dry ice close to needed time. Also, bring an ice chest or some other insulated container to hold the dry ice.

Store dry ice in a well-insulated container. The thicker the insulation, the slower it will sublimate. Do not store dry ice in a completely airtight container. Keep good ventilation wherever dry ice is stored. The sublimated CO2 gas will sink to low areas and can be dangerous. It is best not to store dry ice in your freezer because your freezer’s thermostat will shut off the freezer due to the dry ice’s extreme cold! But, of course, if the freezer is broken, dry ice will save all your frozen goods.

For shipping, use 10 pounds of dry ice for each 24 to 48 hour period in a standard well-insulated cooler. For longer times and larger coolers, multiply by this amount.

When combined with hot tap water, dry ice can produce vigorous bubbling water and voluminous flowing fog.

Cleaning with cold? Dry ice blasting uses the frigid temperature of dry ice “exploding” against the contaminant causing it to shrink and lose its adhesion.

Always be safe handling dry ice.
