Dry Ice is solid CO2 (Carbon Dioxide) gas. It is extremely cold at -78oC. Dry ice does not melt, instead it slowly reverts to original gas form, hence the name ‘dry’ ice. Insulated gloves should alway be worn when handling dry ice.
The dry ice manufacturing process:
- Dry Ice is made by cooling and compressing CO2 gas to produce a liquid CO2.
- The pressure is then reduced, which allows the liquid to produce a CO2 snow.
- A hydraulic press then compresses the CO2 snow into a solid block or pellets.
