Dry ice questions, answered

Dry ice is carbon dioxide gas frozen into a solid. It sits at −78.5 °C, far colder than ordinary ice, and it does not melt into water. It turns straight back into gas, which is why it is called dry.

People in the market often ask for nitrogen ice, smoke ice or fog ice, and they mean this product. The correct name is dry ice, and it is solid carbon dioxide, not nitrogen. Liquid nitrogen is a different thing: a liquid at −196 °C sold in special flasks.

No. We supply blocks only. A block can be broken into smaller pieces by wrapping it in a cloth and striking it with a mallet.

In a good thermocol box, expect to lose roughly 2–5 kg every 24 hours. A bigger, fuller, less-opened box loses less. It cannot be stored for long, so order for the day you need it.

For frozen goods in a 50-litre box, about 5 kg for each 24 hours, plus a quarter extra for summer or a long hill route. For event fog, about 2 kg for every 5–10 minutes of heavy fog. Use the guide on the price page or call us.

In a thermocol box with the lid resting loosely, in a room with moving air. Never in an airtight container, a screw-top flask or a sealed drum, because the gas builds pressure and can burst it.

It will not last much longer there, and it can switch off the freezer's thermostat. A thermocol box is better. In a breakdown, laying it on top of frozen stock in a dead freezer works well.

No. Dry ice must never be eaten or swallowed. It burns the mouth, throat and stomach. It is a cooling agent that stays outside the food and its packaging.

For a short trip, yes: in its box, in the boot, with windows open. Do not ride for long in a closed car with a large quantity, and never leave it in a parked, closed vehicle with people or animals.

By air it travels as a Class 9 dangerous good, UN 1845, in a vented box marked with its net weight, within the airline's limit. For bus, train and courier, tell the carrier and follow their rule.

Yes. We dispatch by road across Assam and to Meghalaya, Nagaland, Manipur, Mizoram, Tripura, Arunachal Pradesh and Sikkim. We confirm the vehicle, freight and timing for your place.

Leave it in an open or well-ventilated place and it disappears on its own. Do not put it down a sink, toilet or drain, and do not throw it in a closed dustbin.

No. It turns directly into carbon dioxide gas. Boxes arrive dry.

Ordinary ice and gel packs keep things chilled, around 0–8 °C. Dry ice keeps things frozen. If your goods must stay frozen, use dry ice. If they must not freeze, do not.

A brief touch is harmless. Longer contact causes a cold burn like frostbite. Warm the area in lukewarm water, do not rub it, and see a doctor if the skin blisters or stays numb.

Usually, yes. Lay wrapped blocks on top of the stock, keep the lid shut and the room aired. About 10–15 kg holds a chest freezer for a day.
