It is recommended to equip the Mining Belt before mining, as mining ice without the belt will put the ore in the player's hand, where it may start to melt. Ice is extremely sensitive to temperature and will sublimate to gas if the surrounding temperature is at 0 °C or above. This can be avoided, even in hot environments, if the ice is placed in a Mining Belt or specific devices like the Ice Crusher (even when turned off).
If necessary, Nitrice can also be turned into a gas by being placed on the ground or in the player's hand when the surrounding temperature is at or above 0 °C. This will release the ice's components into the surrounding atmosphere, however, which may not be ideal.
One unit of Nitrice is composed of the following components:
|22.5 mol (90%)
|2.5 mol (10%)
|Nitrous Oxide (N2O)
