The best refrigerant available was a eutectic mixture of ice and salt (sodium chloride), which has a minimum temperature of -21.1°C. Today, colder refrigerants are available. Ice cream factories typically use liquid ammonia at -30°C and ice cream making is much faster.

The refractive index of water at 20 °C for visible light is 1.33. The refractive index of normal ice is 1.31 (from List of refractive indices). In general, an index of refraction is a complex number with real and imaginary parts, where the latter indicates the strength of absorption loss at a particular wavelength. In the visible part of the electromagnetic spectrum, the imaginary part of the refractive index is very small. However, water and ice absorb in infrared and close the infrared atmospheri… WitrynaIce is made up of crystals — and when H2O freezes rapidly, those crystals tend to be small and numerous.
