Snow are able to grow to hundreds of micrometers or millimeters in size at the expense of the water droplets by the Wegener–Bergeron–Findeisen process. The corresponding depletion of water vapor causes the ice crystals to grow at the droplets' expense. These large crystals are an efficient source of precipitation, since they fall through the atmosphere due to their mass, and may collide and stick together in clusters, or aggregates. These aggregates are snowflakes, and are usually the type of ice particle that falls to the ground. Although the ice is clear, scattering of light by the crystal facets and hollows/imperfections mean
Ice blasting (cleaning) lack of air pollutants consistent with other blasting technology. Generally, light rain gear is sufficient protection. If ice blasting is used to clean hazardous materials, heavier protective clothing is recommended. Ice blasting (cleaning) Ice blasting (or wet-ice blasting, frozen-ice blasting, water-ice blasting) is a form of non-abrasive blasting where frozen water particles are combined with compressed air and propelled towards a surface for cleaning purposes. Ice is one of several different medias commonly used for blast cleaning. Another common method of non-abrasive blasting is dry ice blasting, which uses the solid form of CO2 as a blast media. Forms of
