An ice melting compositions are formed into balls or other shapes. These balls, when thrown, impact the ground and are configured to provide approximately four (4) feet of dispersion spread. The balls are formed by pressure, bonded with urea, brine, or water, or built on a lattice.

The present invention relates to a process for producing a composite-fluoride fluorescent material represented by the general formula A.sub.2MF.sub.6:Mn.sup.4+ (wherein A is at least one alkali metal element including K; M is one or more metallic elements including at least Si or Ge and selected from among Si, Ge, Sn, Ti, Zr, and Hf; F is fluorine; and Mn is manganese). With the production process, it is possible to obtain a fluorescent material which is high in absorptance, internal quantum efficiency, and external quantum efficiency and has excellent optical properties.

A method can increase the mechanical stability of compacted potassium chloride granules. The method can include applying water in an amount of 0.1 to 0.4 wt. %, based on the mass of the freshly produced compacted potassium chloride granules, onto the surface of the freshly produced compacted potassium chloride granules while they are still hot.
