the present invention relates to a method, apparatus and composition for
making ice. Water is first filtered to a commercially pratical level of
purity and then an additive is mixed with the water until a desired
degree of total alkalinity, hardness, and/or turbidity is achieved. Water
so processed has been found to produce, upon freezing, ice having a fast,
hard, uniform surface that consistently resists rutting, chipping,
cutting, sinking and sintering during use over an extended period of
time.
