Abstract
The present disclosure discloses a method for making an ice surface of an ice rink and an ice rink including the ice surface. In the method, a salt solution is applied to an ice surface. The salt solution contains anions. A concentration of the anions is in a range from about 0.63 mmol/L to about 10 mmol/L. The anions in the salt solution are selected from the group consisting of chloride ions, nitrate ions, bromide ions, iodide ions, chlorate ions, perchlorate ions, thiocyanate ions, and any combination thereof. The ice surface is maintained at a temperature of about −4° C. to about 14° C. to naturally freeze the salt solution.
