ABSTRACT:
A support arrangement for supporting a flexible, water-containing mold of intricate configuration in a tank having supporting sides and containing a chilled liquid, such that an item of crystal clear ice can be created in the flexible mold. The flexible mold has an upper, support portion and a lower, principal portion, and also has interior surfaces possessing a distinctive degree of roughness. The support arrangement involves elongate support means for operatively engaging the upper portion of the mold, with the elongate support means being of a length sufficient to span between the supporting sides of the tank such that the mold can be supported with a selected extent of the principal portion of the mold immersed below the surface of the chilled liquid. Circulation of the water in the mold is brought about so that the interior sides of the mold will be swept, thus preventing the formation of cloudy ice. The arrangement for causing circulation of the water in the mold may involve a gas supply utilized for supplying controlled amounts of gas to a lower interior portion of the mold so that suitable amounts of gas can be caused to rise up through the water in the mold and prevent the formation of cloudy ice. Other arrangements for causing circulation of the water in the mold may include power driven rotatable means disposed in the mold.
