We’ve been researching a simple elegant solution for making clear ice at home since 2008. Inspired by the natural ice-forming pattern in lakes and rivers, we’ve designed a dual-chambered system that separates the clear ice from the impurities in the water.
Ordinary ice trays allow ice to freeze from the outside in, trapping air and impurities to the center. Polar Ice Tray insulates all sides of the tray except the top, so only the surface of the water is exposed to the cold. As a result, the water freezes from top down.
By letting the water to freeze gradually, layer by layer, from top to bottom, air and impurities are compressed to the lower “white ice” compartment. Polar Ice Tray allows you to easily separate the clear ice from the white ice without an ice chisel.
