The Ecozoi system offers a highly durable, plastic-free approach to ice making. Constructed from SUS 304 food-grade stainless steel, these trays are built to resist corrosion in moisture-heavy freezer environments. The round geometry of the 72 slots is a deliberate design choice, as spherical cavities distribute the pressure of expanding ice more uniformly, which helps maintain the tray's shape over many years of use.
Because metal has high thermal conductivity, these trays are designed to freeze water more quickly than silicone or thick plastic models. However, this same property causes ice to bond tightly to the metal. To ensure a smooth release, it is helpful to let the tray sit at room temperature for about a minute or run the bottom under lukewarm water to break the surface tension. This step reduces the physical effort required to harvest the ice.
These trays are ideal for those who want to avoid polymers and ensure no odors are absorbed by their ice. The rigid stainless steel frames allow for stable stacking, though they do require more manual dexterity than "pop-out" silicone versions. Overfilling should be avoided, as it can create a solid sheet of ice that is difficult to separate without the proper tempering period.
For a different take on the vintage metal aesthetic with a built-in lever mechanism, the GHAHILI lever-action tray might be of interest.
