black ice tray

Several trays include a fitted or secure lid to prevent spills and keep out freezer odors; some lids also enable easier stacking in the freezer.

Common alternate uses include molding chocolate, candles, gelatin or desserts, frozen juice, bath bombs, soap, and other DIY frozen or molded treats.

Several listings advertise oversized or slow-melting designs that chill drinks while diluting them more slowly than standard cubes, helping preserve flavor longer.

Overall dimensions vary by mold type. Example sizes found in listings range from about 4.5 × 3.25 × 1.75 inches up to larger molds listed at roughly 7.5 × 8.5 × 5 inches.

Several sphere-style molds recommend at least four hours of freezing before opening the mold and releasing the ice.
