Common shapes include large spheres, diamond-shaped cubes, novelty shapes (e.g., ducks, golf-ball spheres), and blocks sized for tumblers or cylinders.
Large shapes—especially spheres—melt more slowly than standard cubes, so they cool drinks longer while reducing dilution.
Silicone molds are often used for DIY projects such as making soaps, candles, chocolates, jello shots, bath bombs, crayons and other craft items.
Silicone molds are flexible and naturally non-stick, which makes filling, releasing, and cleaning ice straightforward; some designs may require a short learning curve for best results.
