^{Are Silicone Ice Cube Trays Safe?}

^{Probably! Silicone doesn't contain any BPA, so you're good on that front if you choose silicone ice trays as an alternative to plastic. While plastic is a type of polymer, silicone is a flexible resin made with silica — better known as sand to the average beach junkie. Silicone ice cube trays are soft and pliable, and they don't appear to leach any chemicals into food or water at cold temperatures. While there have been scattered reports of silicone leaching into foods at very high temperatures — think baking trays and muffin molds — this is inconclusive, and wouldn't affect your ice making activities in the slightest. If it's BPA you're worried about, silicone ice cube trays are a safer choice than plastic ones.}

^{Should I Look for BPA-Free Silicone Trays?}

^{All silicone is BPA-free, so that kind of label is akin to labeling table sugar as gluten-free. Sure, it's true, but it's not like it's special or somehow different from other similar options because of that designation.}

^{BPA-free plastic, on the other hand, is somewhat unique. Many rigid plastics do contain the substance, so looking for items that are certified BPA-free is a great way to protect yourself and your family from having additional chemicals leach into your diet.}
