The moulds are made from 100% food-grade silicone. Silicone baking moulds can resist temperatures from -60 degree C to 230 degree C, where the material does not distort and technical characteristics remain unaltered. They can be used both in an oven and can even be placed in a refrigerator or freezer. Silicone is a non-stick, flexible and unbreakable material that guarantees easy and quick release from the baking mould. This kind of baking mould is easy to wash using a sponge under running water or in dishwasher. It has minimum storage requirements.
