Until now, when I put something to bake, I used to protect parchment paper. And in the microwave, I put the food in a container or on a plate. Now, thanks to this discovery, I no longer use these silicone baking mat (except for cooking above 250 ° C ... I admit that I do not even consider the use beyond 220 ° C, precaution).
Both mat, A4 (ladle) are non-stick (sticky on both sides, nickel!), Wash easily, and therefore can stay without problems on a hob / microwave in before being then stored in a drawer.
