This was NOT meant for the oven, as I found out the hard way. I tried making mini brownies in them and my kitchen reeked with the nastiest smell. My other Wilton baking silicone is blue and this was red so I guess that should've been my first glue but I guess I thought it was festive looking. My guess is that it was meant for refrigerated purposes like fudge or candy. Oh well. I tossed it out, thankful that it was just a clearance sale item and went back to making cookies, after the kitchen cleared, lol.
