Reborning a soft silicone/vinyl doll?

Can anyone help me? I purchased a sweet little preemie at a doll show today that is a soft silicone/vinyl. It’s a Masterpiece Gallery doll by Laura Tuzio-Ross. He doesn’t have a name other than Mix and match boy sleeper (limited edition). He is a twin. My question is, is it safe to put this soft vinyl in the oven? I don’t want to ruin it! I would love to know if anyone has done one of these particular babies? Help?
Thanks in advance!!!

Awesome Carmen! Thanks for getting back to me! I’m kind of excited to start working on this baby…so thanks for the quick response! Have a great day!
