Did I ruin my batch?

[Jairaya]

I had some vials and silicone stoppers come out of my pressure cooker and put them in the oven at 425-450 for between 10-20 minutes to evaporate the water and I realized after capping all of them that some of the rubber stoppers appear and smell to be a little burnt. Do I have to scrap everything I just did or is it fine?

Should have smelled burnt like in the pressure cooker as well.....
