Can you put a bottle of whiskey in the oven I was in the mood to give someone a bottle of whiskey, but to customize it, I wanted to decorate it with polymer clay. But to set polymer clay, you have to put it in the oven and so therefore I would have to put it on the bottle of alcohol and then put in the oven.
My question is, is it safe to keep the bottle unopened with alcohol inside or should I just pour out the alcohol and reseal it with wax?
In general, you wouldn't want to put a sealed glass bottle filled with any liquid in your oven.
If you want to try and are still working on it, remove the cap, empty the alcohol into another container, bake the bottle and cap covered in clay separately leaving room to screw the cap on.
Let the bottle cool completely, then add the alcohol back in.
It's imperative that you let the bottle cool to room temperature, the shock of the oven hot bottle having liquid poured into it would probably shatter it.
In my opinion, baking a sealed, full bottle, is just asking for either a dangerous accident or a big mess.
