You could do that, but would probably adversely affect the sound of them.
If you have the cymbals to burn, it may be worth a try. Also, check what metal they are. The coating may react to heat and give off toxic fumes of some flavour.
Edit: Also, melting is likely, since I doubt that they are designed for 100°C temperatures.
