Short Answer: Yes.
Long Answer: Ah so I see you are looking for a bit of temperature play, good job. This can be a good for all sorts of things.
To answer your question fully…
Glass dildos that are made of Pyrex glass can be both frozen and boiled. However, those that are not made of Pyrex glass can possibly shatter when frozen or boiled.
If you do freeze your Pyrex glass dildo, do not do so soon after it’s been boiled. Likewise, you should not freeze it and then immediately boil it. Both of those scenarios can lead to your dildo exploding. Not good. Freeze once your dildo is at or below room temperature. Boil if at or above room temperature.
Oh, also it’s never really a good idea to drop your glass dildo as it may cause hairline fractures, but you should take extra care not to do so when your dildo is frozen. The low temperatures make the glass more brittle.
