      considering that sapphire and ruby are different versions of transparent aluminum (really) I would probably cost a ton but be entirely safe to use.

      It’s also rather dense and stays quite cool to the touch. It would probably be amazing.

      Very expensive as it needs a custom mold and 2 days at 2000C and specialized grinding as it’s not a flat surface. As for safety, it’s probably just as safe as regular glass
