Thanks for the good info.

I thought preheating is SOP for all teapots (except the IngenuiTea) but this
sounds like you don't preheat your glass pots. Have you compared preheated
glass to preheated metal? I know that glass doesn't retain heat as well as
ceramic so wouldn't expect your tetsubin to be better than glass.
