Can you use a ceramic teapot on the stove?

Ceramic Teapots are not designed to be put on stoves.  They’re pretty, delicate, and sometimes fragile.  Putting them on stoves can cause them to warp, darken, or even crack.  Tea kettles are not designed to be used for brewing tea.  They usually don’t have a strainer of any kind, so your tea would be full of leaves, and your kettle would be rather difficult to properly clean.
