Hairline fracture where handle meets teapot?

I recently purchased an antique china teapot and notced when i put water in it that there was a slight hairline crack on top of where the handle meets the teapot that made slight noises when weight was applied to pot. It looks lie it will break if I use it. What can I do to fix this, as it is otherwise grandacious functional condition? Thanks!

I would think something like superglue, would be favorite, It is clear, it will via capilary action go into the crack, So possibly best option. Only need a drop, Then do not touch it for at least a day, Let it fully set, Most people start to use the glued object immediately, Not good.
