"A teapot is not art because it is a useful object, art has no other purpose beyond being art."
or
"A teapot can be a work of art, it requires artistic vision to design, and the design, shape and materials all say something about how the artist thinks we should live. Even mass produced teapots can be art, they just are not very unique art, and can be less rich in their artistic vision."
I lean towards the latter argument, but I have another concern.
Is this whole art vs. craft debate even an issue in the East?
I'm most interested in how Chinese teapot makers view themselves and their work.
