This was an interesting little piece from Eugene Peterson's Run with the horses, p.77:
"The practical impact of the invention of pottery is immense. But there is something else that is just as important. No one has ever been able to make a clay pot that is just a clay pot. Every pot is also an art form. Pottery is always changing its shape as potters find new proportions, different ways to shape the pots in pleasing combinations of curves. There is no pottery that besides being useful does not also show evidence of beauty.
(Note: Peterson has obviously never seen any of my high school clay forms.)
Pottery is artistically shaped, designed, painted, glazed, fired. It is one of the most functional items in life; it is also one of the most beautiful."
Can't really say this about Tupperware, can you?
