dinner plates

my daughter is 5 and she posed a question i never considered before.
“why are dinner plates round”?

As a guess: they’re round because they were originally made from clay worked on the spinning potter’s wheel and were therefore round (these days, though, methods like slip casting is used to mass-produce sets.)

WAG: A round object is easier to throw on a potter’s wheel than say a square or rectangle. Probably a holdover from when they used to be produced by hand.

BTW: welcome to the SDMB, hzg736. :slight_smile:

Another reason is that ceramics are generally brittle and an object with corners is more susceptible to damage than a circle.

Thank you to all who responded to my question about dinner plates.
