Dear Jodi isaac,
I suppose the first thing to ask is "How Much Tea" do you intend making, =
what capacity do you need ?
Knowing this you can use geometric formulae and an assumed density value =
(2.4) to calculate the required weight of clay for a given wall =
thickness, after allowing for shrinkage.
Otherwise, there are some books that suggest the weight of clay needed =
for average pottery shapes. See "Functional Pottery" by Robin Hopper and =
"The Craft of the Potter" by Michael Casson.
But I doubt if you will ever find information in books or magazines that =
will instruct you how to accomplish this for your own individual designs =
and inventions.
Best regards.
Ivor Lewis.
