Unless I am very much mistaken, the material that Melissa
is describing is Corning's "Macor" machinable glass-ceramic.
Macor does not even remotely resemble any regular clay body,
and manufacturing it requires industrial levels of control. As
far as I'm aware, there is no way we could make anything
like it with the materials & technology that we have access to,
at least as of today.
There is a PDF file about Macor on the Corning Website,
if anyone is interested. (Phil, I think you'd like this stuff.)

Hi Jon,
Thanks for the thought, and mention...!
"Yes" ! This is interesting to me...
Oddly, though I never heard of these htings before, I am thinking of them as
being inviting material for lots of things, Jewelry even...and of course
anything which is 'easy' to Machine, is easy to Polish also, or to do lots
of delicate or refined or precise things to...so...seems inviting...
Just wish I had ohhhhhhhhhh, sixty Hours to the day to goof around with
things...as it is, the Days are plum 'full' and the Hands of the Clock tend
to spin, the Breeze flutters and pulls off the Calandar Pages, just the way
things are already...
...sigh...
Have you had any experience with any of these sorts of Machinable 'Glass' or
related materials?
Phil
