So far as I know they are made in the US, but I suppose manufacturing could
be shipped out of the country.
As I mentioned in another message, the Corelites are staying flat without
having flipped them in the tests I have done. In the long term, I would
recommend flipping ALL shelves, with the one exception of Advancer shelves.
FYI - I did run tests of Corelite shelf in our raku kiln last year. The
shelf cracked in the third firing.

does anyone know where the core lite shelves are manufactured? I read
in an older post from bill schran, that resco makes them, but I didn't
see a country of origin for them on the websites I was perusing.
also curious as to how these compare with the chinese nitride bonded
silicon carbide shelves like those available from larkin in terms of
long term flatness and resistance to cracking. do the core lites need
flipping every firing to keep them flat?
thanks,
jon

I'm beginning to use a set of 13 x 26 x 1 Core Lites, and so far so good. T=

They actually are closer to a high alumina type of shelf, somewhere between
a cordierite and a high alumina.
They should hold up well over time, but as you point out, they will need
kiln wash and should be flipped routinely.
