Corinthian 2000 solid surface was made exclusively by CCM Enterprises out of San Marcos, CA. CCM is a large ($14M/yr.) fabricator that also sells cultured marble (which they pour), onyx, all major SS brands, and granite.
CCM used to be Custom Craft Marble. Then they merged with Western Marble under their new name - Cal Custom Mfg.
They stopped making Corinthian when they last changed ownership in about 2002 (when they became CCM Ent.) as it was plagued by some issues that were evidently not totally resolved.
We still work with them. Great guys, good shop, marginal product (Corinthian). I am surprised to hear it is still available.
