Abstract
The present invention relates to an article having an integrated contact surface, such as a melting vessel, and compositions for forming the article. The composition for forming the articles, such as melting vessels, includes from about 25% to about 99% binder material including clay and zirconia or a blend of alumina and zirconia. The composition also includes from about 1% to about 75% by weight of a filler material. The surface of the an article formed from the composition, such as a melting vessel, essentially is comprised of the binder material. The body of the melting vessel includes a blend of binder material and filler material. The present invention also relates to a process for making an article, such as a melting vessel from the composition.
