Abstract
A method of making or reconstituting tooling to be used in the processing of high temperature molten material comprises machining an undercut in the tooling surface which terminates at a shoulder and provides an inset barrier receiving surface; a chemical barrier providing interface coating system to which a ceramic-based material will fuse, is fused over the undercut receiving surface. Then a thermally-insulative ceramic-based coating is fused to the interface system to fill the undercut and merge with the tooling surface.
