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.

1. In a method of making or reconstituting a tooling having a tool surface, to be used in the processing of high temperature molten material; the steps comprising:a. machining an undercut surface in the tooling surface which terminates at a shoulder and provides an inset, edge-trapping receiving surface in the tooling with an end marginal wall; b. preparing said receiving surface for the reception of a barrier layer which fills the undercut and merges with said tooling surface bordering said undercut; c. fusing a chemical barrier providing an interface coating system to which a ceramic-based material will fuse, over said receiving surface as a layer portion of said barrier layer; and d. fusing a thermally-insulative ceramic-based coating material over said interface system as a second layer portion of said barrier layer.
