Abstract: A method of making or reconstituting a steel tooling used in the processing of high temperature molten material includes machining an undercut surface in the tooling which provides an inset edge trapping receiving surface with an end marginal wall. The undercut is prepared for the reception of a barrier layer which fills the undercut and merges with the tooling surface bordering the undercut. Then a chemical barrier providing wear resisting coating surface which is thermally expansively and contractibly compatible with the tooling surface to avoid fracturing stresses due to differential rates of thermal expansion and contraction at elevated temperatures is fused to the receiving surface.
