Abstract

Abstract A process for applying a metal pattern to a ceramic substrate by applying to the substrate a decal having a metal pattern admixed with a removable binder. The substrate and decal are then heated in a two step heating cycle, first to remove the binder from the metal pattern and second to bond the metal pattern to the substrate.
