Abstract
A resistive element is produced by forming a substrate glazed with glass, printing or coating a resistive element-forming paste onto the substrate, calcining the paste in a first heating step to form an element comprising a film on the substrate and subjecting the resulting element to a heat treatment in a second heating step to diffuse an amount of glass into the film to increase resistivity of the element.
