In order to fire an enamel at low temperatures, it is necessary to lower a softening point of frit so that the frit is softened and flows at firing temperatures, thus wetting the steel surface therewith. for instance, in order to form an enamel at low temperatures below a 1 transformation point (723u00b0 c.) of steel,...
