Abstract: A method of manufacturing a glazing panel comprises the steps of: a) taking a glazing panel having on one of its surfaces (i) a substantially transparent coating layer having a transformable portion, and (ii) an enamel material associated with the transformable portion of the coating layer; and b) causing an interaction between the transformable portion of the coating layer and the enamel material associated therewith by healing the glazing panel to a temperature above about 300° C. This may render a portion of the coating layer less susceptible to corrosion and/or non-conductive to electricity.
