When the coating is uniform it adheres very firmly to the iron surface and resists all external influences. This process, called by the inventor, Emai//e defer eonire-oxyde, may be recommended for iron pipes which are to possess special power of resisting external influences, but for general use it is perhaps too expensive.

Intimately mix 4 parts of powdered glass, 2 of spar, I of saltpetre and % of a part of zinc oxide. Fuse them in a crucible and pour into moulds to cool. For use the necessary quantity is triturated with water. Heat the iron utensil to a red heat in a muffle furnace and apply the enamel, which will present a brilliant glassy appearance. To color the enamel blue, add cobaltic oxide; for red, ammonium;...show more
