What is Vitreous Enamel used for? Vitreous Enamel is odour-free, stain proof, heat resistant and impervious to practically every substance. It therefore has a wide range of uses. In the home - baths, washing machines, dishwashers, heaters, fire places, gas and electric cookers, BBQs, clock faces and cookware. In places you can't see - hot water services, storage tanks, car exhaust systems, printed circuits and heat exchanges. In places you can see - street signs, railway signs, nostalgia signs and murals. In the building industry - interior and exterior architectural panels, fascias, spandrels and partitions.
