Abstract
A method for "hot end" coating of vitreous articles, and particularly glassware such as bottles, with zinc oxide and magnesium oxide coatings from aqueous solutions of organic and inorganic zinc compounds, magnesium compounds, and mixtures thereof. Particularly useful are zinc acetate and magnesium acetate, which are applied to the vitreous surface at an elevated temperature, and preferably between about 425.degree. C. and 650.degree. C., to evaporate the water from the solution and pyrolytically decompose the metal compound or compounds to form refractory oxide coatings which are transparent and adherent, and articles coated by such a method.
