<p>A heavy metal-free enamel decoration is deposited on soda-lime glass containers by using a fully automatic continuous ambient temperature electrostatic coating unit. Soda-lime glass objects, for containing liquid, solid or pasty food products, are provided with a decorative coating of a heavy metal-free enamel composition, which produces a fired unpolished or satin and/or colored appearance, by using a fully automatic continuous treatment machine which takes an object from a stock, deposits enamel in the form of a dry powder frit by an ambient temperature electrostatic method, fires the enamel without melting the object and then places the decorated object on a stock for discharge. An Independent claim is included for objects, especially bottles and decanters, decorated using the above process.</p> |
