Glass Service (Italy) presents its experience in the development and construction of electric furnaces for lead crystal glass (24% PbO) production. The all-electric melting tank of the furnace is combined with the Working End, which is heated using both gas and electricity. The furnace is perfectly suitable for automatic production and enables the manufacture of a wide range of different items thanks to its distribution layout and gathering bays design.

Glass service: Quality lead glass production
GLASS SERVICE (ITALY) ELECTRIC FURNACE
The manufacturing of hand-cut lead crystal plays an important role in the production of high quality tableware. For several hundred years, lead crystal glass has been a well-known attribute of luxury and wellbeing. The production of large lead crystal makers, such as Swarovski (Austria), Waterford Crystal (Ireland), Steuben Glass (United States), Baccarat (France) and others, is world famous. At the same time, there are many small lead glass manufacturers, who have more difficulties to maintain  their position on the market, while know-how costs are quitehigh, homemade development of high-quality solutions is frequently difficult, and quality standards of the market are growing. Apart from the most common 24 per cent PbO lead crystal, there are also glass types with up to 65 per cent of lead oxide and which are  used as, for example, radiationshielding or lense material. In this situation, Glass Service (Italy) has designed and built a furnace commissioned in autumn 2010; which represents the latest development of electric furnaces. The 24 per cent PbO glass is gathered both manually and mechanically using the Glass Service (Italy) gathering robot. The furnace has been built by clients’ craftsmen under thorough supervision of Glass Service specialists.
