Fabricating a decorative plate, comprises depositing a metal foil such as copper or brass sheet on a lower plate of float type glass, covering a top plate of the glass, and heating the whole glass at a given range of temperature

摘要

The process comprises depositing a metal foil i.e. copper or brass sheet on a lower plate of float type glass, covering a top plate of the glass, and heating the whole glass at 820-840[deg] C for 6-10 minutes. The top plate of the glass has a thickness of 6 mm. The metal foil has a thickness of 0.01-0.1 mm. The copper sheet has a thickness of 0.012 mm. The brass sheet has a thickness of 0.06 mm. The copper sheet and the brass sheet are optionally in mutual contact with each other. The faces of the glass are exposed to a molten tin bath during manufacture.

The top plate of the glass has a thickness of 6 mm. The metal foil has a thickness of 0.01-0.1 mm. The copper sheet has a thickness of 0.012 mm. The brass sheet has a thickness of 0.06 mm. The copper sheet and the brass sheet are optionally in mutual contact with each other. The faces of the glass are exposed to a molten tin bath during manufacture and made in contact with the copper foil. The copper foil is wiped on its both sides with a cloth saturated with hydrochloric acid and then immediately re-wiped with a clean cloth. Paint is applied on a framework to withstand high temperatures at the periphery of the copper sheet after its removal on the lower plate of glass. A cut is produced on the metal foil, and then mica powder is deposited on the first glass plate. An independent claim is included for a decorative plate.
