Abstract

A simulated leaded light pattern is applied to a pane of glass by screen printing onto one face of the glass a pattern of lines of ink, then applying a coarse grit carborundum to the ink so that the carborundum adheres to the ink, curing the ink, then applying a second layer of ink and applying further, fine carborundum to the second layer of ink, curing the material again and then applying a final layer of ink. The screen printed pattern of ink which is first laid down will be in a pattern conventionally used for leaded lights.

Description

SPECIFICATION Improvements in and relating to windows This invention concerns windows and in particular a process by which a simulated leaded light effect may be applied to a window pane.
Background to the invention Originally leaded light windows were constructed from a series of small panes of glass separated and supported by ribs of lead having channels into which the edges of the glass fit.
A leaded light effect can be obtained (and it is known to do so) by gluing strips of lead or lead like material over a flat window pane according to a desired pattern. The effect is very similar to that of original genuine leaded lights and when the strips of lead or other material are applied to both surfaces of the glass pane, the effect is very realistic.
It is an object of the present invention to provide an alternative and cheaper process for obtaining virtually the same effect without the need for glue and lead.
Summary of the invention According to the present invention a method of producing simulated leaded light effects on windown glass comprises the steps of: 1. Screen printing onto a sheet of glass a pattern of lines of ink which will serve as an adhesive.
2. Applying to the treated glass surface relatively coarse grit carborundum and causing same to adhere to the printed areas, the excess being removed.
3. Allowing the ink and grit mixture to cure.
4. Applying a further layer of ink by screen printing onto the originally printed areas and applying a second relatively fine grit carborundum to the freshly treated glass surface and removing the excess and allowing the second deposition of ink to cure.
5. Applying a matt grey or black ink again by screen printing to the printed and gritted areas, and 6. finally curing the glass pane so as to bond the carborundum by means of the paint to the glass.
Typically each curing step lasts for at least 8 hours and may typically be longer such as 12 hours.
In a preferred arrangement 180 grit carborundum is used as the coarse material and 400 grit carborundum as the relatively fine material.
Conveniently the preliminary ink includes an extender and a catalyst.
Preferably a resin ink is used.
Typically the excess grit applied to the pane of glass at each stage is removed by brushing or blowing or vacuuming.
Whatever method is used, preferably excess grit is retained for future use.
The invention also lies in a pane of glass when treated in accordance with the invention so as to form on at least one face thereof a pattern of lines or areas which visually correspond to lead strips.
The invention is not limited to the application of the carborundum and ink to a single face but includes a pane of glass having the carborundum and ink layers applied to selected areas of both faces of a pane of glass.
Conveniently care is taken to ensure correct registry between the pattern of lines on the one face of the sheet of glass with those on the other.
The invention is also applicable to the mounting of a second sheet of glass in close proximity to but spaced from the treated sheet of glass to form a so-called double glazed unit which may be a socalled sealed double glazed unit.
The invention also lies in the provision of simulated leaded light strip on the external faces of two sheets of glass so arranged together.
1. A method of producing simulated leaded light effects on window glass comprising the steps of: i) screen printing onto a sheet of glass a pattern of lines of a preliminary ink which will serve as an adhesive, ii) applying to the treated glass surface a relatively coarse dry bulking agent and causing the letter to adhere to the printed areas, the excess being removed, iii) allowing the ink and bulking agent to cure, iv) applying a further layer of ink by screen printing onto the originally printed areas and applying a second relatively fine dry bulking agent to the freshly treated glass surface, removing the excess and allowing the second deposition of ink and bulking agent to cure, v) applying a matt grey or black ink by screen printing to the printed and gritted areas, and vi) finally curing the glass pane so as to bond the bulking agent by means of the ink to the glass.
2. A method as claimed in Claim 1, wherein 180 grit carborundum is used as the relatively coarse dry bulking material and 400 grit carborundum as the relatively fine dry bulking material.
3. A method as claimed in Claim 1 or Claim 2, wherein the preliminary ink includes an extender and a catalyst.
4. A method as claimed in Claim 3, wherein the preliminary ink is a resin ink.
5. A pane of glass treated by the method of any one of claims 1 to 4 so as to form on at least one face thereof a pattern of lines or areas which visually correspond to lead strips.
6. A pane of glass as claimed in Claim 5, which has been treated on both faces thereof.
7. A sealed double-glazed unit, wherein the external faces of the two glass panes are treated by a method as claimed in any one of claims 1 to 4.
