Abstract
ABSTRACT A method for applying a pattern (10) to a glass panel for simulating a Georgian style lattice window comprises applying a surface coating composition to form bands (14,15) of the pattern (10) by airless spraying through a nozzle (20). The surface coating composition comprises a mineral based ink of the type suitable for ceramics applications which is provided in powder form of particle sizes in the range of (1) micron to (7.6) microns. The mineral based ink is mixed with a liquid solvent for agglomerating the particles, and colour pigment is added as appropriate. The surface coating composition is applied to an inner surface (11) of the glass panel (3) to a depth of approximately (200) microns to form the bands (14,15). The surface coating composition of the bands (l4,l5) is then dried, and the panel (3) is then toughened at a toughening temperature of the order of (700°)C for a time period of approximately one and a half minutes, which also causes the surface coating composition forming the pattern (10) to fuse to the glass.
Description
The present invention relates to a method for applying a pattern to a glass panel, and the invention also relates to a glass panel having a pattern applied thereto by the method.
There are many instances in which it is desirable to apply a pattern to a glass panel, and in particular, there are many instances where it is desirable to apply the pattern to the glass panel so that the pattern is clearly defined by well defined edges, rather than by feathered edges. For example, in the provision of Georgian and Tudor style lattice type windows, it is desirable that the criss-cross bars of the pattern simulating the lattice appear to be genuine criss-cross bars. In the manufacture of double glazed windows where the window pane is formed by two panes of glass, namely, an inner and an outer pane which are spaced apart one from the other, it is known to locate spacer bars which are arranged in a criss-cross manner between the inner and outer glass panes for simulating a Georgian or Tudor style lattice. Typically, such spacer bars are of metal, for example, hollow box section aluminium, and are of thickness corresponding to the spacing between the inner and outer glass panes, which typically, is 12mm. The width of the bars depends on the desired width of the criss-cross members being simulated, and can range from 6mm, in the case of a Tudor style window, to up to 28mm in the case of a Georgian style window.
However, the problem with simulating Georgian and Tudor style lattice windows with -..aa
Claims (5)
1. A method for applying a pattern to a glass panel, the method comprising the steps of applying mineral based ceramic ink to the glass panel to form the pattern, wherein the mineral based ink is applied by airless spraying, and the mineral based ink comprises an agglomerating agent for agglomerating the molecules of the mineral based ink together.
2. A method as claimed in Claim 1 in which the mineral based ink is in powder form prior to mixing with the agglomerating agent, and the agglomerating agent is a solvent.
3. A method as claimed in Claim 1 or 2 in which the mineral based ink is applied by airless spraying through a nozzle having a circular bore, which converges in one plane for defining an elongated nozzle outlet, and diverges in a plane at right angles to the plane in which the bore converges, and the rate of diverging of the bore of the nozzle is such as to provide a jet of the mineral based ink to issue from the nozzle outlet in a fan shape of fan angle in the range of 5° to 40°.
4. A method for applying a pattern to a glass panel, the method being substantially as described herein with reference to and as illustrated in the accompanying drawings.
5. A glass panel having a pattern applied thereto by the method as claimed in any preceding claim.
