Simulated etched glass window and method

Claim 2

In an insulated glass window including two spaced apart inner and outer panes of glass with aligned outer edges around an enclosed space and each pane having an inside and outside surface and a sealing strip adjacent the outer edges and on the inside surfaces between the panel, spacers adjacent the sealing strip within the enclosed space with perforations facing the enclosed space and a drying agent in the enclosed space which removes moisture from the enclosed space the improvement for simulating etched glass which comprises: a small amount of dried ink and a clear varnish mixture which adheres to the glass provided on the inside surface of the inner or outer pane as a translucent appearing, frosted design, wherein the varnish constitutes at least about 99 percent by volume of the mixture wherein the enclosed space is substantially free of moisture which affects the dried mixture exposed to the enclosed space.

Claim 3

The window of claim 1 wherein the mixture of white ink and a different color ink which have been mixed together as a liquid and then mixed with the varnish as a liquid.

Claim 4

The window of claim 2 wherein the different color ink is blue.

Claim 5

The window of claim 3 wherein the ratio of white ink to blue ink is between about 75 to 25 and 25 to 75 percent by volume.

Claim 6

The window of claim 4 wherein the amount of the white ink and of the blue ink together to varnish is between about 20 and 40 cc of the inks per 4.546 liters blended together as the liquids which are dried to form the dried mixture.

Claim 7

The window of claim 1 wherein the dried mixture is in the form of a screen print on the pane.

Claim 8

The window of claim 6 wherein a screen having a mesh size of between about 200 and 300 mesh is used to produce the screen print.

Claim 9

The window of claim 1 wherein the spacers have a hollow rectangular cross-section with the drying agent inside the spacers.

Claim 10

In a method for forming an insulated glass window including two spaced apart inner and outer panes of glass with aligned outer edges around an enclosed space and each pane having an inside and outside surface and a sealing strip adjacent the outer edges and on the inside surfaces between the panes, spacers adjacent the sealing strip within the enclosed space with perforations facing the enclosed space and a drying agent in the spacer which removes moisture from the enclosed space, the improvement for simulating etched glass which comprises: (a) applying a small amount of a liquid ink and clear varnish mixture which adheres to the glass pane on the inside surface of at least one of the inner or outer panes to provide a translucent appearing, frosted design; (b) drying the liquid mixture on the pane to form a dried mixture which adheres to the glass pane, wherein the varnish constitutes at least about 99 percent by volume of the mixture and wherein the sealing strip is unaffected by the dried mixture over time; and (c) forming the insulated glass window wherein the enclosed space is substantially free of moisture which affects the dried mixture exposed to the enclosed space.

Claim 11

In a method for forming an insulated glass window including two spaced apart inner and outer panes of glass with aligned outer edges around an enclosed space and each pane having an inside and outside surface and a sealing strip adjacent the outer edges and on the inside surfaces between the panes, spacers adjacent the sealing strip within the enclosed space with perforations facing the enclosed space and a drying agent in the spacer which removes moisture from the enclosed space, the improvement for simulating etched glass which comprises: (a) applying a small amount of a liquid ink and clear varnish mixture which adheres to the glass pane on the inside surface of at least one of the inner or outer panes to provide a translucent appearing, frosted design; (b) drying the liquid mixture on the pane to form a dried mixture which adheres to the glass pane, wherein the varnish constitutes at least about 99 percent by volume of the mixture and wherein the sealing strip is unaffected by the dried mixture over time; and (c) forming the insulated glass window wherein the enclosed space is substantially free of moisture which affects the dried mixture exposed to the enclosed space.

Claim 12

The method of claim 9 wherein the liquid ink and varnish mixture is applied on the pane in the form of a screen print on the glass.

Claim 13

The method of claim 10 wherein a screen having a mesh size between about 200 and 300 mesh is used to produce the screen print.

Claim 14

The method of claim 9 wherein the ink is a mixture of a white ink and a different color ink.

Claim 15

The method of claim 12 wherein the different color ink is blue.

Claim 16

The method of claim 13 wherein the ratio of liquid white ink to blue ink is between about 25 percent and 75 percent by volume and wherein the inks are mixed together and then mixed with the liquid varnish before being applied.

Claim 17

The method of claim 9 wherein the mixture is air dried for 4 to 6 hours at 60° to 80° F. and held for at least 24 hours prior to forming the insulated glass window.
