Abstract
Abstract A process and the resulting article for fabricating a customized glass greeting card wherein two sheets of glass with a design etched there on are each placed in a frame and hinged together on one side thereof to resemble a folded card. Unetched areas of the glass appear relatively dark compared with translucent areas whether the frames are open or closed together.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
160 words
A process for customizing glass greeting cards, comprising the steps of: (a) applying a design to first and second sheets of clear glass by covering the glass with an impermeable substance where the design is to appear; (b) etching the glass of the first and second sheets where not covered by means of an etching chemical to impart a translucent finish thereto, whereupon the etching chemical is removed; (c) removing the design to expose clear, unetched glass; (d) placing each sheet of glass in a frame and hinging the frames together on one side thereof to resemble a folded card whereby the clear unetched glass transmits light and appears dark relative to the translucent areas of glass which reflect light and appear relatively light and so resembles a printed card whether the hinged frames are open or closed together and further whereby only the design on the top sheet of glass is visible when the hinged frames are closed together.
Claim 2
Dependent Claim
160 words
A process for customizing glass greeting cards, comprising the steps of: (a) applying a design to first and second sheets of clear glass by covering the glass with an impermeable substance where the design is to appear; (b) etching the glass of the first and second sheets where not covered by means of an etching chemical to impart a translucent finish thereto, whereupon the etching chemical is removed; (c) removing the design to expose clear, unetched glass; (d) placing each sheet of glass in a frame and hinging the frames together on one side thereof to resemble a folded card whereby the clear unetched glass transmits light and appears dark relative to the translucent areas of glass which reflect light and appear relatively light and so resembles a printed card whether the hinged frames are open or closed together and further whereby only the design on the top sheet of glass is visible when the hinged frames are closed together.
Claim 3
Dependent Claim
44 words
A process according to claim 1 wherein the step of applying the design to the sheets of glass comprises applying an adhesive sheet to the glass and then removing parts of the sheet to leave other parts defining the design adhering to the glass.
Claim 4
Dependent Claim
45 words
A process according to claim 1 wherein the step of applying the design to the sheets of glass comprises the step of placing a mesh screen in intimate contact with the glass, the screen having permeable and impermeable areas thereon corresponding to the desired design.
Claim 5
Dependent Claim
61 words
A process according to claim 3 wherein the step of etching the exposed glass comprises the further steps of: (a) applying an etching chemical to the screen and squeezing the chemical through the permeable areas of the mesh onto the glass; and, (b) removing the etching chemical from the glass after a pre-determined period of time to expose the etched glass.
Claim 6
Dependent Claim
95 words
A process according to claim 3 wherein the step of etching the exposed glass comprises the further steps of: (a) producing a transparency having an opaque design thereon; (b) producing a screen wherein the design comprises the permeable areas of the screen; (c) applying an etching chemical-resistant paint through the permeable areas of the screen onto the glass and then removing the screen from the glass; (d) applying the etching chemical to the entire sheet of glass; and, (e) removing the etching chemical and resistant paint to expose a clear design on a translucent background.
Claim 7
Dependent Claim
115 words
A customized glass greeting card comprising: (a) first and second sheets of glass having a design thereon formed by areas of transparent and etched, translucent surfaces; (b) first and second frames hinged together on one side thereof for holding said first and second sheets of glass, respectively, so as to resemble a folded card; whereby the clear, etched glass transmits light and appears dark relative to the translucent areas of the glass which reflect light and appear relatively light and so resemble a printed card whether the hinged frames are open or closed together and further whereby only the design on the top sheet of glass is visible when the hinged frames are closed together.
Claim 8
Dependent Claim
115 words
A customized glass greeting card comprising: (a) first and second sheets of glass having a design thereon formed by areas of transparent and etched, translucent surfaces; (b) first and second frames hinged together on one side thereof for holding said first and second sheets of glass, respectively, so as to resemble a folded card; whereby the clear, etched glass transmits light and appears dark relative to the translucent areas of the glass which reflect light and appear relatively light and so resemble a printed card whether the hinged frames are open or closed together and further whereby only the design on the top sheet of glass is visible when the hinged frames are closed together.
