## Abstract

A coated glass article, particularly for use as architectural glass, is gold in appearance. The coated glass article includes a glass substrate with an iron oxide coating deposited thereover, the iron oxide coating comprising primarily iron oxide in the form Fe2O3. The coated glass article has an a* value between about −5 and about 10, and a b* value between about 10 and about 40, for both transmitted and reflected light.

## Claims

### Claim 1

An architectural glazing comprising a light transmitting coated glass article comprised of a glass sheet having an iron oxide coating deposited thereon, the iron oxide coating comprising iron oxide primarily in the form Fe2O3, wherein the iron oxide coating contains only iron and oxygen and possibly trace contaminants, and wherein the coated glass article is gold in appearance for both transmitted and reflected light, and has an a* value between about −5 and about 10, and a b* value between about 10 and about 40, for both transmitted and reflected light.

### Claim 2 (depends on 1)

The architectural glazing according to claim 1, further comprising a second glass sheet spaced apart from the glass sheet having the iron oxide coating deposited thereon to form an IG unit.

### Claim 3 (depends on 1)

The architectural glazing according to claim 1, wherein the iron oxide coating is a chemical vapor deposition coating.

### Claim 4 (depends on 1)

The architectural glazing according to claim 1, wherein the glass sheet is a soda-lime float glass sheet.
