Patent ID: 8728634

Claim:
An oven transparency, comprising: a plurality of uncoated glass substrates; a single coated glass substrate having a first major surface and a second major surface; a first coating having a thickness in the range of 4,000 Å to 5,000 Å provided over at least a portion of the first major surface of the coated glass substrate, the first coating comprising: a first coating layer comprising a gradient layer comprising silica and tin oxide having a thickness in the range of 1,000 Å to 1,200 Å, where said gradient layer has a continuously changing composition as distance increases from an interface of said gradient layer and said single coated glass substrate; and a second coating layer comprising fluorine doped tin oxide having a thickness in the range of 3,000 Å to 4,000 Å; and a second coating provided over at least a portion of the second major surface, of the coated glass substrate the second coating comprising: a first dielectric layer having a thickness less than or equal to 500 Å comprising a zinc stannate layer and a zinc oxide layer; a first metallic layer having a thickness in the range of 70 Å to 110 Å over the first dielectric layer; a second dielectric layer having a thickness in the range of 500 Å to 1,000 Å over the first metallic layer and comprising a first zinc oxide layer, a zinc stannate layer, and a second zinc oxide layer; a second metallic layer having a thickness in the range of 80 Å to 200 Å over the second dielectric layer; and a topcoat over the second metallic layer consisting of a single layer comprising zinc oxide; and a protective coating over the topcoat, wherein the oven transparency has a transmitted color selected from blue and greenish blue, wherein said first coating defines a first side of said coated glass substrate, and said second coating defines a second side of said coated glass substrate, wherein the first side has a reflected color defined by −10 ≦a*≦0 and −30 ≦b*≦−5, wherein the second side has a reflected color defined by −10 ≦a*≦0 and −30 ≦b*−5, and wherein at least one of the first side and the second side has an L* greater than or equal to 40.
