Evoking vintage schoolhouse glass, Petersburg features a mouth-blown glossy opal diffuser. To create this elaborate shape, a skilled artisan works molten glass into a special form called a "paced mold," which is simultaneously turned by an assistant. With careful timing, the team produces a seamless piece of beautifully detailed glasswork.Traditional StyleFinish: Old BronzeMaterial: SteelShade Bottom Width: 12.25"W Shade Height: 7"HShade/Diffuser Color: OpalShade/Diffuser Material: GlassShade Top Width: 4"WBulbs: 1 x 100 Watt E26 Medium BaseDimensions: 12.75"W x 10"HDamp Rated
