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: 16"W Shade Height: 10"HShade/Diffuser Color: OpalShade/Diffuser Material: GlassShade Top Width: 5.5"WBulbs: 1 x 150 Watt E26 Medium BaseDimensions: 16"W x 12.5"HDamp Rated
