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 €œpaced 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/Diffuser Color: OpalShade/Diffuser Material: GlassBulbs: 1 x 75 Watt E26 Medium BaseDimensions: 9.5"W x 8"HDamp Rated
