Art glass shades complement the varying degrees of lighting designs, whether plain, restrained, or delicately detailed. These shades all emerge from humble clumps of glass.The Aurene Optic Tulip Shade begins as a gold lump, which is first rolled in a round wood block to prepare it to be mouth blown into a "ribbing" mould. Glass is blown into a rough tulip shape, and the bottom of the glass is burst to create a wide rim, which is placed onto a fluting mold for dimpling. After more shaping and finishing (and while still quite hot) the shade is sprayed with tin chloride, giving it an iridescent, light-refracting finish.After it's completely cooled in an annealing oven, the fitter is ground off with a diamond saw and the shade is signed.
