Vaseline glass lighting is known for its distinctive translucent yellow-green hue and subtle fluorescence under UV light, created by the use of trace uranium oxide in the glass mix. Strongly associated with the Arts & Crafts movement, Vaseline glass was favoured for its handmade, organic qualities and soft diffusion of light.
Notable examples were produced by James Powell & Sons, later known as Whitefriars Glass, whose work features in many period pendants, sconces, and bespoke commissions from the late 19th to early 20th centuries. Often paired with copper or [wrought iron] mounts, these fittings remain highly sought after for their gentle tone and authentic period character.
