How do I measure for a replacement shade?

Measure the external diameter of the fitter rim at the base where it inserts into the brass gallery ring. Matching this measurement ensures the shade sits securely within the burner mount. Take care to measure the widest body diameter as well to ensure the glass clears any adjacent structural parts of the lamp frame.

Were these shades used with paraffin or kerosene?

The terms paraffin and kerosene describe the same hydrocarbon fuel utilised in domestic lamps from the mid nineteenth century onwards. These glass shades were designed specifically to withstand the heat generated by these oil burners. Different burner types, such as single or double wick systems, dictated the volume of heat the glass needed to endure during regular evening use.

How do I clean an antique glass shade?

Wash the glass gently in warm water using a mild, non-abrasive detergent and a soft cloth. Avoid submerging painted or gilded surfaces for extended periods to protect the antique decoration. Dry the piece thoroughly with a lint-free cloth before returning it to the brass gallery of the lamp.

How can I tell Victorian from Edwardian shades?

Victorian examples frequently display ornate Rococo Revival influences, rich cranberry hues, and heavy hand-painted floral or figural enamel work. The forms tend toward elaborate shapes and deep colours. Edwardian pieces often reflect simpler lines, including opaline glass finishes and Art Nouveau motifs with flowing organic contours and lighter pastel palettes.
