How do I date an oil lamp?

Dating relies on examining the burner mechanisms, collar types, and base materials alongside stylistic cues. Victorian examples often feature marked brass burners and heavy cast metal columns. Changes in patent dates stamped onto the brass winding wheels provide precise chronological markers for assembly.

Were these lamps converted to electricity?

Many surviving oil lamps retain their original burners, fonts, and wick mechanisms rather than undergoing conversion. This preserves their authentic 19th-century mechanical configuration. Collectors generally prefer examples that keep their original oil lamp hardware intact over electrified adaptations.

How do I clean cranberry glass shades?

Cleaning requires warm water and mild washing liquid applied with a soft cloth to protect the delicate etched surfaces. Harsh abrasives must be avoided entirely to prevent scratching the glass. Brass mounts should be treated separately with appropriate metal polish while taking care not to stain the glass.

What is the difference between ruby and cranberry glass?

Cranberry glass typically displays a lighter, pinker hue reminiscent of fruit juice, whereas ruby glass offers a deeper, more saturated crimson tone. Both colours were achieved using similar metallic oxide additives during manufacture. Victorian makers often used the terms interchangeably depending on the intensity of the molten batch.
