Description: | All brass holder for limelight with oxygen and hydrogen gas inlet tubes, burning nozzle, hand operated adjustment for racking out and rotating limelight specimen in flame. Accompanied by sample of lime (CaO) sitting on holder
"The study of the nature of light and the application of optics has formed an important part of the natural philosophy syllabus for the past 250 years. It is a subject with both practical and deeply philosophical aspects. This limelight is unusual in our collection in being donated by a former member of staff and accepted because of its relevance to a major teaching theme. The device is essentially an oxyhydrogen burner, fed with gas from two reservoirs, whose very hot flame is directed onto a lump of lime (CaO, not present) placed on the central spiggot. The adjustable mechanism allows the lime to be rotated and the distance from the flame to be altered for maximum effect."
