What are glass student shades for oil lamps?
Glass student shades are a traditional style of lampshade used on oil lamps. They capture the timeless elegance of 19th and early 20th century lighting. These period-correct shades were traditionally rendered in white opal glass, green cased glass, and hand painted floral designs. The two most common sizes are: 7" oil lamp shades and 10" oil lamp shades. They were used with a glass chimney to shield the flame from drafts.
How do glass student shades improve an oil lamp’s light?
The shape and color of a glass student shade improved the light output of an oil lamp. Rather than relying on the light from a flame inside a glass chimney alone, these shades spread the light over a broader area. Green cased glass, made with layers of green and white glass fused together, helped direct light downward for reading, sewing, and other close work.
Improved lighting made evening activities easier in 19th-century homes, allowing people to read and do handwork more comfortably after dark.
What parts hold a glass student shade on an oil lamp?
Whether oil-burning or converted to electricity, these lamps require a burner, chimney and tripod, spider or shade ring to support the glass student shade. Whichever type of shade holder is used, it must fit snugly onto the oil or electric burner. Tines around the burner’s outer edge hold the glass chimney in place.
How do you measure a glass student shade?
Student shades are primarily measured by their bottom diameter, known as the fitter. These shades are blown in molds, so glass thickness and exact fitter measurements can vary slightly. Although two common fitter sizes are 7 inches and 10 inches, the actual bottom diameter is often slightly smaller than the stated size. This slight variation is normal and is not a defect.
If your lamp already has a shade holder, measure it to determine the shade size needed.
If you need both a holder and a shade, use the lamp’s proportions as a starting guide: lamps with bases 9–10 inches tall typically use 10-inch fitter shades, while those with smaller bases 8–9 inches tall often use 7-inch fitter shades. Confirm the shade and holder measurements before choosing.
What styles of glass student shades are available?
Glass student shades come in a variety of colors, patterns, and finishes. Their surfaces may be smooth or feature raised designs, such as hobnail and melon patterns, while the top openings may have flat or crimped edges.
White glass shades offer a simple, neutral appearance that suits many lamp styles. Green cased glass shades, made with layers of green and white glass fused together, complement brass lamps and are closely associated with traditional student lamps. Hand-painted floral shades offer a more decorative look suited to Victorian-style interiors.
Although most often used on table lamps, glass student shades are also found on some hanging lights and floor lamps.
