Two lamps with the same light bulb can have a completely different effect. Not because of their shape, but because of the material the light has to pass through. Those who understand what alabaster, glass, and marble do with light will make their selection faster and regret it less often.
Alabaster: the surface that glows from within
Alabaster is a fine-grained gypsum stone, slightly translucent and milky veined. Light is not transmitted through it, but scattered: a point of light becomes a luminous surface. Therefore, an alabaster lamp practically never glares, even if you look directly into it, and therefore its light appears warmer than the light color of the lamp suggests. The veining becomes visible, each piece glows a little differently.
Alabaster belongs where the light source is in the field of vision: above dining tables, in hallways, in rooms with low ceilings.
Care: Alabaster is soft and sensitive to water. Dust dry, no damp cloths, no cleaners. Moisture leaves dull spots that remain.
Glass: it's all about the surface
Clear glass allows light to pass through unhindered. This is desirable if the light source itself is beautiful, and disturbing if it is not: you see the filament, and it glares. Clear glass lamps therefore belong above head height or on dimmed circuits.
Frosted or satinized glass scatters light similarly to alabaster, but more evenly and cooler, without veining. Ribbed or hammered glass breaks the light into many small reflections, which looks lively but creates restless shadows on walls and ceilings.
Care: uncomplicated, can be wiped damp. Always switch off lamps first and let them cool down; cold water on hot glass can cause cracks.
Marble: not light, but mass
Marble is slightly translucent in thin slabs, but in furniture construction it is primarily one thing: heavy and reflective. Polished marble reflects light and makes a room brighter. Brushed or honed marble does not do this; it absorbs light and appears calmer. For tabletops in bright rooms, matte is almost always the better choice; polished creates glare spots.
Care: Marble is calcareous and reacts to acid. Wine, lemon, and vinegar leave dull etch marks that no cleaner can remove. Coasters are not a precaution here, but a necessity.
And the metal around it
The material of the fitting also determines the light color. Antique brass reflects light warm and slightly yellowish, polished brass harder and shinier, bronze absorbs reflections and appears subdued, chrome and nickel reflect light cool and neutral. If you combine a warm alabaster lamp with a chrome fitting, you get two lighting moods in one object.
Briefly summarized
| Material | Effect | Well suited for |
|---|---|---|
| Alabaster | softly diffused, warm, glare-free | Dining table, hallway, low rooms |
| Clear glass | direct, sparkling, glaring | high rooms, dimmed circuits |
| Satinized glass | evenly diffused, cooler | Work areas, bathroom |
| Polished marble | reflective, bright | dark rooms |
| Matte marble | light-absorbing, calm | bright rooms, dining tables |
You can find lamps made of these materials under Lamps, suitable objects under Accessories.
Frequently Asked Questions
Why doesn't an alabaster lamp glare?
The stone scatters the light instead of letting it pass through. The point of light becomes a luminous surface that can be looked at directly.
How is alabaster cleaned?
Only dust dry. Alabaster is sensitive to water; moisture leaves permanent dull spots.Polished or matte for marble tables?
In bright rooms, matte, which avoids glare spots. Polished is worthwhile where additional light is to be reflected back into the room.
