A genuine vintage glass shade — whether a marbled Art Deco plafonnier, an opaline bowl, or a period coolie — is a remarkably durable object. Glass that has survived 80 or 100 years intact will, with a little care, survive another century. The enemies are not time but impact, inappropriate cleaning, and neglect.
This guide covers everything you need to keep a reclaimed glass shade looking its best.
Routine Cleaning
For regular dusting, a soft, dry microfibre cloth is all you need. Avoid feather dusters — they tend to move dust around rather than lift it, and the quills can scratch softer glass surfaces.
For a more thorough clean, remove the shade from its fitting if possible and wash by hand in warm water with a small amount of mild washing-up liquid. Use a soft cloth or sponge — never anything abrasive. Rinse thoroughly and dry with a clean, lint-free cloth before refitting.
Avoid dishwashers entirely. The combination of high heat, harsh detergents, and mechanical agitation is damaging to period glass and can affect the marbling on opaline pieces.
What to Avoid
A few things that are genuinely harmful to reclaimed glass shades:
- Acidic cleaners — vinegar-based products, limescale removers, and anything with a low pH can etch the surface of opaline glass over time
- Ammonia-based glass cleaners — products like standard window spray can dull the surface of period glass with repeated use
- Abrasive cloths or pads — even mildly abrasive materials will scratch glass that has softened slightly with age
- Sudden temperature changes — don't move a cold shade into a very warm room and clean it immediately; allow it to acclimatise first
- High-wattage incandescent bulbs — the heat generated by old-style bulbs is one of the most common causes of stress cracking in enclosed glass shades. Use LED bulbs rated for enclosed fittings
Handling
Most damage to vintage glass happens during handling, not use. When removing or refitting a shade:
- Support the bowl from underneath with both hands — never grip it by the rim alone
- Work over a padded surface in case of slips
- Check that the bowl hooks are secure and correctly positioned before releasing the shade
- If the shade feels loose in its hooks, don't leave it — an uneven fit puts stress on the glass that will eventually cause a crack
Storing a Shade
If you need to store a glass shade — during a move or redecoration — wrap it individually in acid-free tissue paper or clean bubble wrap, and store it upright or on its side in a padded box. Never stack glass shades directly on top of one another, and avoid storing them where they might be knocked.
Keep stored glass away from extremes of temperature and humidity. A dry, stable environment is ideal — attics and garages, which can get very hot or very cold, are not.
Chips and Damage
Small chips on the rim are the most common form of damage on period glass shades. If a chip appears, the sharp edge can be carefully smoothed — this is the same diamond grinding process we use during restoration, as described in our guide to how we restore and wire a vintage Flycatcher, and it's worth having done properly rather than leaving a sharp edge that could worsen or cause injury.
Cracks are more serious. A hairline crack that doesn't extend to a fixing point or the rim may be stable for years; one that does should be assessed before the shade is used further. If in doubt, get in touch — we're happy to advise.
Long-Term Care
Beyond cleaning and careful handling, the best thing you can do for a reclaimed glass shade is use it. Glass that is regularly cleaned and properly lit — with appropriate bulbs, in a secure fitting — will remain in excellent condition indefinitely. These pieces were made to last, and with a little attention, they will.
