A less-expensive ingredient than titanium dioxide that fills out and extends the pigment's capabilities Extender cannot be used without pigment Some common extenders are clays, calcium carbonate, and silica
Ingredients added to paint to increase coverage, reduce cost, achieve durability, alter appearance, control rheology and influence other desirable properties Less expensive than prime hiding pigments such as titanium dioxide Examples: barium sulphate, calcium carbonate, clay, gypsum, silica, talc May also improve coating performance

Generally a mechanical device, often spring-loaded and concealed in a decorative cup below the lamp suspension hook, for pulling a lamp downwards from the ceiling, having it hold at the desired level (for lighting, filling, extinguishing), and then be returned to its "normal" burning location Older types relied on weights, later ones had spring loaded cable systems concealed in a long stem
