I think there were three basic kinds: the large ones which were self supporting and which gave background light to a large room; the smaller ones which people carried around with them as they moved about in the dark; and the candelabra type, which were suspended from above. They were commonly made of pewter, iron and brass.

Answer 2

Wrought iron usually. Quite often very structured, i.e symetrical. Decorative holders usually depicted plants or vines.
