Use the best polish obtainable for protecting and enhancing the beauty of antique furniture. Never have antique furniture sprayed. Restore scratched surfaces with an application of beeswax. Remember also, that strong sunlight fades old wood and sometimes cracks it. Always leave repairs to valuable furniture to a first-class restorer.
Cold water is best for rinsing but avoid plunging warm glass into cold water.
Pieces being rinsed should be lowered gradually into cold water. Dry with chamois leather or linen cloth. Do not expose valuable antique glass to extreme humidity. Glue can be used to join up broken glass, but usually expert advice on mending is advisable. Heat must especially be guarded against, therefore only lukewarm water with a small amount of detergent should be applied to ivory, and each piece needs to be dried immediately.
