One classic glass that should make its way into every home barware stash is a copper mug (or four, since your friends will want a cocktail in one, too). Copper has been prized for centuries for its heat and cold conducting ability. The best cookware in the world has some copper in it.
What this means for your Moscow Mule is: your copper mug gets frosty cold when it holds this ice-cold cocktail. Most copper mugs aren't 100% copper, but are lined with copper on the outside. High quality cookware is partially copper for the same reason- copper is reactive to acidity in cocktails and in food, and can leach copper into your food or drink. In small quantities copper is fine, even important for human health, but think before drinking every cocktail out of a copper mug and sending your system out of whack.
Nevertheless, copper mugs are an essential member of the cocktail glass family. Just remember when buying to look for one with a handle- no handle means the glass could get uncomfortably cold with your favorite beverage in it.
