Sterno

Sterno ("canned heat") is a fuel made from denatured and jellied alcohol. It is designed to be burned directly from its can. Its primary uses are in the food service industry for buffet heating and in the home for fondue and as a chafing fuel for heating chafing dishes. Other uses are for camp stoves and as an emergency heat source (deer-blind). It is also a popular fuel for use with toy and model steam and other external combustion engines. Sterno cans were sometimes taken on trips and used to heat pressing/curling irons & hot combs, for hairstyling, when travelers were staying at hotels, etc. and not located near salons which offered certain services that required these styling tools.
