Campingaz
Campingaz (pronounced as 'camping gas', from the French), formerly Camping Gaz, is a brand of compressed, mixed butane/ propane gas supplied in small, lightweight, disposable cans designed for use as a fuel while camping and caravanning. The fuel gas is compressed to a liquid and sold in characteristic blue metal containers. For the larger refillable cylinders the contents are butane. The brand name is also used on appliances manufactured for use with the gas: cookers, lanterns, heaters, grills, refrigerators, etc. as well as more general camping equipment such as sleeping bags.
