Properties
Unlike theatrical fog, which is typically intended to be dense and/or opaque, haze is generally very light and subtle. These properties allows a venue to be filled with haze prior to or during an event without creating an overtly distracting cloud. Haze typically has a substantially longer persistence ("hang time") than conventional theatrical fog. While conventional fog will hang in the air for several minutes, a haze effect filling the same volume of space can last upwards of an hour to several hours or more, depending on the size of the venue and the amount of ventilation.
The fluid used in haze machines to generate the effects are either oil or water-based. Most oil-based haze fluids use a mineral oil base, while water-based fluids use either a glycol or glycerol base. Although both formulations of fluid are referred to as haze fluid, the different formulations are neither compatible nor interchangeable. Glycol/water haze fluid is sometimes referred to as "water based haze" for the purposes of disambiguation.

Famous quotes containing the word properties:
“The reason why men enter into society, is the preservation of their property; and the end why they choose and authorize a legislative, is, that there may be laws made, and rules set, as guards and fences to the properties of all the members of the society: to limit the power, and moderate the dominion, of every part and member of the society.”
—John Locke (1632–1704)
“A drop of water has the properties of the sea, but cannot exhibit a storm. There is beauty of a concert, as well as of a flute; strength of a host, as well as of a hero.”
—Ralph Waldo Emerson (1803–1882)
