Alcohol burners are preferred for some uses over Bunsen burners for safety purposes, and in laboratories where natural gas is not available. Their flame is limited to approximately 5 centimeters (two inches) in height, with a comparatively lower temperature than the gas flame of the Bunsen burner.
The alcohol-water mixture flame can be hard to detect, so sodium chloride can be added to give the flames an orange-yellow color. [1] [3] For safety purpose, a water tray should be prepared for emergency use in case a paper banknote caught a fire, and flammable and combustible materials should not be kept or put near the flame.

Burning fluid lamps had two long tapering wick tubes that looked like the letter V. The tubes had caps resembling thimbles to extinguish the light and prevent evaporation when the lamp was not in use. Camphine lamps had a single fixed wick with a flame spreader and a central draft system. [6] One type of camphine lamp was called a Vesta lamp. [23]
The procedure uses different solvents and flames to view the test flame through a cobalt blue glass or didymium glass to filter the interfering light of contaminants such as sodium. [12] Flame tests are subject of a number of limitations. The range of elements positively detectable under standard conditions is small.
Several laboratory experiments are capable of producing relatively pure gas as an end product, and it may be useful to demonstrate the chemical identity of that gas. Burning splints or glowing splints can be used to identify whether a gas is flammable , whether it is oxidising , or whether it is chemically inert .
Camphene / alcohol blends (at $.50 per gallon) were cheaper than whale oil ($1.30 to $2.50 per gallon) and lard oil (90 cents per gallon). It was about the same price as coal oil, which was the product first marketed as "kerosene." [5] In 1860, German inventor Nicolaus Otto uses ethyl alcohol as a fuel in an early internal combustion engine. [6]

Jewelers and glassblowers engaged in lampwork have used the blowpipe since ancient times, with the blast being powered by the user's lungs. For small work, a mouth-blown blowpipe may be used with a candle flame or an alcohol lamp, with established techniques for applying oxidizing and reducing flames to the workpiece or
