For a carbide lamp to work, there is two chemical reactions that have to take place. The first chemical reactions occurs from calcium carbide and water. The second, is between calcium oxide and water. The reactions produce a very bright but gentle flame. The amount of water that combines with the calcium carbide and calcium oxide to produce this flame, is initially set by the operator of the lamp.

Is tungsten tougher that tungsten carbide?
No. Tungsten is an element, where as tungsten carbide is an alloy, or a mixture of elements (tungsten, nickel, tantalum, niobium, titanium, and chromium). Tungsten carbide is much easier to work into styles and designs, but does not change the hardness of the metal.
What is the natural source for calcium carbide miners gas?
Calcium carbide is a chemical compound that reacts with water to produce acetylene gas, which is combustible and is used in mining lamps. The gas also encourages fruit growth in plants such as pineapples. Calcium carbide is used in making steel, PVC, signal flares and some old-fashioned fireworks, in addition to mining. Calcium carbide is man-made. It is produced in a 2000º electric arc furnace. There is no "natural source" for the substance. You cannot go dig it up somewhere. If you could, it would be a clear or bluish crystal, rather soft, with an unpleasant odor. I would go into the science of it in more depth, but the foregoing answers the question asked and you don't need to be a chemistry major to understand it. :) +++ I'd be very surprised if miners still use acetylene lamps! They were used by miners in gas-free ground (usually metal-ore mines and underground stone quarries) many years ago. They were used by many cavers until electric lamps (usually ex-colliery) became common in the 1960s, then had a brief flurry of popularity again in the 1980s-90s when developments in caving techniques and equipment meant the electric mining lamps were no longer safe to use due to their liquid electrolytes . Now acetylene lamps are pretty well obsolete, displaced in mining and in caving by l.e.d lamps; and suppliers of calcium carbide are becoming hard to find.
Is silicon carbide ionic?
No. Silicon carbide is covalent.
What is the common name of silicon carbide?
silicon carbide
What is the valency of carbide?
The valency of Carbide is -4. Yet for some unknown/unexplained reasons Calcium Carbide is CaC2 and not Ca2C.
Can calcium carbide be an alternative to oil lamps?
Calcium carbide lamps have been used (historically in mines) to create light by immersing calcium carbide in water to produce acytelene gas, which burns and creates light. Although they work as lamps, the gas produced by them makes them less safe than oil lamps, and as such they were usually only used in industrial lighting rather than in homes. Electrical lighting is usually safer than either oil or carbide lamps because there is less danger of fire.
Did miners hat use calcium carbide lights?
Carbide lamps, or acetylene gas lamps, are simple lamps that produce and burn acetylene (C2H2) which is created by the reaction of calcium carbide (CaC2) with water (H2O). ... Portable acetylene gas lamps, worn on the hat or carried by hand, were widely used in mining in the early twentieth century.
What are some of the uses for carbide?
Calcium carbide is used in steelmaking as a fuel and a powerful deoxidizer. It is also used in the production of carbide lamps but has been relatively phased out of all mining operations.
What kind Of Carbide is needed for lamp?
Calcium Carbide is used in "Carbide Lamps". Water, added dropwise to Calcium Carbide yields acetylene plus calcium hydroxide. Acetylene is extremely flammable, giving a colorless flame. The calcium hydroxide present gives the flame its visibility. Calcium Carbide is used in "Carbide Lamps". Water, added dropwise to Calcium Carbide yields acetylene plus calcium hydroxide. Acetylene is extremely flammable, giving a colorless flame. The calcium hydroxide present gives the flame its visibility.
What tools are used for shaft mining?
The tools that are used in shaft mining are a cradle, a windlass, a bucket and a pick.shovels, carbide lamps, tipples, mules and ponies.

How did a calcium carbide mining pump work?
it worked somehow, some-way

How do adjustable height lamps work?
The working principle behind the adjustable height lamps is very simple. The adjustable height lamps enables the users to adjust the height of the lamps to their preferred height.
What is Carbide?
"Carbide" as used in "Carbide Drills" and "Carbide Saws" is the alloy Tungsten Carbide. Chemically the material is either Tungsten Carbide (WC) or Tungsten diCarbide (WC2). Carbide is used because of its hardness.
What bit do you use to drill bluestone?
A carbide tipped masonry bit would work well.
Is silicon carbide ionic?
No. Silicon carbide is covalent.
