E-cigarettes do not turn on by trying to "light" the device with a flame. [11] The e-liquid reaches a temperature of roughly 100-250 °C within a chamber to create an aerosolized vapor. [7] Variable voltage devices can raise the temperature. [30] A glycerin-only liquid vaporizes at a higher temperature than a propylene glycol-glycerin liquid. [30]
Silver spoons self-sanitize due to the oligodynamic effect. The oligodynamic effect (from Greek oligos, "few", and dynamis, "force") is a biocidal effect of metals, especially heavy metals, that occurs even in low concentrations.

E-cigarette makers do not fully disclose information on the chemicals that can be released or synthesized during use. [1] The chemicals in the e-cigarette vapor can be different than with the liquid.

Some companies manufacture belt buckles or novelty paper weights that function as brass knuckles. [25] Brass knuckles made of plastic, rather than metal, have been marketed as "undetectable by airport metal detectors ...
Copper, steel, brass, iron, and nickel are commonly used metals in bimetallic strips. [6] Metal alloys have been used in bimetallic strips as well, such as invar and constantan . Material selection has a significant impact on the working temperature range of a bimetallic strip, with some having a temperature limit up to 500°C, with others only ...
Metal fume fever, also known as brass founders' ague, brass shakes, [1] zinc shakes, galvie flu, galvo poisoning, metal dust fever, welding shivers, or Monday morning fever, [2] is an illness primarily caused by exposure to chemicals such as zinc oxide (ZnO), aluminium oxide (Al 2 O 3), or magnesium oxide (MgO) which are produced as byproducts in the fumes that result when certain metals are ...
Cutaway diagram of a No. 10 delay switch. One type, the British Number Ten Delay Switch (official name, "Switch, No. 10, Delay" and often referred to as a "timing pencil"), was made of a brass (or in later versions aluminium) tube, with a copper section at one end which contained a glass vial of cupric chloride (the liquid was widely and erroneously reported to be sulfuric acid [original ...
