What fuels are used in lampworking?
Most artists doing lampwork use a mixture of oxygen and propane. Some use just propane alone which produces a cooler flame. Some use MAPP gas, which is a mixture of methacetylene (CH3C2H) and propadiene (CH2CCH2) with traces of other gasses added as ‘stabilizers’. MAPP gas produces a hotter flame than propane alone, but less than oxy-propane. Popular torch brands are the Hot Head (cheap, portable, uses MAPP gas) and the Minor burner (oxy-propane, industry-standard, but more expensive).
