Because of my article on torches in Art Jewelry, I have just received an inquiry about using MAPP gas for silver work. I use MAPP gas in small bottles with one of those hardware store burners, like the propane torch type. I only use it for annealing large articles and sometimes for casting. Supposedly it’s a little hotter than propane.

Choosing the right gas ensures the torch will burn at the desired temperature. When acetylene, hydrogen, propane, MAPP®, and natural gas are combined with oxygen, they achieve temperatures ranging from 3500°F to 6300°F, hot enough for most jewelry applications. Acetylene, like kerosene, is made from natural gas.

Yes, and it's very easy. I've made a bunch of silver castings at home using nothing more than a ceramic crucible with a pouring handle ($11.00 at a local lapidary shop) and an oxy/MAPP gas torch ($18 from Home Depot) to melt the silver. I later upgraded the torch to oxy/acetylene for faster melts and more gas economy, but oxy/MAPP works just fine. I've done melts as large as 3 oz. via this method with no …

Aug 09, 2007 · If MAPP gas and acetylene have almost the same flame temp, MAPP has more heat in it, MAPP gas is cheaper and safer to handle, and MAPP gas is ... to a much tinier point than any LP gas.

Mar 13, 2020 · MAPP (AKA MAP-Pro) gas burns at a higher temperature than butane and propane. Propane is the next step up and can be used for tasks like loosening rusted bolts. MAP-Pro is used for the more robust jobs like soldering copper pipes and heat treating knives.

MAPP is an acronym for methylacetylene-propadiene propane, which were its main ingredients, although it also contained iso-butane and butane.MAPP gas turned out to be less than ideal for welding steel because of its high hydrogen content, and it burned slightly too hot to be safe for soldering.
