MAPP Gas No Longer Produced
On April 30, 2008, the Petromont Varennes plant closed its methylacetylene/propadiene plant. They were the only North American plant making MAPP gas, and the only legal supplier of trademarked MAPP gas in the world. This caused a widescale shortage, and many substitutes were introduced by the companies who had repackaged the Dow and Varennes product(s). Most of these substitutes were propylene, like MAP//Pro from BernzOmatic. Some were mixtures with higher hydrocarbons or with other ingredients like acetone. Many of these work acceptably in gas/air torches, but none work as well as MAPP in gas/oxygen torches.

Famous quotes containing the words gas, longer and/or produced:
“Papa died in the gas chamber,
slipping blue as an undressed minnow,
gulping in the shower to wash the Jew off him.”
—Anne Sexton (1928–1974)
“The statue is then beautiful when it begins to be incomprehensible, when it is passing out of criticism, and can no longer be defined by compass and measuring-wand, but demands an active imagination to go with it, and to say what it is in the act of doing.”
—Ralph Waldo Emerson (1803–1882)
“It was not reason that besieged Troy; it was not reason that sent forth the Saracen from the desert to conquer the world; that inspired the crusades; that instituted the monastic orders; it was not reason that produced the Jesuits; above all, it was not reason that created the French Revolution. Man is only great when he acts from the passions; never irresistible but when he appeals to the imagination.”
—Benjamin Disraeli (1804–1881)
