[N2TK]

Isn't MAPP hotter than propane? Can't you braze with MAPP whereas propane
doesn't get hot enough?

Prestolyte is acetylene..made by combining water and calcium carbide.
Used by welders and plumbers..  Mapp is a petroeum dirivative as is
propane..  Can't get a flame as hot as with acetylene...

Y'all be careful, hear..
