Just thought that you might know offhand about MAPP (I spelled it wrong...shows how much I know about it!) gas.

I looked up a table on a site about welding and the temps are as follows:

Acetylene: 3160C Propane: 2810C MAPP: 2927C

Don't know if that qualifies MAPP as useful...all I know is that it's more of a hardware store stock item around here as opposed to Acetylene.
