Yes, alcohol leaves soot, while butane does not. But butane certainly will 
burn the shank just as quickly as any flame.

While everyone is experimenting with burning in shanks, maybe some of you 
could try something I figured out while spacing and getting the twist out 
of very old, brittle (brown) upright shanks. Butt plates, so only burning 
would space them.

I was using heated bending pliers, and the shanks were grabbing every 
opportunity to shatter. Then I put a few drops of vodka on a disposable 
foam brush, and swabbed the shank with it, all sides. Only a few drops 
because any more just ran down the shank and ruined the butt leather. As 
soon as the pliers touched the shank, I heard a light hiss, and it would 
get soft as butter. It bent so easily that I bent some too far and had to 
bend them back again. Then I got them bent too far back, swabbed them 
again, and bent more gently, till they were just where I wanted. Let them 
just sit there overnight, getting dry and cool. They were spaced the same 
next morning. (i.e. they didn't seem to have any stored twist waiting to 
rebound.)

I've never tried vodka on grand shanks, but as long as you're testing old 
scrap hammers and shanks, why not give it a go?

And the vodka doesn't affect the foam brush, which can be used over and over.

Best,
sssssssssnnn (hiss of vodka turned to steam. showed no signs of combustion. 
I imagine that the alcohol evaporates almost instantly.)
