Another way to enhance the heat of your torch is to build a hydrogen generator and pipe the hydrogen into the flame.

Hydrogen burns pretty good, re the Graf Zepplin, circa 1937.

A sealed glass container of water with two plates therein, an anode and a cathode, with leads coming out to a DC source of up to 50v, increase the voltage untill you see the water bubble, and the bubbles are hydrogen, which can be taken off by a line affixed into the glass jug.

Or, you could go to a welding supply house and buy a bottle of hydrogen, but it is some pricey stuff, but it is about the hottest burning gas around, I think -- I believe it is used in some plasma cutters.

At any rate, a little of it will enhance your torch to where you will not have a bit of trouble brazing or silvering.

Speaking of silvering, old coin silver works good, and is good value for the money, like an old, non-collectable silver dime can be had for a couple of bucks, and sliced up with some snips will provide a LOT of silver for silvering at low cost.
