I use the cans of Sterno camp cooking fuel, alcohol based (no soot)...just hold the jig over the flame and count to 5 Mississippi (flip the jig from one side to the other on each number) and dip, have a glass bowl of water on your work table and drop the jig in the water to cool it down (no sticking in foam or cardboard). Works for me for several years now...Your milage may vary.
James 1:22 But be ye doers of the word, and not hearers only, deceiving your own selves. 23 For if any be a hearer of the word, and not a doer, he is like unto a man beholding his natural face in a glass: (KJV)
