Burnt Finishes, Tips and Tricks
by Brian Calvert
Blow Torch Method
The most commonly performed burnt finish is made using the ordinary gas blow torch. If your going to do this method I would recommend practicing on a piece of scrap basswood to get your technique down since it really doesn't take that much time to get a burn mark. In a pinch and can't find scrap basswood, then try popular which has similar properties and is more common.
Heat Gun Method
If the body you wish to make a burnt stained finish on still has it's original
finish you can achieve a random billowing pattern by using a heat gun made
for removing paint. Just allow the gun to set in one area on high setting
longer than is normally necessary and the paint itself will fly off of the
body like kernels of corn popping out of a hot oil skillet, leaving an unusual
pattern behind. Be careful not to work in one area to long though or you will
be left with pockets of ash in the body which will need to be filled and this
will destroy the continuity of your original look.
A STRONG WORD
OF CAUTION HERE!
The chips of paint that pop off are sticky flying cinders of hot melting
paint, I know I've used this method. Wear plenty of protection including and
not limited to; gloves, safety glasses and long sleeves. Also work in a large
open area where the toxic fumes can escape and the cinders won't hurt anything
where they land!
Heat Gun with Template
If your body is clean and free of all
marks and down to the bare wood it is possible to do a controlled burn using
a heat gun made for paint removal.
A neat trick here is to take a sheet of aluminum foil and fold it over at
least once to use as a heat shield. Then cut a pattern along the edge such
as flames. Start at one end of the body and whisk the heat gun along the edge
of the foil till the pattern starts to form in the wood. Let the body cool
down some and move your foil down a few inches and start all over again, over
lapping the burns in the wood.
