Plumbers Smudge Paint

[martin spisak]

Im wondering if you can help me, Im looking for a supplier of smudge paint (plumbers black) or a recipe so that I can make it.It used to be used to mask off the areas where solder was not wanted during lead wiping.I used to use smudge paint many years ago when lead joints and sweating brass flanges into copper tanks, and I now want to use it in my work constructing research equipment here in the University of WA, but I am no longer able to find a supplier.I have tried Yellow Ochre which is used by jewellers but it is not suitable.I would be most grateful for any assistance you can give me in this matter.Regards George.

: :Plumbers soil, used in making wiped joints, is a composition of glue, lampblack and water with a consistency of a thin paste. It is applied with a paint brush to the ends of the pipes to be joined. If black rubs off, there is too much lampblack. If the soil cracks and falls off when the pipe is bent, there is too much glue. : : supplier of smudge paint (plumbers black) or a recipe : : so that I can make it. : : It used to be used to mask off the areas where solder : : was not wanted during lead wiping. : : I used to use smudge paint many years ago when lead joints : : and sweating brass flanges into copper tanks, and I now : : want to use it in my work constructing research equipment : : here in the University of WA, but I am no longer able to : : find a supplier. : : I have tried Yellow Ochre which is used by jewellers but : : it is not suitable. : : I would be most grateful for any assistance you can give : : me in this matter. : : Regards : : George.
