Glenn Posted October 29, 2009 Share Posted October 29, 2009 When soldering, I understand there is a powder that can be mixed to coat the metal. This will keep the solder from wicking past the coating. Anyone know of this product and can explain better how it works, and where to get the stuff?

nuge Posted October 29, 2009 Share Posted October 29, 2009 yellow ochre Most jewelry suppliers carry it, and it works by contaminating your flux. Paints on really easily Quote Link to comment Share on other sites More sharing options...
MattBower Posted October 29, 2009 Share Posted October 29, 2009 (edited) [Edited. Do not use correction fluid unless you have excellent ventilation. It turns out that even the water based stuff produces nasty fumes when burned. My apologies.] As far as I know, these things work by preventing the solder from wetting the underlying metal. Cleanliness is the key to good soldering; these are just reliable ways to make parts of the base metal dirty.

Bentiron1946 Posted October 29, 2009 Share Posted October 29, 2009 I much prefer the yellow ochre to the Wite-Out crap. Let the yellow ochre dry, I use a hair dryer on low to accomplish this. Quote Link to comment Share on other sites More sharing options...
NeatGuy Posted January 10, 2010 Share Posted January 10, 2010 I use a welders soap stone. I works for solder and brazing. Just draw the boundry with the soapstone and solder will not cross. brad Quote Link to comment Share on other sites More sharing options...
