Which is specifically why I mentioned rosin. Though any acid could likely be used so citric acid or something that could work as well.
- jaclaz 4y agoYep, but I don't think that just acid is good enough. Choridric acid + Zinc was traditionally used in tin (but lead isn't so much different) soldering/brazing, particularly of copper and brass because the Zinc had some role in the chemical reaction, AFAIK.
