I have got black solder but the lead is still not as black as the solder. Also so I have just experimented with the bits of advise I could find but could find the full recipe heeeelp please.Wendy
AnswerI believe you are using black patina for solder on the lead. It only makes solder black, not lead.
There is black patina for lead, but it doesn't do a very good job. I found that by going over the lead with very fine steel wool, then scrubbing the patina on to the lead with a scrub pad (like the ones on a scotch brite sponge) it does help to make the lead darker.
Stove black polish works well to blacken lead, but it takes a bit of cleaning up afterwards, however it does give the lead a beautiful finish. That's all we ever used in Australia where stove black patina was available. I have not found anything to equal it here. If you order your supplies from an Australian supplier you should be able to get it.
This Place has it. It is listed as black polish paste.
Finally, you can brush the lead with a natural bristle brush. The brush will darken the lead to an acceptable dark finish.
