I treat the brass or copper object in diluted selenium acid (1:10 SA/Water) at last twice. Rubbing each time with a soft coth piece till the coating is smooth after required darkening you can also apply a rigid varnish which protects the coating

How do you suggest using the Brass Black, to avoid the brittle patina please? I would like a permanent patina, one that would not be altered during handling of the parts.
Hallo @eldrin83believe I’ll need all the help I can get so all advice gratefully received!
