In my experience, the reason for uneven black is uneven finish
before applying the patina. So, do whatever you can to clean that
metal. Suggestions include:
-wire brush on a flex shaft with soapy water
-wet pumice on a toothbrush or bristle brush on a flex shaft
-the metal prep chemical sold by Reactive Metals
FWIW, I feel that Griffith’s Silver Black, which is now a Grobet
product, works better than Black Max.
I didn’t find any on the suggested websites offered by
Orchid members that supplied the silver black liquid I am looking
for. Anyone know what I am trying to locate? Thanks, Joyce
Don’t do silver anymore for years now, but the BEST way to get a
~solid~ black is enamel. Next would be Ceramit or similar, next
would be black antiquing paint… Too black for some tastes…
