This is facinating stuff. I just did a batch of 20 these small bronze statues.
after nickle plating i did them in the brush gold solution. they take about
1 minute. the colour is really deep butter yellow almost coppery and there is this black stuff all over them like patina.
my solution ended up black! my electrodes bubble,well,froth slightly.
is this my high 4.5 volts? i feel the colour is too rich i`m after more of a 9ct look.
