I made a beautiful entertainment center stained glass door insert with my
dad at Christmas (my first project).  He was so proud of our first
father/daughter project.  I don't have the heart to call and ask him what I
did wrong with the patina.  We used the copper tape and then used lead
solder to hold it together.  I wiped a copper patena over the whole thing
and it looked OK.  It has been on for about two months and now where the
patena turned the lead copper color it is turning black.  How can I fix
this before he comes to visit?  What did I do wrong?  :(

it's nothing you did, basic patinaes tend to turn a dark brown to black
over time (it patinaes). to revive it's copper look, use either
chem-o-pro or a light duty metal polish, or even a light car wax. and
carefull buff up the panel. don't push to hard though or the patina, may
rub off. then, if you don't have the supplies at home, you can spray on
some original spray pledge (yeah the furniture wax), to protect it and
make the rest of the panel shiny.

   Did you use a finishing compound such as Chem-o-pro or auto wax?  If
so, try a reapplication.  If not, try it, it can add years to the plating
effect you are trying to accomplish.  One of the fellows I did my
apprenticship with used to used a laquer to preserve his plating and
patinas.  If you still have problems it could be due to an inadequate
patina application.  There are good and bad ways to do this that include
many points such as clenliness of the piece and the molarity and pH of the
patina.

Happy plating!
