I am making a silver ring that is completely oxidized black. Is
there some process to coat the oxidization so that it does not wear
away over time. Right now I am using win-ox or liver of sulfur which
do a great job oxidizing but I would like to protect it somehow. I
see designers in large department stores who have oxidized pieces and
it always looks slightly different. I have a feeling they are either
using a different process or use some sort of coating. I tried clear
nail polish but it make the pieces shiny which I would like to avoid.
Any help would be greatly appreciated.
