Larry Mong's Method of Copper Oxide Finishing
I visited with Larry Mong. He's the King Of Copper Oxide (aka Copper Japan).
It's a dark background with bright copper streaks running through it.
He asked we share his method for achieving this finish. - Steve Cunningham
- Heavy copper plate the piece, and buff to a shine.
- Take clear lacquer, on a brush, and clear coat where you want your streaks. Larry uses a pinstripe brush.
- Mix 1 part Liver Of Sulfur, to 8 parts of water. Heat the mixture to 105 degrees Fahrenheit.
- Dip the parts in the mixture. The parts will turn dark very fast. When the parts are as black as you want, pull them out. Rinse with clear water.
- Hand polish the parts. Do not buff with a wheel, as it's too fast, and you'll buff through the darkened areas.
- Clear coat your parts.
