Copper Embossing Today

Techniques and Materials for Copper Embossing Have Changed Over the Years

Looking for information on copper shim. I used to make copper wall pictures years ago but have forgotten what to rub over the finished picture etc.

Any info would be much appreciated.

I'm confused by your terminology. A copper shim is a small piece of copper used primarily in electronics to separate/protect components.

However it sounds like you're taking about copper embossing. I used to make copper plaques as well.

Take a thin sheet of copper. Place it over a debossed mold. Use wooden or metal embossing tools to transfer the design to the copper.

Treat the copper with a sulphur compound to discolor and cure the copper finish.

Polish.

Remove the copper sheet from the "mold".

Frame.

Use in collage, fuse to glass or use to cover wooden/papier mache boxes or picture frames among other things.

Is this what you have in mind? As I mentioned, we used to use a smelly sulphur solution to give the copper a burnished look. Today artists use India ink and other less noxious finish materials to enhance the relief effect or even color the raised elements.

As well, a Metal Backing Paste is often used to fill and protect the embossed areas.
