I've written about a tutorial on how to color washers with alcohol inks before. The effect is somewhat like water color.  What if you wanted more depth to the design?  Reader Aims pointed me to this tutorial by Tammy Tutterow (no longer available) who shows how to make crackled metal pendants with alcohol inks. The designs do have a distressed look about them.

The beautiful effect is achieved with a combination of Ranger products : alcohol inks, jet black archival ink and Glossy Accents (a dimensional glue) which are available from Michaels and art stores.

Even if you aren't into this kind of metal effect, her tutorial is still worth a look because she has a wonderful way of making a frame for thin copper pendant.

She also tried the coloring technique on aluminum soda cans (shown below) which is a great source of thin metal.

Tammy does not show how she embosses the metal.  She used an embossing die and probably the Sizzix die cutter.   Here is a video tutorial which shows how it is done.
