Gail- Although electro forming is a great technique to learn, it is
not really suitable for rings. It's too fragile to hold up against
hand wear. Electro forming is best suited for pendants or sculpture.
It is basically the same technique as bronzing baby shoes. Anything
you can coat with copper powder can be electro formed. Wax, wood,
plastic, whatever. I've even electro formed a petrified lizard. Yup,
a lizard. I've done some pretty whacky things over the last 43 years
in the trade.
The metal deposits though thicker than electro plating are still
Still a fun project to try.
Have fun and make lots of jewelry.
