The book gives an overview about electroforming, but does not give basic steps to accomplish this technique. Below is more information from two artists.
In August 2019 I attended The Enamelist Society Conference and took a class from HeeJoo Kim from Korea. To the right is one of her samples - carved in wax, electroformed with copper, and painted with Thompson Acrylic Enamel Paints.
Here is what I learned....
One can electroform a wax form or an organic such as bark from a tree, an acorn, etc. In all cases, after the forming is done, you will need to burn out the original. Thus, if you want to make multiples of the shape, you need to make a re-useable mold and then electroform something made from the mold.
We used a setup with a digital controller from Rio Grande that was developed by Sherri Haab. This setup also allows for electroetching, which is described in full in the book. But a set up for just electroforming is also available (a bit less expensive). We electroformed using copper, but other metals are possible. Below are my basic steps for copper electroforming and enameling. Here is a video of the process.
In class we used the Thompson Acrylic Enamel Paints which was the first time I had used these. They can be mixed to form other colors, just as regular paint. We fired them at 1300°F for about1 minute, but the Thompson site says they fire at 1450°F. We did have a bit of issues with firing in class, so try them both ways.
We brushed them on and also dabbed with a sponge. HeeJoo told us to give do this for about 3 coats. HeeJoo gave us rectangular pieces that she had electroformed from carved wax, to use for painting. I didn't want to use my pieces so I can think about what to do with them. Here are the pieces I painted. The one with the hole was where there was no metallic paint before the electroforming process - I like it as a shadow box to put in a photo or something.
I plan to use grain enamel to enamel my organic forms, but I'll see when I decide what to do with them.
Here isa piece done by Irene Mori - we all thought it looked like an ancient Roman artifact. She's not sure what she'll do with it at this point, but it sure is pretty. This was from a wax carving. Note that the wire to hold it into the electroforming solution is still attached and Irene enameled it (wish I had enameled mine!).
Here is a piece, not yet finished, by Krisztina Vegenas of an organic collage put together by wax and then electroformed.
All in all it was a lot of fun and I was inspired to take this class from having included it in my book. I hope my book inspires you, too, to add to your creativity.
Rachel is a jeweler working in electroforming. She has some instructional information on her site. She seems to work differently than HeeJoo and her talk to The Enamelist Soceity zoom meeting in Sept 2020 was very interesting. The main thing that interested me was electroforming an already enameled piece.
