Electroforming Tutorial for Beginners With Basic Equipment | Part 1
In this video, you are going to learn how to electroform with basic materials.
Electroforming is a very simple process that anybody can do. It's versatile and can be applied to any form of art.
To start, you don't need to know chemistry or electrical engineering.
With a few simple steps you can manage to create beautiful pieces of jewelry or basically any object covered with metal, in this case, copper.
⚠️⚠️⚠️
Some precautions must be taken with the Electroforming solution, it contains irritant substances. You only need to protect your eyes and open wound or fresh scars from splatters. It won't burn your skin, and it's safe if you touch it. Just wash your hands before any other living activity.

Supplies
Here all the supplies you need to start your new hobby:
- Plastic container or glass beaker
- Copper Electroforming Solution
- Adjustable Power Supply
- Connection Cables
- Copper Plumbing Pipe (anode)
- Copper Rod (cathode)
- Copper Wire (0.6mm and 1mm) it must be uncoated
- Cloth pins
- Round Nose Pliers
- Nippers
- CA Glue
- Baking Soda
- Conductive Paint
- Brush (for conductive paint)
- Brush (for the solution)
- The Object to electroform (maple leaves)
Before we start to electroform our objects, we need to prepare them. I decided to make jewelry. A pair of earrings and a pendant.
I'm starting by making 2 jump rings. Using a pair of round nose pliers, I round up the jump rings on the thicker part of the pliers and cut them with nippers. Then, a straight piece of copper with the 1mm copper wire, and two hooks with the 0.6mm copper wire.
I cut the stems of my leaves and replace them with these new parts. The straight piece for the pendant and jumps ring for the earring. I glued all the parts together with CA glue and baking soda. Pouring baking soda on CA glue will make it cure instantly, and it's gonna create a strong bond.
The other 2 pieces are needed as hooks for the earrings.
Gluing hooks directly on a piece will prevent it from floating in the bath. Usually with jump rings and separated hooks they will come up. So you need to secure them by bending them a little.
All the surfaces that we wanna cover with copper needs to be covered with a conductive material. Therefore, we are going to cover them with conductive paint. Conductive paint is gonna “conduct” the electricity in all the non-conductive parts of our objects.
There are lots of different kind of conductive paint out there, water or solvent base with graphite, copper, or silver in it. In my case, I'm using a solvent base with graphite conductive paint that I made my self.
While I'm painting my objects I don't brush the paint on the leaf, I just lay it because I don't to leave strokes that will be replicate by the copper itself.
Graphite conductive paint needs to rest for at least an hour to get activated. If the paint is water base, it also needs longer, since water has longer evaporating time than solvent. So hang your pieces somewhere and wait.
To prepare our electroforming station, we start by filling the container with the copper electroforming solution.
Then we insert the copper plumbing pipe inside and secure it with the red alligator clip of our cable. This is going to be our anode.
On the copper rod, we hang our pieces and connect the black alligator clip on it, and here we have the cathode.
The anode is the pole that will attract electrons and will give back copper ions. The cathode is the pole that will give electrons and attract copper ions on the surface of our pieces.
After I submerged my leaves, I noticed that bubbles formed on the graphite. With a brush, I give it the necessary strokes with the same liquid to break the surface tension and avoid those bubbles to form again.
Different conductive paints act in different ways, so this step may not be necessary.
Secure everything with cloth pins and get ready to start the Power Supply.
But before we operate it, we need to set it up.
With my Power Supply, I usually turn all the Amperes knobs UP and all the Voltage knobs down, and use only the “Fine Voltage” knob. We don't need lots of tension and current, so that's the best way to work. Be aware that some adjustable power supplies may work differently.
Now you can connect the cables and power it.But how many amperes do I need to apply to my pieces?
The right current to apply is in between 0.01A and 0.1A by inches squares. It means that you need to calculate the entire surface of your objects (in inches squares) and multiply it by those numbers.
My leaves measures are 1"x 1"x 2 faces x 3 pieces = 6" = 0.06A/0.6A
For the first run, I go low and slow, so I start with 0.06A.
After 1 hour, I can check the result and see that some copper forms on the graphite.
After 3 hours, I have a little more copper.
After 6 hours, it requires a little more to get completely covered.
After 8 hours I can see that is completely covered, then I go to the next step.
My pieces are covered with a thin layer of copper now, so I need to make it thicker by speeding up the process.
I can raise the amps now to a higher value, but I'm not going to the top. It would be a risk and the objects can get “burned”. I decided to go with 0.4A.
And when I checked them…
After a total of 17 hours, I noticed that on my pieces it grows some copper texture. This happened for 2 reasons, a) the amperes were a little bit higher and, b) I left it for too long at this value. Learn from your mistakes. But maybe is not a mistake. This texture is the peculiarity of this art. Some people like it plain, some like it with character.
I then low the amperes to 0.2 and leave it go for a total of 36 hours.
As you can see from the picture, they are not pretty and also have more roughness on them. But they are electroformed, covered with enough amount of copper to make them sturdy.
They need to be wear as jewels, so in the second part of the tutorial I'm gonna show you how to finish them with advanced supplies. I will teach you how to make them shine with a few different techniques.
