Hard Boiled Eggs Method To Apply Patina on Copper/Silver/Brass
Although impractical, this Hard Boiled Eggs method can avoid your precious creation get ruined by Liver of Sulfur. Liver of Sulfur is a sulfur solution that’s widely available and used to give rich patina on silver, copper, and brass. However, softer stones may be stained by this patina solution if you left it in the solution. Liver of Sulfur may leave undesirable effect on your stone. Applying Liver of Sulfur should be avoided on soft stones such as non-stabilized Turquoise and light colored drusies (I’ve had some stain on my drusy caused by LOS).
How to Patina Silver/Copper/Brass using Hard Boiled Egg Method.
Materials:
- Chicken egg
- Zip lock bag/small plastic container with air tight lid
- Small towel
Instruction:
1. Hard boil an egg. If you stored your eggs in the fridge, boil for at least 15-20 minutes.
2. Immediately put the hard boiled egg inside a zip lock back along with your jewelry to be patina’d. If you use plastic container, slice/crush the egg in 4 parts and put each of them in each corner and your jewelry in the middle. I like to put my jewelry on top of the egg so there’s no “flat” spot left unoxidized. Quickly put the lid on.


3. Wrap the container inside a towel. This will keep the eggs warm longer. The oxidizing process will stop once the eggs has cooled down.This process usually take 20 minutes - an hour. If you have a lunch box that can retain heat, you may put the container inside that to prolong the heat.

4. Once the egg has cooled down, remove your jewelry. If the patina is uneven, you may repeat the process with a new egg.
Your jewelry should look like this if the patina process is successful. Evenly dark all around.
