Instructions for Use
Cool Tools Patina Gel can be made as strong or as weak as you prefer it. A lemon yellow color is a good starting point. Use more or less to adjust the strength. Antique Patina
: Stir 1/4 teaspoon of Cool Tool Patina Gel into a glass or plastic container with 6 to 12 ounces of very hot (not boiling) water. Dip the articles into the patina solution using tweezers, or suspend from a bent wire, or use gloves. Once you have the color you desire, remove the articles and soak in a neutralizing solution of water with some baking soda added to it for about 5 minutes, then rinse, dry and finish.
: Mix as above, but use lukewarm water instead of hot water. Dip the items quickly in the solution and remove. Watch as the colors develop. When you see the colors you like, immediately immerse the articles in the neutralizing bath to stop the progression.
Rainbow Patina on Steroids
: Follow the instructions for the Rainbow Patina above, but add about 1 tablespoon of ammonia to the solution. The ammonia brightens the colors and makes them pop. Neutralize the pieces after you achieve the colors you like.
Frequently Asked Questions about Liver of Sulfur Patina
- Warm the metal object you intend to patina prior to dipping it in the solution. This will insure that you get an even patina on the metal.
- The metal must be completely clean and free of finger oils, polishing compound, grease, etc. Use a solution of warm soapy water with a little splash of ammonia to clean the metal. Use a toothbrush to get into nooks and crannies. Rinse and pat dry with paper towels, then patina.
- After dipping, try using a paste of water and baking soda to clean away the oxidation from the high spots. In fact, keep a box of baking soda at the sink when working. Pour a tablespoon or so of baking soda into the palm of one hand. Add a few drops of water and make a thick paste. Use your thumbs to rub the metal with the paste. This will not only remove the oxidation from the high spots, it will also help neutralize the oxidizing action. The object can be left as is or polished as desired.
- For the darkest black, dipping the object several times is better than one long soak. Leave the object in the solution until it turns dark gray. Remove and rub away the unwanted oxidation with a baking soda paste. Rinse, then patina again. Repeat until you are happy with the black color.
- It's very important to neutralize the freshly dipped pieces. If you do not neutralize the metal, the liver of sulfur will continue to react with the metal and your item will require an immediate re-polishing. Leave articles in the neutralizing bath for about 1 or 2 minutes for ordinary metals, and a little longer for metal clay. Metal clay is porous and the patina solution can soak in and continue reacting for several
Q: Isn't liver of sulfur dangerous? I've read the MSDS and it says it makes toxic gas.
A: Sulphur dioxide (SO2) gas is created when sulphur is burned. When used as directed, liver of sulphur does not pose a sulphur dioxide health hazard because we do not burn the material. We mix it into solution. We avoid using temperatures higher than boiling because some amount of sulphur dioxide gas can be released at temperatures higher than boiling.
Q. Isn't the stinky rotten-egg smell poisonous?
A. The rotten-egg smell is hydrogen sulfide gas. Minute amounts of hydrogen sulfide gas are released when liver of sulphur is mixed into water, but these are tiny amounts. Our noses can detect a very small amount of the hydrogen sulfide gas; we can sniff out only .5 parts per billion. Where it becomes dangerous is when the concentrations are high. At a concentration of 100 parts per million (compare that to .5 per billion), the gas is dangerous...it can kill you. However, at dangerous levels the human nose is actually unable to smell it. That's because at toxic levels hydrogen sulfide gas destroys the ability of the olfactory nerve to detect it. So, if it stinks, you're okay. Still not convinced? Did you know that hydrogen sulfide gas is what makes the smell when people pass gas? and that it's flammable? It helps put the risks in perspective.
Q. Do I need to wear gloves when using liver of sulphur? Isn't it dangerous to touch?
A. Some people recommend gloves at all times. Gloves are optional. Try to keep the solution off of your fingers. Wear gloves to be sure. I usually don't wear gloves. Not because I have a disregard for safety, but because I'm not bathing in it. If a little contacts my skin, it's no big deal. I wash it off. Sulphur Facts:
Sulphur occurs naturally in volcanically active hot springs. People have soaked in hot springs for the health benefits for millenia. A 2% solution of sulphur is used to treat mange in animals (Lym-Dip is a popular product for this).
