To test the shelf life of Cool Tools Patina Gel, a sample container was left out, uncovered, for over a year. Over that time a thin skin formed on the surface. After 14 months, the skin was stirred into the gel, and a batch of patina solution was mixed. The Patina Gel performed identical to another batch made from fresh Patina Gel.
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) distilled water. Dip the articles into the patina solution using tweezers or use gloves. Once you have the color you desire, remove the articles and soak in a neutralizing solution of water mixed with about 1 teaspoon of baking soda for about 5 minutes, then rinse, dry and finish.
Note: Well water and municipal water can have several different types of elements that can affect liver of sulfur. To avoid this, use distilled water.
