This is yellowish-green or grey lumps that are soluble in water. Barium sulfide is used in brown patinas

The following is a potential recipe:

  • Barium Sulfide: 1 ounce
  • Potassium Sulfide: 1/4 ounce
  • Ammonia: 2 fluid ounces
  • Water: 3 to 5 quarts

The procedure involves mixing these ingredients to create your patina solution. The application of this patina results in an immediate darkening of the metal, creating a matte finish. The final color is best left without a preservative, although this is optional depending on the desired effect.

It's important to note that handling chemicals like barium sulfide requires safety precautions. Always work in a well-ventilated area and use personal protective equipment like gloves and safety goggles.
