2 ounce Liver of Sulphur Gel comes in an easy to measure squeeze bottle. Mix with warm water to patina sterling and fine silver metals to a dark brown/black color. Use cold water to patina copper metals. Non-hazardous.
TIP: Bring out the detail in your work after applying a patina by using Pro-Polish pads or a Sunshine Polishing cloth to gently buff the raised points of your work.
