Midas Liver of Sulfur - 1 Qt. One of the most effective oxidizers for silver, copper and bronze, liver of sulfur works best when either it (or the workpiece) is hot, producing a durable black finish that will not fade, flake or peel off.
Please Note:
Liver of sulfur, once opened, has a limited shelf life. Keeping the container tightly sealed when not in use will help lengthen the shelf life (up to six months). If you find that you aren't using it within this time period, you may prefer either the gel or dry concentrate products, which allow you to mix only what you need as you need it.
