Patina for silver and metal clay 12g

A liver of sulphur solution used to blacken metals, especially silver. It gives them the look of an antique metal, less bright and shiny. The degree of darkening is controlled by the length of the bath and subsequent brushing. Mix the red liquid with warm water (two to three drops per 1dl) and immerse the piece of jewellery. Move it gently and take it out once it feels dark enough. On contact with air, liver of sulphur releases hydrogen sulphide and smells of rotten eggs. Rinse the patinated item well in soapy water to stop the patination process. Store the solution well sealed in its bottle, away from light. It will then keep for several months. It's advisable to wear gloves while patinating, to protect your hands from staining and the unpleasant smell. Once you start working with the patina, you'll notice it changes colour gradually. It moves from antique gold, through purple and violet, to deep blue. You can take the item out at any point to make use of this remarkable colouring, which, although it won't last forever, will certainly last a few months.
