Decorating preparation problem

Traditionally, formulations contained silver sulforesinates as the source of silver. These were typically prepared via the reaction of silver nitrate or carbonate with a sulfur balsam such as Venice turpentine to form deep brown materials, as observed for the analogous gold systems [51]. Although these silver sulforesinate systems gave adequate results in terms of decorative effect, problems with shelf-life stability, reproducibility, and the limited solubility range of these materials led to the search for alternative silver precursors.
