Untitled (Necklace)

Fine gold 999.9 dissolved in acid as chloroauric acid (HAuCl4), blown glass, setting of rhodium-plated silver, 5 x 1.7 cm (diametre), fabric cord

Gold is dissolved in aqua regia, a mixture of hydrochloric acid and nitric acid, until the saturation limit. The name of the acid (ʻaqua regiaʼ) is derived from its ability to dissolve precious metals gold and platinum. Gold produces chloroauric acid. Glass is one of the few materials that is not affected by aqua regia.
