Description
A powdery, blue corrosion product composed of a hydrated sodium copper carbonate. Chalconatronite has been found on corroded bronzes which have been treated with Sodium sesquicarbonate (Horie and Vint, 1982) and on Silver objects that were cleaned or replated using a Sodium cyanide solution (Strahan, 1986).
