What are elements in pink glass?

Pink glass is often made using gold chloride or selenium as coloring agents, as they can produce a pink hue when added in small amounts during the glassmaking process. Other elements commonly found in pink glass include silica (from sand), soda ash (sodium carbonate), and lime (calcium oxide) as the main components of the glass. Additionally, trace elements from impurities in the raw materials or from the manufacturing process may also contribute to the coloration of pink glass.
