What elements are in a glass ornament?

A glass ornament typically consists of silica (silicon dioxide), which is the primary component of glass, along with other elements such as sodium (from sodium carbonate) and calcium (from calcium oxide) that help lower the melting point and improve stability. Additional elements may be included for color, such as cobalt for blue, iron for green, or manganese for purple. These elements are melted together to form a molten glass, which is then shaped and cooled to create the final ornament.
