Special Notes:
"Green glass" is a beautiful hue cherished across cultures and eras, and the technique to achieve this color involves mixing specific metal oxides for coloration.

・Iron oxide (Fe₂O₃): Naturally occurring iron content can sometimes cause glass to appear faintly green. Older glass (especially pre-19th century) may be unintentionally green due to iron impurities.
・Chromium oxide (Cr₂O₃):
This is a common coloring agent used to produce a distinct, deep green. It is mainly found in art glass and bottles from the 20th century onwards.
・Copper oxide (CuO / Cu₂O): Produces a slightly bluish green. The shade can range from emerald green to bluish green depending on the copper concentration and reduction/oxidation conditions.

Coloring agents (oxides) are blended with primary raw materials like silica sand, soda ash, and lime, then melted at high temperatures of approximately 1300-1500°C to color the glass. Especially in antique glass, industrial refining was difficult, so naturally occurring metal components often manifested as color, which now contributes to its unique character and individual differences. This glass likely owes its color to naturally occurring iron oxide or copper oxide and appears to be hand-blown or mold-blown glass from the late 19th to early 20th century.
