Color can create new business for glass
Glass is a transparent and solid material with many useful properties, and widely used for buildings, trains, buses, fluorescent lights, home appliances, smart phones as an essential part in our lifestyle.
In The Shosoin Repository of the Todaiji temple in Nara, there is a blue glass goblet with a metal stem that was manufactured in Nara period (the eighth century). It is said that the precious treasure was brought from the ancient Persia.
From remote antiquity, glass has been highly valued because of the beauty appearance and an art of luxuriousness; consequently, glass has been freely designed and processed into various shapes, size and colors.
OKUNO is the one and only manufacturer in Japan that provides glass enamels for glass decoration (product name, GLASS COLOR).
