Bowl, Antique, Vintage, Kiriko, Showa, Taisho, Lead Glass This is an antique and vintage bowl of cut glass, kiriko work, made of blue opal glass. It features cut glass details on blue colored glass. It is pressed glass from the Taisho and early Showa periods. "Colored glass" is a two-layer structure with a thin layer of colored glass over transparent glass, creating a contrast of colors through the cuts. Opal glass is a type of glass that appears milky white or colored and translucent depending on how the light hits it. It emits a fluorescent color when exposed to a black light, and is believed to be uranium glass. I have enjoyed it as interior decoration. Overall, I think it is in good condition, but please refrain from purchasing if you are concerned, as it is a used item. Approximate size is as follows: Diameter: Approximately 20.5cm, Height: Approximately 8.5cm # Crystal Glass #Uranium Glass #Opalscent #Showa, Taisho Retro #Antique #Vintage #Kiriko
