This is a vintage sandwich glass bottle. It is a flattened rectangular form. The light brown glass is suffused with dark brown spots among various shades of light brown and grey. The base is flat and shows the swirls of the glass. The opening is matched with an agate cap. This process of making this bottle is probably very similar to the methods established by the Imperial Glass Works, but this is a later production during the Republic Period of China during the 1920's and 1930's.
Similar glass snuff bottles are often mistaken for agate bottles. In truth it may be just as easy to carve an agate bottle because these bottles were very difficult to make.
