Description
This listing is for a embossed round pint milk bottle. It is embossed: EWING'S DAIRY PRODUCTS. It is also embossed fancy E on the back. A Google search shows that this was a dairy in Louisville, KY. in the early 1900's. Couldn't find much more about it. This piece shows sun staining, rubbing , blemishes, iridescent swirls, minor scratches, very minor flea bites, as it should for 100 years old. This is a dug bottle. Purple/Amethyst Glass & the Irradiation Process: The beautiful purple color of this glass is caused by the presence of manganese, which was used in early glass production as a de-colorizer to turn the glass clear. Manganese is one of the oldest glass additives, & purple manganese glass was used since early Egyptian history. Around 1915 most glass companies stopped using manganese, substituting selenium as the clearing agent. Glass that contains manganese will turn amethyst/purple when exposed to ultraviolet rays of the sun or other sources of UV rays. When the process of the sun is accelerated by using UV light exposure, it is called "irradiation". It is a permanent process which reproduces the effects of many years of exposure to natural sunlight, but much faster. A glass item manufactured after this era will not turn purple with UV light exposure, so it is a true indicator of the items age. Thank you for visiting our shop!
