Rare ORNATE miniature ANTIQUE purple EAPG Early American Pattern Glass tiny CUP

Tall beautiful AND fancy, deep SUN COLORED AMETHYST (SCA) antique CUP or GLASS. This is NOT a reproduction but an ORIGINAL ANTIQUE B lown I nto M old glass, dating back to the 1800’s. Che ck out the design, pattern, that it was molded in = Early American Pattern Glass. And also the astrological / sunburst pattern on the base. Condition : It is in SPARKLING CLEAN condition. It may have some wear from use and/or age but it looks to be in just about perfection condition. NO cracks, chips, dings, damage, etc. Age : An ORIGINAL ANTIQUE blown-glass vessel, ca. This little vessel has all of the similarities and patterns of a normal size cup except this one comes in an extremely miniature size, being just over one inch tall. It possibly was part of an antique doll tea set but the detail and work that went into it seems like it was designed for a much more sophisticated use, like for sipping fine liqueur out of. This purple color is the result of having manganese in the glass. Manganese is a mineral, a rock, that was mined, crushed, and pulverized into a powder, then added to vats of molten liquid glass, and acted as a decolorizing agent to turn the natural aqua-tinted glass into a pure crystal clear colorless glass. Then it was blown into a mold to create a vessel. But when exposed to the ultraviolet rays of the sun or other sources of UV rays, it triggers a chemical reaction and the manganese starts to oxidize and slowly turns a lavender or amethyst color. The end result is what collectors refer to as SCA (Sun Colored Amethyst) glass. The longer it is in the sun the purpler it becomes. This little shot glass was exposed to some concentrated UV rays which had the same affect as the sun, but a lot faster. It has not been colored, stained, or altered. No matter how a glass item has turned purple (direct sunlight or UV rays in controlled environment) they all turn the same purple color as it is the same chemical reaction taking place. The only difference is the time it took to turn purple. What is important is that an item is old enough to turn purple as with few exceptions, only clear glass from before 1915 have manganese in them and will turn SCA. After this, with the start of WWI, manganese was no longer available as foreign imports decreased and domestic resources turned towards the war effort. Selenium sulphate then replaced manganese as a glass de-colorizer and when exposed to UV rays, it turns a yellow / straw color, and a dark burnt amber color. Generally speaking NO MORE purple glass after 1915! Not only does this deep purple/amethyst color make this a great looking little antique glass, but it also authenticates it as being truly antique. In summary, look at the design, thick, heavy-glass, and just beautiful in the deep lavender color, check it out!
