Tall HALF GALLON deep PURPLE colored antique Fruit Jar. This is NOT a reproduction but an ORIGINAL, 100 year old genuine antique canning jar that was hand B lown I nto M old jar (BIM) with a ground top, dating it all the way back to the 1800’s. TRADE MARK / FULL MEASURE / AGS (monogram) / 1/2 GALLON. The AGS monogram stands for A. Base of jar embossed. / PATENTED / APRIL 7 1896 / DECEMBER 1 1896 / BOSTON & NEW YORK. The April 7th date applies to the ROYAL JAR that they made, with the glass lid and wire bale, the forerunner to this jar and the latter December 1 date pertains to this screw threaded jar. Condition : Jar is in NICE CLEAN condition. It has inner content residue and outside wear, in the form of light scratching, scuffs, scrapes, though nothing significant. It also has a very shallow open bubble next to the monogram, a manufacturing defect. It has NO cracks, chips, dings, damage, etc. The ground top of the jar has the usual flaking/chipping/roughness, typical from the manufacturing process. The zinc lid with milk glass insert has heavy wear on it as well. Age : An original hand-blown jar (Blown-In-Mold = BIM) with a ground-top, ca. A super JUMBO SIZED nice clean jar, and a SQUARE one at that, something that is not often seen. It is an early one too, not only on account of the 1896 patent date but also on account of it being a hand blown into mold ground top version. Then there is the magnificent DEEP PURPLE color. You hear about old glass turning purple in the sunlight… The 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 bottle, jar, or other object. 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 bottle was passed through some concentrated UV rays. Which has the same affect as the sun, but a lot faster. It has not been colored, stained, or altered. No matter how a bottle or jar 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 a bottle or jar has to be old enough to turn purple as with few exceptions, only clear glass from before 1915 has manganese in it and will turn SCA. Then, with the beginning of WWI, manganese was no longer available as foreign imports deceased 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.
