![]() ![]() The Chemistry of Glass is at the core of this controversy, and the history of North American glassmaking is subdivided by the price of lead and the US Civil War. Don’t give this guy a hard time though as I don't believe he's the source of these irradiated fruit sealer jars. Dumpdiggers found this on after doing a Google search on the words ‘irradiated glass bottle’. Here's a Ball fruit sealer jar that's a weird color of amber. Dumpdiggers is of the opinion that Digger Dave is ruining the historic glass he finds, while fostering deception. He should probably stop this practice altogether. Here is a Digger on eBay selling irradiated glass which he admits is altered (but not in the headline, and only after suggesting that it could be the product of the sun's own ultraviolet light) and his page contains some information about the history of manganese in glass making. A rare or unusual color today probably means that somebody somewhere tampered with the chemical composition of the glass (using gamma radiation) to make it a unique specimen, and now unfortunately that piece is ruined forever. It isn't natural because no druggists bottles, cough medicines, hair tonics, lotions, whiskeys or sodas were ever made that color amethyst, or in those particular shades of cobalt blue, or those unnatural shades of amber. Radiation of old glass produces colors without historical precedent. Thankfully, experts like Dwayn Anthony at the National Insulator Association have created a comprehensive collection of fakes to help warn amateur enthusiasts over the past six years they've conducted extensive research and subjected many different makes and models of insulators to different types of radiation to photograph and catalog the results. Even though some sellers do admit their insulators have been ‘altered’, the foremost objective of their fakery is immediate profit with no regard for the effects on the insulator collecting hobby. That’s because there are so many irradiated insulators on eBay and some are gorgeous and exhibit previously unknown colors. Irradiated glass is a problem for bottle collectors and a nightmare for insulator collectors. Sometimes called desert glass, or sun-colored amethyst glass, these pretty purple bottles are fake their color is artificially produced by gamma radiation in a lead lined chamber by an unscrupulous merchant with one motive – profit. ![]()
