Matt, I think the early aqua stuff that turns is from naturally occuring manganese.I have found several glasshouses in which stuff turns at a higher percentage.The flask shown was blown in Zanesville and alot of their stuff turns or glows.Alot of 1858 jars in aqua will turn as will some cone inks.I have purple umbrella inks,a squat soda,cathedral peppersauce,and other traditional aqua bottles.Alot of the hutches turn from aqua to other colors.Aqua insulators are known to and do turn cobalts,olive greens,yellows,I have had a couple bottles turn light shades of blue but not cobalt.Heat will not effect the purple color,but will quickly change the ambers back,sometimes revealing a purple color underneath.Greens and browns are not permenant and if you produce one,selling it is dirty.It will change back to the original color.Doug
