Somewhere, I have a pint, amber, "fruit jar" from the 1930s or so but doubt it was an Atlas. I do remember it was used in a medical mode to store clean bandages, etc. Maybe put out by J + J in connection with the Red Cross.
Two questions. How does one irradiate the pictured jar with the bail still intact? Secondly, is it possible to get colors other than purple?? (Be gentle, old guy here. ) Thx.
Pretty sure this one is irradiated. Manganese used to be added, which would eventually turn pinkish to purple depending on the amount. Selenium was then used and would usually turn a "motor oil" amber when irradiated. There may have been other additives after that.
