This is an older jar in perfect condition. I found this and two other ones in different sizes in an old barn with other things. The jars appear to be either an Azure Blue or Colonial Blue. I'm not sure what the notable differences are between these two shades. Nor am I certain that I'm calling the color correctly. Any ideas on who the maker is or what color this would be considered? I'm assuming it's probably Fenton or Westmoreland but I can't confirm this. Thanks for your help.
