vintage jars at a great price

check it. i got these for  50 cents each at the local good will. they are some type of vintage jar, the have seams on each side so theyre molded the smaller ones have ridges on the top and near the bottom say "duraglas" in a script. the big ones dont have much for distinguishable marks, just cAc stamped on the bottoms and some random air bubbles. if you know anything else about this type of jar, im dying to know.  add a little wire and i plan to use these as luminaries on my porch this summer. 

this is a fun shot from our short outdoor excursion to the river this afternoon. i hope X wasnt marking the spot.
