E.O. Brody Glass Vase

Here is something I know nothing about....milk glass. First of all, is this milk glass? All I know about this, is that when I was a child my grandmother had this all over the place. She used to keep candy in it. So, if anything, at least it reminds of those horrible Christmas mints I used to eat as a child (the green ones). And of course, much better than that, grandma and grandpa. This is labeled on the bottom:

"EO BRODY CO
MJ-42
CLEVELAND OHIO USA"

I am not even sure this is glass...looks like plastic until touched.
