A gaggle of paperweights

Only the two paperweights in the center of the first image are marked. The white one is marked BZ for Bart Zimmerman. The monster purple one is marked "Maude and Bob St. Clair 1982" by St. Clair Glass Company. That is the largest lump of glass purposely made as a paperweight that I own. It is cumbersome to handle. The pink one has a nicely hot finished bottom, but no maker's marks. The other three have very rough bottoms which are ground flat. No idea who made those. These six caught my eye among many paperweights that I have seen in the wild.
