I am close to Peoria and could use some mentoring. After picking up some clays these past years I started looking at glass. My brother-in-law bought me a jar full at a garage sale as a joke because he thought I had loast all of mine. In that jar was what I believe to be my one and only Popeye corkscrew and I was hooked, a nice purple, yellow, white, mint, but not wet. My initial purchases have been at local auctions. Did not pay much, but didn't get much, either. My interest is machine-made. I have learned what Vacors and cat eyes look like, but even some of those are nice. I have looked at a number of books. Any recommendations? Thanks for any help.
