I agree that the first 15 are Veiligglas - some nice ones in there too. Number 16 looks like a German striped transparent type. Number 17 looks European - a compressed sparkler type? And if number 18 is not a Peltier Rainbo it sure is an amazing replica.
I do think Art Fisher was a sort of glass magician. It's amazing how he would use just a tiny bit of colored glass under a white patch with a clear base and make the marble look like it had a colored transparent base.
