M the examples I posted are just what we consider crackle & the other European examples posted are something we simply don't often see over here, e.g. the wider channels created by further manipulation of the piece. The vast majority (probably 95%+) of U.S. crackle are the tight line type & even most of our (U.S.) turn of the century hand glass houses didn't seem to be very involved in crackle or at least not nearly as much as European manufacturers. Mount Washington, Sandwich, Hobbs Bruckunier, made some crackle during the late 1800's into the turn of the century & later Steuben, Fry, Cambridge, Tiffin made limited crackle, but I don't believe anywhere to the extent of your Europeasn manufacturers & (again) its the tight crackle. Of course probably the kings of crackle over here were Blenko & Pilgrim as they both were quite prolific in this regard, far more so than anyone else & they were primarily of a later period. Maybe it was a marketing (sales)problem over here early & it simply did not catch on, I don't know, but its always (for me anyway) interesting to see the variables involved between U.S. glass & European glass techniques during concurrent periods.
