When we found this water bottle, we automatically assumed it much be an unusual example of a Blenko #384, but it's been pointed out to us that it's actually something more unusual: it's a rare example of a non-production water bottle made by Bryce Brothers.
Bryce was located in Mt Pleasant, Pennsylvania, and from the 1920s until they were bought out by Lenox in 1966, they produced extremely high-quality hand-blown crystal stemware and tableware. We're personally very fond of their MCM designs from the 1950s and 1960s, which were marked -as so much Bryce was- by intense colors and unique optic patterns.
Aside from the optic pattern, the other feature which marks these bottles as not Blenko are the markedly sloped shoulders. According to one of the leading experts on Blenko water bottles, a gaffer who worked at Bryce said these were not a production item, but made by the workers as gifts for friends and family. It wouldn't surprise me that someone at Blenko had produced a wooden mold of the sort Blenko, as it would be cheap and easy to do. Allowing glassblowers to produce one-offs and whimseys during their lunch hour was a time-honored tradition of glass works, going back at least a couple hundred years.
The color of this example is "Cerulean Blue" which was Bryce's name for their intense, light transparent blue. The optic is a diamond pattern, which would have been generated by a separate optic mold (which is the reason these bottles turn up with several different optic patterns).
Size: 8" tall by 6,25" wide by 2.75" deep.
Condition: a bit of wear at the corners of the bottom, otherwise fine.
