Hi jp, thanks for that. I have just googled and found an interesting article (Cambridge Glass Fair) that gives a potted history. Seems that 1892 was a relevant date, when James Hartley`s grandson restarted the firm. The only odd thing is that the firm finally disappeared in 1989, 3 years before the centenary marked on the base of this ?? I must say though that the colours of these vases is startlingly beautiful. I must find out more. Many thanks for your help thus far, (and for alerting me to this wonderful glass). Jeff
