My guess is not the same source, is there any transparency when looking at the base? However, as I was working on the bibliography revision this week I came across a title that may be where the reference came from.
Newman, Harold (1977), "An Illustrated Dictionary of Glass": 351 pages 608 b/w 17 colour.
Abstract:
2,442 entries. Definitions of wares, materials, processes, forms, decorative styles, principal glass-makers, decorators, designers. From antiquity to the present. With an introductory by Robert J. Charleston - ISBN Number: 0500274517
Not 100% certain but when I worked on that entry the memory of that vase popped into my head... now your post reminded me again... call it intuition.
