Vasart/Strathearn thistles
http://www.ysartglass.com/Vascat/VasV001.htm V009, and others.
Monart did some thistle based designs.
Edinburgh Crystal did everything, Decanters, Glasses, Jugs, Vases and tumblers in thistle shapes. There is also a mass of other pressed glass in the shape of a thistle which is a Scottish emblem. No doubt there are collectors who collect just for the shape.
We talk about any glass from fibre-glass tthrogh glass bricks and jam jars to finely carved glass sculpture - nothing in glass is sacred (Excepting religious glassware of course).
