Terry and Martin's vase within your blog shows a aqua vase that I have to say, looks the same colour as my bowl. The picture you have just posted does not look the same colour, more greener I would say. This is not to disagree with you either. like you have said, it could depend on the camera shot. I am being slowly convinced that it could be green cased every time I look at it now and like you have also mentioned and ref. to catalogued details, that if cased it does not fall into the same catogary as FLC and of course, it is not a 6". With this in mind, I will label this bowl as a cased green, that was made between the period of 1964 and 1966. Thanking you ever so much for your help. Appreciated!
