Hi Ben,
Although most Whitefriars textured vases were finished with a polished out pontil mark, on the odd occasion some of the glass blowers made glass pieces for themselves, or for friends and family.
Some of these would have left the workshop through the back-door and there have been several examples found over the years with a snapped off unfinished pontil mark to base.
Of course some of the various textured range patterns were also finished smooth to the base with no pontil mark at all.
Then of course there are also the horrible fakes which usually have a moulded fake pontil mark.
Can you tell me what pattern or design shape the vase is?
Best wishes, Michelle.
