I've just read Sue's comment on another thread about early IOW pieces and thought I'd post this.
According to Mark Hill's book the flame pontil mark was being phased out making way for 'flat polished bases and labels from 1978, particulary on Azurene pieces'. Pink Azurene was launched according to the book c 1979. Therefore I think this must be one of the earlier pieces of Pink Azurene based on the facts that it has a flame pontil mark and also the triangular black label. It also has a 'flaw' on the rim, which happened when it was made. The rim is clearly out of shape and has a definite dip in it, and inside the little dip, if you look under a magnifying glass, is a blob of silver. It's not damage done after it left the studio and is not a burst bubble or anything like that. I've been slightly bemused (not that I am criticising at all!) that this piece would still be fully marked and labelled and I guess, sold as a first. But once I looked that up, I presume if it was one of the earliest pink azurenes, perhaps it would have still been a bit experimental and therefore this rim dip would not have been an issue?
