    Hi All

    So my wife does vintage fairs, and she specialises in coloured pressed glass. She recently purchased a 'Job Lot' as there were a few things in there she wanted, but in amongst that was this ribbed, fluted iridescent vase.
    What I would like to know is about the base. I was always under the impression that a broken pontil was an indication of age, as beyond a certain year they were ground down. However this vase has not only a broken pontil, but above it there is a plastic sticker, which clearly puts my theory down the toilet.

    Can anyone clarify about broken pontils on glass, and when this was phased out? Or do some makers still do this?

    Any info would be great, as I just don't know the answer.

    Thanks as always.
    Hamish

      Snapped pontils are still common.

      Ah OK. My thought was that with today's health and safety, having a sharp piece of glass at the base of a vase would limit it's saleability.

      Not to be taken as a sign of age as there is plenty of old glass with the pontil mark polished out & plenty of new glass with rough pontils.
      Basically what it tends to indicate is that an item has been hand finished, eg there was a need to attach it to a pontil to continue working on it.
      This vase would have been attached to a pontil rod to create the crimped top rim, which is usually done using a foot pedal operated tool.
      From what I can see the label reads KIG, which could mean it is a product of the Indonesian manufacturer Kedaung Industrial Group, founded in 1969.

      Well hats off to you, great info. And that explains the pontil mark. Every day is a school day.

      Thank you.
