Topic: Gray-Stan 1930s mottled vase.

  Hi Nigel,
  I’ve just had a look at the pull-ups and yes they also have black bits.

   I’m going to try and get some close-ups—not sure whether my camera is up to it though, so don’t hold your
    breath 

     Many thanks

IMHO, if it's like that going along each of the pull-ups then it is meant to be there since it looks purposeful to me. The black speckles and collection of black around some of the bubbles within the same area looks like its supposed to be there since it doesn't have a random look.

If it was just like that only in one small area that might be different.

Although having said that I am conscious that I have seen similar random effects on Nazeing glass, particularly from the 1930's, that has half-hearted attempts at creating a different effect where it does not come off, but seen enough that you realise they were trying something out - but I digress as that's not Gray-Stan!

    Hi Nigel,
    The black specks and the residues around some of the bubbles could certainly have been deliberately
     introduced into the mix. Probably were.
    If so, to me at any rate, it seems to have worked—very difficult to pin down why though.
    Of course it could be an example of “ the whole is greater than the sum of its parts “ 

     Many thanks for your help
