I'm not going to be of much help really Keith......other than to say the colour looks about right, although I'm less certain about the bubble structure - fairly certain the bubbles are wrong for Gray Stan, which normally appear without a dark halo  -  whereas Nazeing pieces usually do have the halo.          However, I don't see any examples in Geoff. Timberlake's book with exactly that bulbous profile at the bottom of the vase.
The alternative would be S. & W., possibly, and with the wear you mention, I'd suggest possibly pre 1940 :)
What does Bernard think?

Thanks Paul,it is similar in shape to some S&W pieces,see picture,maybe Bernard will pop in ;D ;D

Keith & Paul — it has to be RB(S&W).   It could have been made the same day as the example I had through my hands.   Specifically:
  • Much too heavyweight for Nazeing,
  • Finer granule size of the mixed colour and bubble producing agent,
  • Very high quality luxury pontil finish — reasonably standard on RB(S&W) but unusual on Nazeing.
    • Lovely vase.

    Please be cautious about assuming either Nazeing or RB(S&W).   As far as I know the technique wasn't patented or registered, and it is reasonably obvious how it was achieved, so anyone could have used it.   Only recently I found out that Benny Motzfeldt used the technique postwar at both Randsfjord and Plus.

    Fascinating comment, Bernard - but you have really piqued my curiosity.

    you say:

    "As far as I know the technique wasn't patented or registered, and it is reasonably obvious how it was achieved, so anyone could have used it."

    I'm afraid I have puzzled and puzzled over how this bubble technique was produced for years. The "reasonably obvious" has eluded me!

    Please, please would you be kind enough to explain it to me and put me out of my misery?

    Also, I'm curious about your comment on Benny Motzfeldt employing the technique.
    I have the '84 book and can see no piece in the photographs - and I have 16 various Benny pieces, not one employs it.
    What have I missed seeing?

    Sue — Just so that you can smile again, here goes ............

    See topic Marie's bubbly blue cased in green square vase (http://www.glassmessages.com/index.php/topic,47120.0.html).   You can see the concentrated colour around the bubbles, same as Nazeing and RB(S&W) cloudy.

    Obviously the effect varies with the proportions of the bubble producing agent and the colouring agent, and also with the granule sizes, and other factors such as rate of cooling.   But I see it as the two agents mixed together as granules or a powder and the gather picking it up off the marver by being rolled in it.

    When the next casing layer was applied the two agents would perform, producing bubbles and liquid colour.   A combination of surface tension and other forces would pull the liquid into the triangular gap around each bubble between the two casing layers.

    Try it for yourself.   Put a little diluted coloured washing up liquid in a self-seal bag with a little air.   Seal it, shake it up, and leave it flat on your kitchen worktop to see what happens.

    -----------------   Interlude while I do it again   -----------------

    See the way the colour drifts towards the edge of the bubbles, outlining them?

    Bernard - I have one of those,  ;D (having tracked it down eventually, then got lost getting back here). I have 2 inkpots and 2 globes of different sizes in this exact design. They really do not have these Nazeing-style bubbles. There is no outline of concentrated enamel around the bubbles. If I look through the base towards the light, I can see some bubbles have a "concentrated" clear outline.
    I'm as confused as ever.
    I can see this style of bubble in Nazeing, in Grey-Stan, I've seen it in Ysart glass, I see it in that as yet unknown maker of stuff like this which is generally labelled "Scottish Glass". I really do not see it in any bit of Benny Motzfeldt at all.

    I am wondering if we are talking about the same thing - but I have no examples of this sort of glass to photograph to show exactly what I mean by Nazeing style-bubbles! The concentrated colour is in a wide, flat "halo" around the bubble - and it is either round or slightly elongated round - and about 2-3 mm in radius from the bubble.

    I do see a "particulate falling off the bubble", thin layer of colour on Marie's piece - but cannot see how it could be described as being the same as the wide flat halo.

    I'll have to try to find something dyed to try your experiment. We don't use anything with extraneous chemical agents in it!

    Sue — I can't forsee this being resolved, and, as it's irrelevant to the attribution of of Keith's vase, I suggest we just agree to see things differently.
