Topic: studio glass vase spiral design with satin base, is it by Jill Devine ???

[flying free]

I've searched on this and not been able to come up with anything concrete.
I like it because it reminds me of Karlin Rushbrooke or Will Shakspeare in the use of the heavy satin glass combined with the plain glass.  There is a lot of reflection from the blue in the satin base, and although the finish on the satin part looks to me to be the same, because of the colour it doesn't quite 'match' any of the pieces I have by them.  Does anyone recognise this at all or have any leads I could follow up please?  It is very heavy and measures 12cm tall by 9.5wide.
Many thanks

Interesting piece. Nice use of marvered frits to give a glinting look. Wrythen stripes a nice touch too but my favorite part is where the "half post-formed" body meets the separately blown base. I still can't quite get my head around how they do that. Normally its just the neck.
Not unheard of, but odd for a studio piece to be unsigned. Perhaps not as "intended" and therefore not considered 1st quality, not that I can see anything wrong with it.
William Walker did several pieces with icy-looking translucent white satin.
I guess that many studio artists have tried their hand at the post formed technique but the only ones I know of for sure are: Steffan Gellerstedt (Stockholm) and Bruksforshyttan AB Robertsfors, FLARKEN, NORRLAND, Sweden (and of course Michael Harris but this ain't his.)

I've decided to eliminate this expression "half-post" from my vocabulary, Paradisetrader :kissy:
(again, I need a *smug, know-it all* emoticon!)

It is partially cased.
This describes it perfectly and avoids any sort of confusion,

 ....and any reference to some ridiculous, convoluted and utterly WRONG descriptions which have managed to sneak their way into glass terminology at some time in the past.
I have no idea who invented and then circulated all this "half-post" or "on the post" nonsense!

The outer case is not made first, then the inside bit put into it.  

The inside bit is made first, then it is partially cased. Simple!  :clap:

Half post is a valid technical term used in bottle making. Bottles have a large body and a small neck - so the volume of glass around the body is quite large compared to the neck. In half-post forming, a bubble with neck is pre-shaped, then a gather is collected around the bubble and blown out. If done properly, an even thickness over body and neck of the bottle can be achieved. Just do not use this term outside bottle forming....

Now I need a *stubborn mule* emoticon.
I'm still adamant that I'm going to use "partially cased" to describe this method for whatever purpose.

But I do really appreciate your excellent description of the one instance where that "other" name is relevant, and why, Ivo. 
  Something else I can nit-pick about in future......

Hi, Pete thanks for your lovely comments and thoughts on possible sources.  That's given me some new areas to search both in terms of technique and also makers - and I've discovered glass I hadn't seen before and wouldn't have found if not for those leads. 
It is really heavy I've just weighed it and it comes in at over 2lb (900grm ish).  Has the feel of the kind of  glass Karlin Rushbrooke makes and the satin is really very similar.  Be nice to find out who did make it eventually. 
Sue, Ivo thanks for your explanations of casing and the techniques used.  I've always wondered how Benny Motzfeld Randsfjordglas vases got that appearance of the matt neck piece and the clear bubbly glass appearing to be dripped round the necks - would that be the same way as the bottles were made?

Yes, absolutely. They're lovely pieces, aren't they? I have a few.

Does anybody know anything about Jill Devine?  I've a theory about this vase - the theory being that the person who made it was left handed.  I've based that on the fact that all the vases I've come across have spirals which turn to the right and on my assumption that more people are right handed than left handed therefore they are probably made by right handed glassblowers (obviously I'm ignoring my other theory that glass blowers, being artists, may well go against my perceived population theory and be predominantly left handed, because more artists are left handed than right handed).  On this vase the spirals turn to the left.  Therefore made by someone left handed... bear with me on this one.  
Tonight I found a vase that has a glorious transparent glass 'top' that appears to be as glossy as this one, but that also has a satin glass 'frill' wound round it from the bottom up.  It is wound round anti clockwise i.e. starts at the bottom and goes to the right, winding up the vase.  So, with my theory in mind, (and a complete lack of knowledge of glass making techniques,  as I said... bear with me) I deduced that the person who made it may have been left handed.  And it has the combination of satin glass on transparent glass.  It is signed Jill Devine.  The information I have found about her is in Charles Hadjamach's 20th Century British glass and apparently she worked at The Foundry at Royal Brierley, which was set up in 1986 but only lasted a short while before being run down.  I think I read it correctly that The Foundry was The Studio at Royal Brierley?  So... could Jill Devine be the maker of my vase?  the pontil mark finish appears to be similar on both vases as well although difficult to tell really.
Any thoughts or  information very much appreciated.  And a request to the mods please - would it be possible to add Jill Devine?? to the title of this thread please, if someone has time to do so please?  Many thanks

M, I raised this question about spirals and left-handed glassmakers a long while back here:
http://www.glassmessages.com/index.php/topic,512.msg2021.html#msg2021 and Adam A was kind enough to add his thoughts on the concept here: http://www.glassmessages.com/index.php/topic,512.msg2636.html#msg2636 - it may be helpful in your quest or then again, maybe it won't be!

ah...thanks Anne. Well bang goes the theory then   I'm still hopeful I may be able to attribute it to Jill Devine though.  If one of the mods reads this, please would it be possible to change the title to include her name and a question mark if you have time.  Many thanks.
