In an earlier 3-page message ("Help to id a paperweight please" - Sun Mar 06, 2005) a mystery weight was eventually identified as Alum Bay Glass, Isle of Wight.
Having originally baffled me (I had not known before of the "AB" impressed logo on any paperweights) I now find myself with two weights given as gift yesterday. One is Alum Bay Glass and the other Isle of Wight Studio Glass. Both have a paper label in addition to an impressed logo. So it seemed appropriate to include some details here.
I have no information of when my two gifted weights were made, but under UV light they do not indicate lead glass. For the Alum Bay weight this shows that it is not an "earlier" piece since information linked in the original message (see above) tells us that the company (at some stage) ceased using lead oxide as part of the batch.
Here's the two together:http://glassgallery.yobunny.org.uk/displayimage.php?pos=-6487
This is the "Flame" logo and label to the base of the Isle of Wight piece:http://tinypic.com/2jwimb
And these two links show, for the Alum Bay item, a) the label and b) the logo - after peeling back the label:http://glassgallery.yobunny.org.uk/displayimage.php?pos=-6489http://glassgallery.yobunny.org.uk/displayimage.php?pos=-6488
And an image of the logo highlighted for easier viewing:http://glassgallery.yobunny.org.uk/displayimage.php?pos=-6501
The Alum Bay label shows the Needles Lighthouse against the last couple of a series of very thin and pointed rocks at the western end of the Isle of Wight
For the Alum Bay "AB" logo, it would appear that the definition may not be very good in many cases. In the photo shown here the letters are set to the side of the circular area causing the "B" part to be quite indistinct from many viewing angles. Also, if you see the letters as embossed (raised), that is an optical illusion - they are actually impressed, with three raised nodules, one for the upper centre of the "A" and two for the inner parts of the "B". (The Isle of Wight "flame" logo is raised.)
Clearly the "swirled" design of these items is quite typical of many different studio pieces from the 1970s to the present time. Indeed, many people may think "Mdina" when first sighting a paperweight like these, as that company seems to be more widely recognised for its "swirl-type" designs.
My own view of the Isle of Wight and Alum Bay paperweights of the type shown is that they are standard gift items and as such do not (yet) receive recognition within paperweight collector clubs. The two shown here both have unintentional air bubbles included - with the Alum Bay example having an unfortunately large bubble to one side.
Perhaps the general art glass from those companies does have a wider recognition?
