Topic: H Wilkinson 1905 patent. Uniform spots

[Ekimp]

Hi, in Hajdamach, pages 278/279, a technique is described that was patented by H. Wilkinson in 1905. The technique involved winding a coloured glass thread onto a vertically ribbed shape so that the thread only sticks to the peaks of the ribs. The shape is then spun and heated. Spinning stops the thread sticking to the shape in the troughs between ribs and heating breaks the thread where it hasn’t stuck, the broken threads melt back to a blob or spot where it adhered to the rib peaks. This gives an effect of vertical rows of uniformly spaced spots. It can then be blown and shaped as desired.

Could someone point me in the direction of makers that used this technique? Preferably later more modern looking pieces rather than frilly delicate Edwardian type stuff, maybe mid century Murano or studio glass? Was it widely used? Are there key words that I could search for for this technique as I haven’t had much luck with ‘Wilkinson’ (have to specifically exclude Wilco from the search ).

I have found this one that looks like the technique was used but the description says the spots were cameo cut (but not sure I believe that). https://www.liveauctioneers.com/item/68668354_modern-design-black-studio-glass-vase-cut-white-spots
Thanks.

Some examples in the following  threads, flying free goes into some depth in the second.

Can't think of anything modern offhand but have a vague feeling Royal Brierley may have used the process and if so I bet Keith has an example!

Thanks for your reply John, I’m a bit annoyed with my poor searching! I did search the message board but think I used google image search (which didn’t find those threads) instead of the boards own search function. There might be some clues there, Orrefors is mentioned.

The suggestion of Royal Brierley might be useful too thanks, I’ve just found the example here: https://legacyantiques.co.uk/royal-brierley-studio-glass-scent-bottle.html that is more the sort of thing I was looking for.
Mike.

Not much like the one in the first link, here's a few, there is one with black 'spots' but can't find a photo ( right again John !  )

[Ekimp]

Thanks for the photos Keith. The spots don’t seem to have formed circles and look more elongated, I suppose they must have done that on purpose. Interesting that on the bottom of one, you can see the unbroken thread spiralling around before it goes up the sides and breaks up.

Do have a green spotted atomizer and a large bowl with black spots in the same pattern. I believe the glass artist Deborah Fladgate also made similar stuff.

Thanks for the Deborah Fladgate name. Looks similar to the Royal Brierley stuff with elongated spots. https://www.glassmessages.com/index.php/topic,63699.0.html

There is another one here that looks like it might be an early example with fancy dots.

Probably worth mentioning that the Chinese also use this technique by the look of it. There is an example here that has a modern looking barcode label on the bottom, imported by Circle Glass LLC New York, made in China. There is a pink conical type cocktail glass with clear stem and a matching ovoid vase. It looks like the rims maybe fire polished but it’s hard to see.

Waterford Evolution also uses elongated spots like the Royal Brierley examples:

Ekimp I came across that Waterford design in the last few days and thought of the thread!  So a coincidence to see it pop up today
