Clear cased Aqua bottle vase with fine bubbles
« on: November 03, 2019, 11:26:07 AM »
4" diameter x 4.75" high.  Fairly heavy for such a small piece - 488g.  Flat polished rim with bevel to inner aspect.  Slightly textured concave base with a partial flattened polished foot rim (barely visible).  Streaky fine bubbles in the aqua glass - these extend into the clear layer where the aqua and clear glass meet, which can be seen in the picture.  It seems quite well made, but there is an inclusion at the bottom that looks like black ink.  Would the bubbles be bicarbonate?

Colour shows well in pictures, except first one.

Thanks for looking

Plucking a gut feeling out of the air, Hadeland or something related?
I've definitely seen this finish on Benny Motzfeldt pieces. It is a Benny-ish sort of shape and texture of glass - but I'm not keen on the bevel. That does not fit with her work.
So I'm generally thinking Norway. :)

Thanks for the suggestion, Sue, I hadn't thought of trying Hadeland. The Ingrid series appeared to be a good match for the colour, but no bottle-shaped piece in the range, and the rims aren't right.  I can see a lot of similarities with Benny Motzfeldt pieces, so will follow that trail for now and see where it leads.

They are not sodium bicarbonate bubbles.  :)
I learned on the netflix series "Blown Away" that sodium bicarbonate produces what I have always called "Nazeing style" biubbles - the kind with a halo of dense enamel around every bubble.
It is demonstrated in the episode where lampshades are made.

Do you know what else can produce the really fine bubbles?  It was the halos around the larger bubbles on the base that made me think of sodium bicarbonate.  I thought there might be a clue in the base where the coloured and clear glass meet, as there are some "stray" bubbles into the clear.  I noticed the same feature on one of the Benny Motzfeldt pieces.

There's been talk of potato peelings, carbon powder and suggestions of petrol that I can think of, off the top of my head just now.

During the latest talk (at the fair on Sunday) some of us were slightly skepctical of the idea of petrol and very hot glass getting together...

There was a very long discussion here on bubbles early on. I'll see if I can find it.

I've found one, but I'm not sure it's the one I'm after.
