Topic: Controlled Bubble Jug

[chopin-liszt]

I'm 99.999% positive you have Biot, Nev.
I got my big bottle out and the rubber gloves and the floor cleaner and green scrubby things and I have cleaned it so I can see inside.
What you are calling the pontil mark is really not quite right, I don't think. 

The circle of "bitty" glass is far too big. And I strongly suspect, from the flat topped dome inside the hollow that it might have been a broken pontil mark that was subsequently put in a mould and blown again.
The bottle base flares out. The only way the huge hollow, with that ring half way up inside it and the flat top (or bottom) right in the centre, could have been done is in a mould.

So, a broken pontil scar would have stretched into the big ring we see. This would mean they had worked the thing from both ends.
I can only find one image online of the big stoppered bottle with the flared base. But it's on an auction site well-known for imaginative prices and for following you around for months if you ever click on it. So I haven't clicked on or linked to it.
The image is of a collection of pale blue Biot pieces.

Is it stable?  It looks quite narrow at the base - the kind of thing that might be easily knocked over.  Biot made/make lemonade and water sets and the jugs look to be very sturdy in shape.

Also to me the bubbles don't look right for Biot ?  Here's a champagne bucket with a mix of bubbles, some stretched some not.  They are quite 'watery' in appearance though and the bottle below shows the bubbles very well -

Was it the "dibby" image you saw? That was the only image I could find My bottle is very tall (45 cm without stopper) and the base is flared out, 12cm in diameter. It is not unstable. It has the Biot mark on the prunt on the front.
I think the bubbles in the champagne bucket look rather small for Biot, the other pale blue thing is small and I can't see it terribly well.

Sue, I suppose it is wrong to call it a pontil mark as they didn't use a pontil rod but made the piece on the blow pipe then snapped it off from there leaving the ring mark. flying free, it is quite stable despite the narrow base because it's fairly weighty at about 3 1/2lbs. I agree the bubbles don't look like any Biot I've seen which are much more numerous and irregular.

Biot items here as well .  No jug in that shape though.  Sue if you scroll your cursor over the blue bottle it enlarges the image part under the cursor and it means the bubbles can be seen really well on that one

Nev, I don't know ... the bubbles, the colour and the shape are not speaking Biot to me   But perhaps it was part of a different kind of set or something.  Also Biot do or did do, a small range of decor bubbles.  They aren't all exactly the same.  So there is that.

Maybe it's my copmuter, M. I'm not seeing the bubbles well.
I have been able to study my tall bottle though. The bubbles are "en masse" around the top, but get sparser and sparser as you go down the body - hardly any in the base, just a couple of small round ones.
And the bottom has been put in a mould after whatever bit was broken off, was broken off. I can feel the ring of sparkly bits. It's all been smoothed over, but does have a few deep chips around. It's been flattened in a mould - the only way they could have achieved the flat disc under the dome.

I would think the final size of the item would have at least some effect on how the bubbles appear. 

The shape of Nev's jug is the only thing that does worry me. But I haven't found any more than that one image of the tall stoppered bottle I have. It could be from a discontinued range, particularly if it was unstable!

Do you mean a bottle like this Sue?

Here's a labelled ice bucket in blue btw:

also photograph of all the bottles here:

https://www.annuaire-metiersdart.com/images/annuaire/1_LA-VERRERIE-DE-BIOT_2.jpg

One looks a bit 'tall and thin' (i.e. may or may not look unsteady )
I'm still not convinced about the colour or the shape or the bubbles though on the jug.

It's like the chairish image - but those pics are taken from weird angles and the base looks too narrow.
The same bottle in the link in your second post is much more accurate, with a "bellied out" bottom.
It's not really amethyst, it's an amethysty-y pink.
I'm not worried about Nev's bubbles. I've seen enough Biot, I think, to know they are identifiable but not consistent.
The blue is a bit deep, but I think there are several shades of blue used.
I am worried about the shape. 

And now, I've gone and accidentally clicked on a link to "that site" which will now follow me around like a bad smell for weeks.

they didn't use a pontil rod but made the piece on the blow pipe then snapped it off from there leaving the ring mark.

If that is the case they were using the blow pipe as a pontil rod. You can't blow without leaving a hole...
