British & Irish Glass / Re: annealing crack in IOW Studio piece

I guess that's why then. I've had a better look and can't see any impact mark.

Thanks yet again for your help and for sharing your knowledge.

I remembered last night that white is a colour of enamel that does cause problems in annealing because of it having different cooling rates to other colours.

It cause loads of problems for wfs with the stuff they were putting a white rim on and they ended up giving up on it.

I think we're up to knowing of 8 of the tall amethyst bottles.
There are about 40 Crizzle Stones, currently known.
Of these blue pieces, there's yours, John's, Mike's, and possibly 2 or three more?
There are perhaps about 10 Zig-zags known?
(John keeps up to date with things and watches the market far more than I do.)

The same as mine but with a clear base, the pattern of the trailing is the same too. I wonder how many there are yet to be found.

I see what you mean. I have some and some are good, others similar to yours. I do like them all though, they still have character.

Thanks John, I think you're right. It is within the glass and looks a lot worse in the image. My family couldn't find it and sometimes I can't unless the light is right.

It's the only piece of blue and white swirls I have at the moment and wasn't expensive. Definately worth having and an amazing colour. Nice that it's signed too.

It does ring a bit but not the same as a globe vase but I think it's more the shape.

Many Thanks for your thoughts Alpha, I am inclined to agree after been informed of a link via friendly associate by email which shows some experimental weights very similar to these by Strathearn. Sorted.

If it's only in one layer, it will still ring when tapped, will it not?
Maybe I ought to have a closer look at some of my Aurenes, especially the strapped ones!
The only thing I have with a humungous crack in the base is a massive tortoiseshell bell vase, I have assumed it came from an annealing problem originally, because of the size.

The crack in Andy's pot seems to be at two angles rather than a single line?

I have had a few IoWSG items with small cracks in them, pretty sure two of them were aurene, one was definitely a strapped aurene vase (another was pink and blue swirls). Each time the cracks were hard to spot and on really close inspection I could see that they were only within the inner layer of glass, the layer that in the case of aurene holds the colour.

In this case if there is no indication of damage on the surface associated with the crack then I would assume an annealing fault resulting in a stress crack.
