What you need is a bit of sunshine - that's got some uv in it. You're looking for a limey green opaque glow.

Early evening sunshine is best

Hi,
I think that the green enamel used has got the Uranium in it, it really is the strangest thing. I don't think the coppery bits at the top are aventurine either,  it look more like a reddy orange enamel with lots of tiny bubbles that make it look metallic. Today it looks like "Peacock feathers" colours.

Must try to get a UV torch,

stunning piece and one of my favourite shapes, damaged or not a real beauty , well done you,

The "aventurine" in the Perth cylinder vase (and the chalice), isn't copper or gold coloured, it's the colour of bronze, and all clustered around the bubbles, so it must have been particulate within the molten glass.

(I saw a fascinating science programme about bubbles in liquids not too long ago; and how particulate matter will adhere to the surfaces of bubbles in liquids, and while the programme was more about using this phenomenon along with ultrasonics, to deliver drugs directly to the point of interest, but it was very relevant to the formation of bubbles in glass, and how we end up with enamel haloes around  them.    )

I've not a clue what it might be. It's not copper, or gold, or mica flakes from Woollies.

Yes, I know what you mean, it is clustered around the bubbles to amazing effect - any techies out there to tell us how it's done?
It reminds me (but in a much more spectacular way) of the Nazeing bubble halos.

By the way, ordered a UV torch today - will post some more pics when it arrives

does it have silver chloride in it?  it  remind me of some of the WMF Ikora pieces.

Hi,
I don't think it has silver chloride - it doesn't have the iridescence or the look of my Mdina bits with it in. I think it's just a combination of all the bubbles with the enamel halos around them and the possible uranium glow that gives the effect. But it changes colour with the light like nothing else I've seen - It's like the Alien Vase

It's all to do with surface interactions and attractions of different valencies...
A little bit like how detergents work.

Surfaces and how they actually operate at the molecular level are a relatively new (and fascinating) field in science.

Yup, these things change the whole time.

That's why it's so horrible having to see them stuck all static, in fixed lighting, through bullet- sue-, garym- and gary-proof glass...

You don't really get to see them at all.
