Topic: Are these USA ebay items MDG ? The second example is superb !

[chopin-liszt]

Very definitely a Malta Decorative Glass label. It says so on it,   it has MDG around the cross shape   

- you may notice the cross is a different shape to the one used at Mdina? - the tails of the ends of the arms of the cross have an angular indent in them.
If a prunty indent is made using a cross shape on a bit of MDG, it also has this feature on the arms.

And (oops, managed to miss the link!) yes, that is a blue MDG pot in the listing. It's not nearly as nice as the globe, is it?

Cheers Sue,

No it isn't (nice though) , the blue globe is well worth the asking price IMHO (very tempting !) Interesting to know about the prunty indents .

Is the broken silver leaf effect patterning silver leaf or is it something else ?

Ta, Mike.

Absolutely not! 

It's an incredibly thin layer of silver chloride melted over the surface of the glass, the silver reacts with the glass, colouring it, then it has been further blown to do the stretchy effect.

There's a good close-up of the foil-like effects on a bottle I posted pics of in this thread - but you can see the striations of the chemical reactions between the silver metal released and the hot glass in the patches - they're silvery/yellowy/bluey - not silver metal.

Thanks very much Sue for the explanation, I can see what's going on now (I think) ! The patches of silver chloride go from silver to brownish yellow/brown and the brown reaction seems to congregate in striations within the patch . I don't think this would happen at all with a just straight silver foil/leaf application.

I have learnt so much and thanks to everyone for all the input here and on other threads , such an interesting duo of topics    !  Mike.

Well, yes - but with the patches which look silver, they're actually pale yellow and a grey-ish blue, where the colour is very, very thin - but in the deep brown and ochre patches, the colour is deeper, (obviously), because there has been a much higher concentration of silver metal released.
All the tectonic plates are glass reacted with silver.

Thanks so much Sue , I fully comprehend the wonderful subtleties of this gorgeous art !
