Looking for information about this glass plate.

As glass is not something I have a great knowledge of, I'm hoping others can help me out.  I will try to describe the plate to the best of my abilility.

'Frosted' amber coloured glass to the perimeter, with white glass to the centre with red, green and black 'decoration'.  It varies between 1/2cm and 1cm in thickness.

I had thought 'layered' glass, but was told years ago that it wasn't.

So any clues on where, when and who?

Base view.  PS : Sorry about the quality of the pics, it was getting a bit dark when I took these.

Your pics are excellent. I would call this amoebic shape - which would definitely mean 1960s 1970s or later. I would have thought the decorative effect came from cased glass, but it is difficult to tell. However the frosted glass is a bit of a poser - so far as I know very unusual for Italian / Murano glass, and not common for Scandinavian either - which would the the two places you would normally associate with a dish this shape, mid to late 20th century. Hope someone else knows more.

Thanks for your response.  I used the word 'frosted' because I couldn't think of a more appropriate one. It is semi-transparent, and definitely not a normal glass finish.  If it was ceramics I would say 'matt'.  

Even though it is glass, it has always had a warm, tactile feel to it - never cold to the touch.

I'm even more interested now to see if anyone can fill in some more gaps on this.

The shape reminds me of a Swedish bowl I have, although without decorations.

And if you google Swedish bowl, several come up having similar shape.

But may be something completely different as many countries have prob used the shape.

Googling wasn't all that much help.  Although I found that 'opaque' rather than 'frosted' is probably a more appropriate term to use.

Glass is cool, at the very least - could it be resin? Like dinosaur designs?

[5kazam]

Definitely glass.  Resin doesn't 'ping' as glass does (and I don't mean the 'ping' of crystal).  

Gosh, I wish you were in Melbourne so I could show it to you - then you would know what I mean.
