;D
:huh:
It's actually quite hard to work the patterning out - each different angle it's seen from makes it look almost like a different weight.
Silver nitrate was used to turn red glass brown, so you still get yellows and ochres, and sometimes, cloudy bluey effects.
Given the colourings, I'd suspect late '70s - midish '80s???????? This is merely my opinion. I may be wrong, I can't really work out the shade of red or how orangey it is and I can't work out how the reds and browns mix - is it streaky-cloudy or is it blobby?

Hi Sue, the casing is pale green the pattern I would describe as blobs which give a mottled effect the blobs are more orange than red, some are yellow the swirls around the base blue and yellow a stream of yellow near the top ends with the bubble you can see. What happened to the saying a picture paints a thousand words :sun: Unless of course it's just my photos are rubbish :-[
Thanks for looking Chris

They aren't desperately special. I have three and I rather like them because they have more depth (and more colours) to them than some of the blue and yellow ones. The bluish (to me) casing is common to them all.
Once you've realised they're Mdina, you start to see more of them, as they're not all marked. Sue's date is about right; I have one with a white paper label.

I wouldn't describe the casing as "pale green" - that sounds as if it was on purpose, a deliberate colour, rather than simply slightly iron-contaminated metal in the pot. The yellow and ochre colours, and any cloudy and diffuse blue "glow" arises from silver reacting with and in the "clear" glass. That's a given, really when silver salts are used to produce colours.
I was wanting to know if the blobby bits were deliberately blobby or if they arose from chemical reactions between the sliver and the red.
And it's very difficult to portray a 3-D object in 2-D, and the camera really, honestly does lie, contrary to the old myth, Chris. ;D

Thanks for opinions grateful as always, just thought ( hoped ) it looked a little different and maybe came from a particular range mainly really for accuracy with my listing.
Chris :sun:
