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.
