Purple and clear lemon squeezer... http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=140472878159 - this strikes me as an oddity... anyone seen bi-coloured ones before or know who made them? It can't be sun-purpled like that can it???

If sun purpling could do that  :rah:

Looks like it is either enamelled, cold coloured underneath or more likely plastic colour coated.

Irradiated.... pretty sophisticated method needed to do that, starting with Manganese content.
Usually only used to attract a premium on old bottles.
 
Sunlight will do it from gamma radiation, but how could one shield to have zero effect where it is clear? It takes some time to change colour and not that dark.
I've seen gamma giergers go off scale when spent nuke fuel rods have passed by in their special shipping containers built to isolate alpha & beta partials.
I've dug up old bottle fragments here buried for years doing groundwork, and a layer of soil 500mm deep doesn't stop gamma radiation.   
But who has access to gamma sources to do that? Not a 'hobby' sort of tool you have in the shed.

X-Ray maybe... but again, who has or would go to the trouble?

Mercury Arc irradiation maybe... but an effect so profound? ...and why bother?

Sorry, bit sceptical on the irradiation possibility.

I was rather suspecting cold glass paint myself..... it would appear I'm with Frank on this one, something not right.

Yeah it just looks very odd, doesn't it?
