I heard today through the grapevine that Effetre's famous/notorious/love to hate 254 Purple (Orchid) - otherwise known as EDP - Evil Devitrifying Purple - is done. There will be no more. Whatever scraps you have of it - hang on to them - because Effetre will not be making anymore.
The way I heard it is that changes to regulations prevent them from melting one of the key ingredients - so they will not be able to produce it.
So - enjoy what you have folks! All those cool reactions w turquoise and other colours - all that will go too.
