I just love vaseline glass (which we call Ouraline over here). I have a few pieces, including a huge centerpiece weighing a few pounds.
Alas, I still don't have one of the grails of absinthe collectors : an authentic vaseline absinthe glass.

Yeah, it has been proved quite harmless. Since it is still produced "en masse" in the US, as far as I can recall they made a study on vaseline glass transporters (they handle a lot of it) and saw no harm on the long term.

I do find this gizmo reaaaaaaaaaal pretty ;p
