Topic: bottle-green enameled decanter.

[Paul S.]

I suspect British  -  seem to recall having pieces this colour back when I collected  -  the glass is low quality and possibly mould blown - the rim is particularly noticeable for it's deformed shape.     Judging by internal neck wear, this one did have a stopper earlier in its life, but unfortunately long since gone.           Fair amount of base wear, and having said British, the pontil scar is possibly one of those snapped bubble type scars, so could be Continental I suppose  -  do I recall that Continentals used a hollow pontil rod, as opposed to the British solid rod?? 
I recall that the Continentals used bottle-green for their white wine glasses, so perhaps this too was for white wine, but that's a guess.                 The white enamel and gilded decoration is seen commonly on this type of glass - quite attractive albeit rather naive - but a great piece of Edwardian - early C20 glass (I think):-)

The enamelling is typically Bohemian from around 1900, it's not quite right but it's supposed to be Lily of the Valley, a common design. The French, particularly Biot, used a hollow pontil rod, I think yours is possibly a solid rod.
