I think this is quite ugly  :(   

It does have quite a bit of age to the base though and is heavy. 4 1/4 inches tall and 6 1/2 inches diameter at rim. Any help would be great. Thanks for having a look .

No silver chloride there, just blue and white and browny splodges over a resist kind of base.
(By resist, I mean two enamels which are incompatible used together - that's how you end up with that sort of texture in the background.)
I've seen thes colours used in a resist way by Mtarfa and by Anthony Stern. I don't think your piece is Mtarfa, I couldn't say much about Stern - I don't know enough of his work.

Thanks Sue, is it the lack of bubbles which indicates that it isn't silver chloride ? I thought this might be from somewhere like Bulgaria !?....perhaps ?  ???

No, it's just all the wrong colours.  :)
Silver reacts with clear glass to produce yellows and ochres - the intensity of colour will depend on the concntration of silver present.

Silver nitrate is used to turn red glass brown, but it is still the silver that does the colour thing.

If any silver molecules escape acidentally during the making, they will often deposit on the surface of the piece in what is called "iridesence" (when it comes to Mdina anyway), but it is actually more of a mirror - but blues and yellows may appear because of reactions with glass - it's all stuff that happens in the heat!

It is also silver metal which can produce a sort of electric blue haze in a thick casing.

It doesn't look like normal enamels at all.

Thanks Sue, I didn't know it was silver molecules that produced the iridesence in Mdina  :D

If it weren't for the age on the base of this I wouldn't have bought it .....it was because it's hat- shaped and has age that I was thinking it might be worth looking into but I haven't found anything about this vase anywhere  :(

It does all sorts of weird and wonderful things, when hot, with glass.

 Yes, it's lovely to see it  :)  ...this brown looks drab and uninspiring    :(
