The object in the photos is 23cm high by 13cm diameter and weighs 1.56kg. The outside is satin finished, except for the applied handles which are shiny, and the inside becomes progressively shinier from the top rim on down inside. The feathered trails in orange, blue and white are almost completely embedded, although the change in texture can be felt by a finger lightly dragged over the surface. The base is roughly ground.
The main material is truly black, and completely opaque as far as I can tell. Sometimes I wonder if it is really glass!
Where does such an object come from, and when would it have been made?

Bohemian & Czech glass could be an option.
They made the Hyalith glass in the 18th century (started to I mean), which was like an imitation stoneware. That might be a starting point for you?

I'm just chucking thoughts at this...
It really really does look "classical". It is a bit reminiscent of ancient Phoenician glass - from before blowing, when things were made on a core.... but not that old.
Could it be one of the rather lovely top-end replicas you can sometimes get in museum shops?
-
Not sure it is glass - it could be hi fired earthenware which takes on a glassy appearance. I vote against hyalith because that has all the aspects of glass....
-
That base is ceramic not glass
-
Black clay then?
I can't see any edge where enamels would end.... and Trevor says he can feel a texture where the feathery bits are..
Trevor - do you have a very, very strong bright light to hold it up against? any sunshine your way? (but remember to protect your eyes)
I agree, the base does look ceramic, but glass could have ended up like that... ???
The handles look like glass...
-
I had a piece of Will Shakspeare glass that was black and look like that base and that glass texture.
I vote it's glass :)

Thanks all. This is more exciting than I thought.
Sue: There's no sun to speak of here today. I took the brightest torch in the house into the darkest room to see what light might come through. After a few Schrodinger-like moments of doubt that the torch was working, I convinced myself the material is quite opaque.
I've added a few close-ups of the handle, the feathered trails and the base texture. Maybe these can help in telling whether it is glass or ceramic.
The fourth photo shows the base of a small vase by the noted West Australian glass artist Gerry Reilly in which the pontil scar has been ground out leaving a textured surface like that on the object in question. The difference is the bright torch shines through the material showing the deep blue colour that is evident from the internal appearance of the vase.
My experience is that 'black' glass is usually a deep purple and does transmit light if only weakly. I would lean more towards the conclusion of ceramic if I could understand how such feathered trails might be made. It really looks to me like they have been trailed on, then dragged through up and down and marvered to include them into the parent material - all before or while the item is expanded to its present size and shape. I cannot see how that would be done with ceramic material, at least not without making a big mess.
Anyone suggest other tests that might be done?

Looks like Azerbaijan or Baijan glass to me.

It still looks like ceramic to me; you can see the grains. It's amazing what you can do with glaze...

It is 10 years since I posted this query. I have solved several other queries on here after 7+ years (for myself and others), so reviving this one is only a little stretch.
A recent post on the Art Glass Collectors group by prominent US collector Louis Edwards asked about a similar item of the same size and finish and convincingly by the same maker. The base treatment of his example should dispel the impression that they are ceramic, even when relying on photos. (His photos shown here with permission.)
The questions remain: who made them, where and when?

Reminiscent in parts to both the Phoenecian and Nerox style wares from Fratelli Toso (early and mid C20 respectively), perhaps inspired by.

Very reminiscent - and utterly gorgeous.
Why do auctions never show base pics? >:(
