Topic: Czech, Japanese, Polish, other? Sommerso vase

[Jeffingtons]

Bought this years ago and it's finally made it out of my loft for a clean and a bit of love. Has a lot in common with a lot of vases attributed as Czech on the net, but the polished pontil seems at odds.  Approx 25cm tall and heavy. It's not the best vase i own by a long shot but I like it more than I used to. Any help appreciated

My guess would be Japanese. It's also cased rather than sommerso

There are three colour layers. It's just not very clear. There's a thin layer of yellow between the red and the clear layers which you can make out on the lobes

It's still cased. Sommerso means submerged and is a visual effect that isn't seen here

Definitely Japanese. I don't think a specific maker has been pinned down.
Your one is pretty much the same as the one on the left which has a Japanese export label.

They are made in different ways and share very little other than colour. Jeffington's is blown and the shape hot worked by hand. The Japanese vase is blown into a mould to create the shape, much simpler process. They are unrelated.

Well I stand corrected. I knew it meant submerged, and with yellow layer being between the red and clear layer, I assumed it was a bad attempt at copying Murano sommerso.

Sommerso is a difficult term to use here, I would also expect there to be two distinct layers of colour, one within the other. It is possible in this case that the yellow is a result of one or the other of the following. Either where the red is greatly' thinned' (through the production process) and far less dense leaving it looking much lighter/yellow or maybe the colour is heat struck - where a colour will change according to the amount of heat used during production. In this case the rim would have been reheated so that it could be worked into shape.

Sometimes it is useful to inspect an item really carefully with a bright light placed behind, the light on my phone works well for this, look really closely and move the item or light source about. That way you might be able to see if there is a layer of yellow around the whole piece.

I will add my tuppence.  It is almost certainly Japanese.  Reasons include the neat horizontal bumps that are never in Murano or Czech glass - they like more freeform.  The Japanese also love Red and Orange, and most of their hot glass is in my opinion far better than Murano.  Companies like Kamei, Sanyu, Iwatsu, Hineri, etc. all made lots of clear cased glass.

I've been looking through a lot of Japanese glass online. No confirmed matches yet. I am liking the look of Kamei Rainbow glass though. Rather pleasing to the eye.
