Topic: Please help with ID vase : ID= INCA vase

This vase has no pontil nor ground base so i assume that it is pressed ( no obvious seams). The glass is heavy and quite thick it is 28.5 cm tall.

Yes, it is pressed. It is known (to Carnival Glass collectors) as the INCA VASE. I believe that it was made in Czechoslovakia circa late 1920s, early 1930s. It is known in Carnival versions (in marigold and black amethyst) as well as in non-iridised vaseline and no doubt other non-iridised examples.

It's a stunning and impressive vase. Congratulations.

Thanks Glen, I would not have thought of this as being part of the carnival glass grouping- it must include more than i thought. Ill get searching for the Inca name.
Oh,it also comes in pale green as I have another.-I guess that is the vaseline colour you mentioned.

David, it's probably only Carnival collectors who use the name Inca. We are a passionate lot when it comes to taking over glass and naming stuff.  :lol:

Do you know anywhere online that I can see examples of any other colours of the Inca pattern?

David, it's a pretty scarce vase, and I researched as much as I could when we wrote about it in the past. I don't think there's much online about them - I think I've possibly told you just about all that I have ever managed to glean. We wondered for years who made the item, but by comparison with another vase we later acquired we were able to make the link with Czechoslovakia. I have always suspected Inwald as the maker but have no absolute proof.

Yes. That's me.

I'm struggling to understand just how this was made, but I can't see how it could possibly be simple pressed.  Any pressed article must be designed so that the plug will come out.  Plenty are then re-shaped afterwards to cup in the top, but on this one the retention of definition of the pattern is too good for that to have occurred. In addition the well-defined top would be impossible.

One possibility is "pressed and blown" - a process commonly associated with mass production, but I suppose someone might have adapted it.  A very heavy pressing is made (enabling the top to be formed), and then, handling by the top ring, is quickly transferred to a blow mould of the finished shape and surface pattern and then blown to finish.

Yes, that's it exactly. My fault for jumping too quickly and not explaining right. It's made in exactly the same way that all the bulbous "pressed" vases are made, water pitchers too. They are blown into the mould. Sorry for confusing the issue. We have explained the process in "Carnival Glass, the Magic and Mystery" with reference to vases etc.

"Instead of using a plunger, the hot metal was in some cases forced into the mould by blowing air into it. Many water pitchers and large bulbous vases were produced in this way".

Apologies for being unclear earlier. My fault for trying to do too many things at once and not concentrating on the task in hand.

And I forgot to add the most important thing, so I'm adding it now in an "edit" - THANK YOU Adam  :lol:
