That's glass. And it looks nothing like the first two pics!
Dear Edward,
It is easy to see what something looks like when you have it in front of you, you can see what the photograph is supposed to show.
All we have is the image and when we
don't have the real thing to guide our interpretation of the image we can make a lot of mistakes.
The yellow base, with the dark surround looked decidedly ceramic. And there are ceramics that look like this vase.
Glass is difficult to photograph well.
