Haha yeah true!
It might sound very stupid, but for me it's one big "game of memory".
I've googled thousands of hours really.
And learned by it.
In the beginning I saw just a blue vase.
No idea what it might be.
The I just google something like: "antique blue vase - *shape* - *color*.
And just went on for hours :p
I haven't read a any books. I just do it by pictures :p
I have 2 opaline books but they are in French.
And translating took me way too long to get through.
But the glass in this topic...
I believe I'm right on the date and origin.
It's just the value that I can not find.
Sometimes you see these things very cheap. ($ 150-300)
And sometimes the prices are sky-rocketing. ( + $2000-5000)
I'm not sure where this depends on.
But most "islamic bohemian" glass I see is either clear glass or overlay/überfangen glass.
This opaline/alabaster glass is a little harder to find.
So I may have a good thing going on here.
But still not sure
