Hi
sorry been away for about a week
thanks so much for the extra pictures -makes a world of difference
The first one I think is definitely a lamp base (reduces the value a bit -not a lot) its doesn't look cut down - I was wrong there. The pontil looks quite good, but impossible to be sure from a photo (need to rock it and see how the light illuminates the different surfaces)
I see the yellow has been polished out behind the flowers (on the inside of the vase) -that's a good sign and helps tell if its fake.
you can do a bit of experimenting for yourself.............
Try to get your fingers inside the vase an run them on the inner surface where the yellow has been polished out - if there is a ridge between yellow and clear it is probably a fake, if there is a smooth interface then its very likely good.
OK that's the good news I hope.
The landscape
it's a very high probability is true Galle from the picture
but the shape is a bit unusual and the signature looks quite high on the body for such a small piece -furthermore the way the landscape decoration finishes near the surface looks a little odd. All this would make me very worried that it might have once been much taller. -and here I stop - as that's a think that can only be told by handling.
sorry
hope this helps --you can tell a lot from good photos like these, but it would be impossible to be sure on these pieces without handling them!
as for dates
that is a very interesting subject at the moment as different academic experts have different views on dates
-I have books that would suggest these are c1900
-I have other books that would say they are 1905-1914
-a recent book suggests they are 1918-1930
again sorry I can't be more help
cheers
Mike
