Yes, you are both right, i think what threw me was one side of the vase was smoother than all of the rest of the vase and it gave it a very odd appearance, when i looked at it in daylight it was obvious.
Well it is now in pieces!! as i took it out onto the patio and the dog spotted a squirrel, i ended up flat on my toosh!! and the vase kissed the ground.
the lesson learned ? leave the dog indoors when looking at glass outdoors
