I think I'm a bit confused as to what is a 'seam' and what is a 'fracture'. Tim talks about what he thinks are fractures on the 4 faces of the vase... As it is a pressed piece, they could very well be the seams (as he's told)... and here is my problem:
Yesterday, I was lucky enough to get my hands on an amethyst 915/200 vase. I can see two clear seam lines going down opposite sides of the vase (not on the lens or face, but on the corner -- see 2nd picture). These seam lines cannot be felt from the inside, only from the outside.
There is also what I believe to be a 'fracture' on each face, beginning approximately 1cm below the rim, moving down towards the bottom of the lens. These lines are not uniform -- each differs from the next as to position and curve. (See pictures 3 and 4 for examples.)
Could Tim have been right? As they appear on the faces, perhaps they are fractures and not seams. (By the way, the 'fractures' in my piece can be felt on the inside.)
One more question: Was the bullet vase formed using a 2-part mould?
Thank you -- especially for you patience with me
