hi, is it at all possible for you to resize your photographs so they show as 600x400 and that way when one clicks on them, they will enlarge so the detail can be seen.
Is your vase green when held up to the light btw? Also is it possible to have a clear picture of the base of the vase please? and a description of the finish pontil mark etc?
Deep in the recesses of my brain, I seem to remember reading somewhere that Loetz????maybe, did a something similar to this... I'll go have a look round and see if I can find a reference.
