At a guess the vases used are all pretty thick, which gives them
definite edges.  Also if you are shooting against a white background
you need to check the camera is exposing for the subject, not the
background - but I expect you knew that.

Fine a really thick vase and see if it helps.

I agree the examples look like they were shot on a back-light table,
with some front light as well.
