Gary, is the pontil mark /button on your bowl highly polished? The photo may be deceptive, but it looks to me as though the base on the purple/white bowl is highly polished but the button pontil mark is actually finely ground but unpolished, i.e. not clear and shiny see-through.
I'm asking because all the bases on my vases are shiny polished but have a finely ground pontil mark, matt not shiny see-through and I'm trying to clarify my understanding of what constitutes an un-finished base and what doesn't if you see what I mean.
thanks
