here's an example of a capodimonte item marked Ardalt Italy. Please never confuse your pottery with Ardalt Lenwile Japan, which, while of nice quality is not even close to being the same. There's no connection that I'm aware of.
http://www.ewolfs.com/past_auctions/feb_catalog/425.htmlBecause I can't "see" your item, I can only guess. But if you were to search for yourself, or seek other help, which I recommend, lean towards searching for capodimonte pottery. There's Capodimonte and capodimonte with a small "c". Over the years as I've helped folks search for Ardalt I've found very little. May have been a small pottery in the Naples area. The few items I've found have been quite lovely.
I will continue my search, but for now, I thought you'd like a "heads-up" on your continuing searches. KB
