The bottom is factory ground flat. It has no mineral deposits or stains.
Ware on the bottom is commensurate to it's age of well over 100 years. This Brides Bowl measures 11 3/4 in diameter.
The base measures 3 3/4 in diameter. Any unusual light or dark spots shown in the photos are from camera glare. In one of the crimps there is a small line that has carbon dirt in it. It's very hard to find and you have to hold it to the light to see it.
It's shown in one of the photos. It does not detract from this beautiful Brides Bowl in any way. There is also some loss to the gold decoration. Overall this piece is very nice. This will make a great functional accessory to any Victorian home.The item "Victorian Era Gorgeous Art Glass Bridges Bowl" is in sale since Monday, June 8, 2020.
