Used as an incense holder. This item has been in my family home for about 80 years. The inside has a verdigris patina. The material appears to be copper, as the cross-section of the bottom is yellow (see photo 5). It has a substantial weight. Dimensions: Width: 14cm Width: 10cm Height: 18cm Thickness: 8mm Weight: 936g There are no scratches on the outside, but it has been used for a long time. If you are interested in antiques, please consider this item.
