This vintage set of 4 copper measuring pans with brass handles were made in Portugal by Tagus, a popular and sought after maker of this type of kitchware. Desirable in modern times as stylish kitchen display items due to their aged copper patina with areas of vert-de-gris, they allude to that sophisticated country house aesthetic. Recommended for display purposes due to age and wear and to protect their patina. Please see all images, including scale image as, for clarity, these pans are not full saucepan sized pieces. A slightly older copper cup set is also available, currently, in my listings.
