Blue enamelled sandstone teapot

Here is a enamelled sandstone teapot. This vintage piece is in perfect condition, is not signed, but is adorned with beautiful colors that have made it one of my favorites: shades of blue and gray / brown that ensure a unique character. It is 17 cm high, about 15 cm wide and its depth (from its beak to its handle) is 22 cm. It weighs about 1, 250 kg.
