Butter bell in marbled ceramic

Very beautiful butter bell ceramic whose enamelling presents very pretty mottling in shades green, blue, brown and off-white. Placed on the breakfast table, it will not leave indifferent! A nice craft that seems relatively old to me. The whole is in good general condition, no crack or big lack, but it does not hide its age: the bell has some small chips or ginnings on the enamel at the lower edge, the saucer has some small gaps and stains on the enamelling (some seem to me original) but also a larger shine (about 7mm) inside. This butter maker measures 13.5 cm in maximum diameter (at the top edge of the saucer), 12 cm in total height and weighs about 500g.
