Five ancient potter's mazagrans in enamelled sandstone

The five mazagrans are in perfect condition, no gaps, no cracks or splinters. They are very well made, were shaped by hand, then enamelled by a potter. They are marked on the hollow reverse, with the brand of the workshop. They are all different, not quite the same or the same size exactly. Beautiful rich and warm enamel colors. They are heavy and stable, both rustic and refined in appearance, very authentic. Production of the first half of the twentieth century.
