Mid-Century Modern Lava Glaze Interconnected Ceramic Serving Dish Set

This appears to be a set of four interconnected ceramic serving dishes or bowls, likely dating from the mid-20th century, possibly the 1960s or 1970s, given their organic, free-form shapes and glazes. Each piece is crafted from pottery, featuring a dominant earthy brown exterior glaze with a textured, almost carved appearance, characterized by swirling, concentric lines that mimic wood grain or natural patterns. The interiors of the bowls are glazed in a vibrant, speckled orange or deep reddish-orange color, which creates a striking contrast with the brown exterior. This speckled effect, reminiscent of a lava glaze or fat lava style, is a common feature in ceramics from the specified period. The dishes are designed to be joined or nested together, with two larger, elongated, and irregularly shaped bowls, and two smaller, perhaps more circular or kidney-shaped bowls. The exact dimensions are not visible, but they appear to be of a size suitable for serving appetizers, nuts, candies, or relishes. There are no visible signs of significant damage like chips or cracks, and the glaze appears to be in good condition, exhibiting a healthy sheen. The craftsmanship suggests studio pottery or a mass-produced item inspired by artisanal trends, with a focus on organic forms and contrasting glazes. The unique interconnected design makes this a distinctive and visually engaging set, typical of the atomic age or brutalist design aesthetics popular during that era.
