Octagonal Blue and White Floral Porcelain Plate

This is an octagonal porcelain plate, likely serving as a side dish or decorative piece, featuring a prominent blue and white design. The overall shape is an eight-sided polygon with slightly curved edges, lending a subtle elegance to its form. The rim of the plate is defined by a thin, reddish-brown or rust-colored line, providing a warm contrast to the cooler tones of the main design. The central well of the plate is adorned with a detailed depiction of what appears to be white flowers with delicate leaves and stems, set against a rich, mottled blue background. This background design evokes the appearance of a cloudy sky or perhaps a turbulent water scene, with varying shades of blue creating depth and movement. The white floral motifs stand out sharply against this deep blue, suggesting a high degree of contrast in the glaze application. The porcelain material itself appears to be a light cream or off-white color where not decorated, indicating a fine, perhaps translucent ceramic body. There are no obvious chips, cracks, or significant wear visible from the provided image, suggesting good preservation. The craftsmanship seems precise, particularly in the detailed floral work and the clean lines of the octagonal shape. The style strongly suggests an East Asian origin, possibly Japanese Arita ware or Chinese export porcelain, generally dating from the mid-20th century or earlier due to its style and typical manufacturing practices, though without a maker's mark, precise dating is challenging. The pattern is hand-painted or meticulously transfer-printed, and its aesthetic quality suggests it was intended for table use or as a decorative accent.
