Ceramic Dish with Blue Underglaze Mark (not authenticated)

This ceramic dish features a speckled, textured white and grey exterior glaze reminiscent of granite or rough stone, contrasting with a smoother off-white interior glaze that displays mottled yellowish-brown discoloration and crazing. The piece is oval in shape with an irregular, organic rim profile, suggesting a hand-formed or studio pottery origin. On the interior base, there is a visible blue underglaze mark or signature written in a cursive, possibly Asian script or stylized monogram. The physical condition exhibits signs of age and prior use, including staining and surface wear within the well of the dish. There is no visible factory stamp or production serial number, and the attribution relies entirely on the handwritten blue mark observed on the base. The style is consistent with mid-century or contemporary studio ceramics, though without physical inspection or provenance, the age and maker remain unverified. The owner provided the note 'Used', which is unverified context. Quality indicators include the tactile, textured body and distinct glazing techniques typical of artisan-crafted earthenware or stoneware vessels.

Based on the visual evidence available in the photograph, I have evaluated this studio pottery ceramic dish featuring a textured white and grey exterior glaze and a blue underglaze cursive mark on the interior base. Per user submission, the item is described as 'Used'. Based on what I can see, the piece displays characteristic features of mid-century or contemporary artisan ceramics, including an organic rim profile, mottled interior discoloration, and visible crazing within the well. However, I cannot verify the age, exact studio origin, or maker from a photo alone, and the blue cursive mark must be treated strictly as a working assumption rather than a confirmed signature. The estimated value range of $150 to $300 assumes the hypothetical scenario that the attribution is correct and the mark corresponds to the intended maker. General market demand for contemporary and mid-century studio pottery remains steady among collectors who appreciate artisan craftsmanship, though unauthenticated pieces of this type typically sell for significantly less. If physical inspection reveals the piece to be a later reproduction, a replica, or merely 'in the style of' a studio potter rather than an autograph work, the market value would likely drop to the $30-$75 range. To establish authenticity and refine this estimate, one would need a physical inspection by a ceramics expert, detailed hallmark or signature verification, and research into provenance documentation.
