Stoneware-style mug in light blue reactive glaze

This item appears to be a ceramic mug or wide-mouthed cup, possibly for soup or coffee, featuring a rounded body and a geometric, squared handle. The exterior and interior are finished with a variegated light blue or celadon-toned glaze that is stylistically consistent with reactive glazes common in late 20th-century or contemporary stoneware. The rim and the edges of the handle exhibit a thin, brownish-rust glaze detail, often referred to as 'breaking,' where the glaze thins over the sharp edges to reveal a darker color beneath. The bowl of the mug is relatively wide and shallow compared to standard cylindrical coffee mugs. While no maker's marks or stamps are visible in this view, the aesthetic and heavy-walled construction are consistent with brands like Denby or mid-century studio pottery, though no specific attribution can be made without inspection of the base. The surface appears to be in good used condition with a reflective glossy finish and no immediately apparent cracks or large chips visible from this angle. The piece reflects a modern, rustic aesthetic that prioritizes tactile form over intricate surface decoration.

Based on my visual analysis of the provided image, I have examined this wide-mouthed ceramic vessel which appears to be a contemporary or late 20th-century stoneware mug. The piece features a light blue reactive glaze with characteristic 'breaking' along the rim and handle edges, revealing a darker underglaze or clay body. I cannot verify the manufacturer or designer from a photo alone as no maker's marks are visible; however, the aesthetic is consistent with hypotheses of brands such as Denby or various mid-century modern-inspired studio potteries. My valuation is based on the assumption that this is a well-crafted production piece in good used condition. From what I can see, the glaze remains glossy and the piece lacks major structural defects, though I cannot confirm the absence of hairline cracks or underside wear without a physical inspection. The market for rustic, tactile stoneware remains stable due to its functionality and timeless aesthetic. To confirm a more specific attribution, I would need to examine the base for stamps or signatures and verify the weight and density. Should this piece bear a mark by a highly sought-after studio potter, the value could increase significantly; conversely, if it is a mass-produced modern reproduction from a generic housewares retailer, the value would likely fall at the lower end of the $5-$10 range. This estimate assumes the item is an unattributed but quality stoneware piece as suggested by its construction.
