Fragment of a Darkened Brick or Ceramic Block

The item appears to be a fragment of a brick or similar ceramic building material, characterized by its dark, almost black, exterior surface and a contrasting reddish-brown interior visible on one of the broken edges. It has an irregular, roughly rectangular or block-like shape, suggesting it is a piece broken off a larger object. The top surface exhibits a slightly concave or trough-like depression, which could be natural wear, part of its original design, or a result of how it fractured. The dimensions are not provided, but based on the image, it seems relatively small, possibly fitting in the palm of a hand. The visible surfaces are coarse and unrefined, consistent with a utilitarian object rather than a decorative one. The dark coloration suggests exposure to heat or fire, possibly indicating it was part of a kiln, hearth lining, or suffered a fire event. There are no discernible markings, stamps, or specific maker's marks visible. The edges are rough and jagged from breakage, and there's a general appearance of age and outdoor exposure, evidenced by some surface erosion and dirt. Its condition suggests significant wear from use or environmental factors. Given its appearance, it likely dates from a period when such materials were commonly produced for construction, potentially from the 19th or early 20th century, though dating is difficult without further context or analysis.
