Use case: logo-brand. A sophisticated sculptural brand-mark study for Dingwei, GRAYSCALE ONLY, one standalone mark centered on a very light neutral gray background, landscape1536x1024. Not text, not a product photo of a pot. Reimagine the structural idea of an ancient Chinese ding pictograph as a contemporary open sculptural relief: a generous vertically oval hollow center, two shoulders which rise and curl gently inward but do not meet, a substantial curved lower belly flowing into three short subtly tapering supports. Overall mark height slightly greater than width, neither squat nor elongated vase. Most important: true modeled volume and variable cross-section, NOT a uniform extruded outline. Each shoulder begins as a fine tapered edge, expands through the side into a fuller folded plane, gathers into a denser belly. The inner surfaces turn continuously into outer surfaces, distinct concave and convex areas visible through soft gray tonal changes. Dry matte graphite-colored mineral material with extraordinarily fine directional striations: they follow the curved flow, gather at the turn and dissipate across broad quiet faces. Texture belongs to the material, no cloth added, no glued textures. Light from broad upper left creates quiet midtone transitions and soft inner occlusion; only a delicate contact shadow. Refined tactile dignity, airy internal space, weight carried low without heavy blocky feet. Some barely perceptible asymmetry of surface flow but balanced overall silhouette. Crisp contour, no outlines drawn on top. Avoid metal chrome, glass, wet sheen, plastic, puffy tubes, jewelry, bronze patina, antique decoration, horns, trophy handles, round badge, animal face, typography, text, frame, strong dark vignette. Entire background bright and evenly lit edge to edge. Large mark occupies central 65% of image height, plenty of white breathing room.

Edit the supplied sculptural mark into a second GRAYSCALE material study, keeping its recognizable open oval center, two tapering shoulders, belly and three integrated supports. Preserve the overall identity and front-facing composition. Replace coarse heavy dark stone with lighter medium-gray unglazed porcelain / densely pressed fine mineral powder: dry silky micrograin, no glossy glaze, no plastic. Reduce the physical front-to-back depth to a shallow sculptural relief rather than a freestanding heavy statue. The broad belly should become a gently folded surface: a clear but soft plane transition follows the inner curve upward into the two shoulders, creating movement from broad quiet lower volume to delicate upper tips. Surface striations must be very fine directional lines, visible only near the bend and fading naturally elsewhere, not noisy scratches covering everything. Slim the three supports modestly and integrate them seamlessly, do not make cartoon feet. Keep substantial belly but make the inner edge more delicate. Large broad upper-left light, restrained shadow in concavity, no shiny rim. Light neutral-gray background edge to edge, no dark corners, no drop-shadow outline, no lettering, no cloth, no other objects. We want depth legible in midtones, not a black silhouette and not a product shot of a vase. Landscape1536x1024.

Precisely edit this grayscale mark. Preserve its silhouette, open center, proportions, three supports, orientation and light direction. Change ONLY surface treatment and local light contrast: remove 90 percent of the coarse stone scratches and granular pitting across the object. Most broad faces should be silky dry satin matte, like very finely honed unglazed porcelain, not glossy. Retain a whisper of fine directional hairline texture ONLY in a narrow region following the inner lower-left bend, fading gently out before it reaches the shoulders or center belly. Soften the bright narrow rim along the right inside curve into a broad gentle midtone transition. No gleaming outlined edge. Keep concave-versus-convex depth legible, material medium-light gray, pure grayscale background. Do not flatten to silhouette, do not add cloth, do not blur contour or replace geometry.
