Poster Mangkuk Celadon dan Cincin Pembakaran

A 4:5 vertical contemporary ceramics promotional poster photographed from a direct overhead perspective. In the center sits an irregular, hand-thrown celadon tea bowl with a slightly elliptical rim, natural glaze gradient transitioning from gray-cyan to moon-white, and a delicate iron-brown edge. Visible glaze depth, micro-bubbles, and subtle artisanal wheel marks are present. Surrounding the bowl are six concentric circular material bands depicting kiln firing progression: the innermost ring is wet dark clay, followed outward by semi-dry mud, bisque ware, initial melt glaze, a green vitrified layer, and an outermost ivory-white glaze with fine crackle. Each band has tactile thickness, authentic grain, and firing variations; delicate crackle lines extend inward from the outer rim without crossing the central bowl. Typography and graphics: The text "[KILN]" is set along the left curved arc in a restrained, high-contrast serif font. The lower right corner displays "[CELADON / 1280°C]". In the upper right corner, a clean rectangular glaze swatch illustrates a three-stage transition from gray-cyan to moon-white without explanatory arrows. Lighting and aesthetic: Soft, directional light from a large overhead softbox at the upper left highlights the ridge depth of the concentric rings, micro-reflections in the glaze, and the cast shadow of the bowl. Studio museum photography meets scientific material experiment layout, with a solid, opaque rectangular background filling the frame.
