Ведьмин котёл

Use case: stylized-concept.
Asset type: one transparent PNG sprite for parallax, orbital motion and gentle edge swaying in an animated video background.
Subject: one squat antique black cast-iron witch cauldron with attached curved handle and three small feet, purple potion surface visible inside the rim, no floating smoke or sparks. Premium tactile realistic three-dimensional studio object photography with subtle natural material detail, soft diffuse upper-left lighting.
Composition: Square canvas; exactly one whole isolated compact object centered, 75 percent of canvas with generous transparent padding on every side.
Constraints: genuinely transparent alpha background with completely empty transparency outside the silhouette and in all gaps. No bokeh, atmospheric haze, background colours, floor, scenery, backdrop, checkerboard, external cast shadow, extra objects, text, logo, border or watermark. Do not create an animation, finished background, sheet or montage.
