Deconstruct the commodity into 3 Educational Assets:
     The Core :  Identify the most common or valuable raw form.
         (e.g., Spices -> A pile of Black Peppercorns. Tea -> A mound of Black Tea leaves. Gold -> A large Nugget). 
     The Varieties:  Identify 4-5 distinct variations or colors.
         (e.g., Spices -> Red Paprika, Yellow Turmeric, Brown Cinnamon. Tea -> Green, White, Oolong, Matcha).

Goal: "Commodity Universe" Educational Diorama.
     The Base:  A large, square   Polished Walnut or Oak Board   sitting on a library table.
     The Layout:  A radial/circular design in the center, flanked by narrative vignettes in the corners.

  3. The Centerpiece
     The Metaphor:  The commodity is the center of the world.
     The Sun:  A massive, textured pile of the "Core" material (Step 1) sits in the exact center.
     The Orbit:  Inlaid gold or brass rings ripple out from the center.
     The Planets:  Smaller mounds or spheres of the "Varieties" (Step 1) orbit the center, creating a colorful spectrum of textures (powders, grains, solids).

  4. Narrative Corners 
     The Origin (Top Corners):  Miniature dioramas sculpted directly onto the board showing the harvesting process (e.g., tiny figures picking tea leaves, mining gold, or shaking spice trees).
     The Journey (Bottom Corners):  Miniature dioramas showing the "Transit" (Step 1).
         Detail:  Use   Resin   for water (ships) or   Sand   for deserts (camels).

  5. The Footer:  
     Placement:  Along the bottom edge of the board.
     Format:  Three or four rectangular   Wooden Plaques   embedded in the table.
     Content:  The name of a specific variety (e.g., "Cinnamon") engraved in serif text, with a physical sample of that ingredient piled on the plaque.
