Obsidian Lacework

A closer look

A round suspended lattice of black glass opens around the sun between pale stone columns.

Give the dark material breathing room

Obsidian is real volcanic glass; the immense self-supporting network in the reviewed image is an AOI material fiction, not a practical glassmaking technique. Its strength as an image comes from absence. Large holes expose the pale sky while the remaining black ribs branch into smaller perforations. At a distance the sculpture reads as a single round silhouette; near it, the threadlike edges invite inspection.

Design the largest openings first, then connect them with a few thicker structural paths. Only after those are clear should finer webbing spread into the gaps. Let some edges catch warm points of light, but keep most of the glass dark. Uniform sparkle would erase its silhouette and turn the piece into jewelry rather than an airy spatial structure.

Use light to explain the void

Backlighting is essential because black-on-black detail disappears. A quiet stone setting and open horizon let the viewer see through the lattice. For a new composition, specify the outer silhouette, the number of major voids and the sun's position. Review both the whole object and one junction: the first must remain coherent, the second should still look glassy and edged rather than like woven rope.
