Superconductor Sphere — Copper Niobium Desk Fidget Ball

A sphere turned from genuine superconductor billet, so the niobium filament bundle reads as a copper honeycomb wrapping the whole ball.

There is no way to reproduce this pattern by machining or plating — it is the internal structure of the material, exposed.

Details

• Material: Superconductor, Mokume Gane
• Quantity: 1 piece / 2 pieces
• Made to order: forged after you order, ships in 1–2 weeks

Engraving

Included, not charged as an extra. Add your text on this page before you add to cart and we will cut it on the face. A proof comes back to you before anything is marked.

Care

Wipe with a dry cloth. Polish the copper to brighten it, or leave it alone and let it go dark — both are correct.

Forged individually after you order, so the figure on yours will not match the photograph exactly — that is the nature of the process, not a defect. Free shipping worldwide.

• Superconductor
• Copper

Hand-forged and finished in the workshop. Every metal ages differently — Damascus steel wants an occasional wipe and a drop of oil, titanium asks for nothing at all. How to care for each metal

Every piece is forged to order, so allow 1–2 weeks in the workshop before it ships. Engraving can add a day or two.
