The Lab
Built in public
We build in public. The molten oxide, the crystal, the failures and the physics of why this is hard, all shared openly. The recipe stays ours.
Destruction test
Oxide vs. coated silicon-carbide at 1500 °C
Two parts, one oxidising flame. One flakes and fails. Ours glows and holds. The clearest thing we make.
Process film
Growing sapphire fibre in parallel
Thousands of single-crystal filaments pulled at once from one die plate. The start of everything.
Process film
The fibre array, end to end
Molten alumina at the tips, a curtain of fibre descending in vacuum, gathered cold into cloth. Automation as craft.
Notebook
The manufacturing trilemma
Why making this material strong, to final shape and to tolerance all at once is the real problem, worked in public.

New films and notes ship most weeks. Generous with wonder, guarded with the recipe.
