Making outline
- Reduce prepared tungsten oxide with dry hydrogen in controlled powder furnace, collect and classify metallic tungsten powder
- Detailed procedure and acceptance remain unresearched.
What remains unresolved
- Manufacture, quantities, suitability and complete inventory remain unreviewed.
- Current memory-first method needs source and compatibility review.
Canonical reuse assessment
"Distinct reduced-metal state, not oxide or finished tool."
