Making outline
- Machine and grade baked non-graphitized carbon body into selected carbon electrode rods for earlier furnace startup
- Detailed procedure and acceptance remain unresearched.
What remains unresolved
- Discovery hypothesis only: quantitative demands, full recipe, quantities, losses, compatibility and acceptance remain to be researched.
- Current memory-first method needs source and compatibility review.
Earlier research provenance
