Making outline

Condition selected water/clay-bearing mineral powder and mechanically compact annulus using independently made die/mandrel/ejector and earlier manually powered press, then support and shelter drying
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.
