Metalworking stone shield slabs

Selected retained rigid stone slabs with fracture/spall and hazard coverage tests; discovery hypothesis, suitability and quantitative demands unknown.

Discovered · unresearchedClosure: OpenInventory incomplete

Capability requirements and tolerances

Consumer-specific numerical targets, quantities and acceptance limits remain open or incompletely reviewed. No smartphone-grade suitability is claimed. Distinct capability tiers require their own making route and qualification.

Making outline

Select naturally slabby robust tool-stone, split or abrade broad retained shielding panels, reject cracks and retain extra destructive impact/heat witnesses; dimensions, thermal spall and containment grade unknown
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.
