Here's a little information that should help you cazz. Especially after your false claims of looking under the Lindi bonnet.

Strong. 50 - 100 MPa.
Specimen requires more than one blow of a geological hammer to fracture it.
(Limestone, marble, phyllite, sandstone, schist, shale.)

Medium strong. 25 - 50 MPa.
Cannot be scraped or peeled with a pocket
knife, specimen can be fractured with a single blow from a geological hammer.
(Claystone, coal, concrete, schist, shale, siltstone.)

Weak. 5 - 25 MPa.
Can be peeled with a pocket knife with
difficulty, shallow indentation made by
firm blow with point of a geological hammer.
(Chalk, rocksalt, potash.)

So once again cazz the DFS expert, what are the MPa ratings of Lindi's Weathered and Fresh Materials? DYOR.
