Rouge du Salm, Soft

Name: Rouge du Salm, Soft
Provenance: Regné, BE
Geology: Low-grade metamorphic stone
Composition: Clay, spessartine, quartz
Use case: Polishing

Grit size: 5k-7k
Hardness: 2.5/5
Cutting speed: 3/5
Feedback: 4.5/5This stone is also found at the Ol Preu quarry. However, no interest was ever shown towards it, since the stones mined there were meant to be used for sharpening and honing, not polishing. Coming from the upper layer, it was subject to less pressure (and time), which means it is a softer stone that wears out faster and produces a lot more slurry. These characteristics can be a detriment in some cases. But for smooth and visually striking polishing, they are fundamental. 


This stone gave me the best polishing results so far. Not perfectly smooth but also not far from it, and with very nice contrast between layers.
