Layered Gray Shale



These stones were at one point directly connected to the Latneuses, usually being present in the backside of Latneuses stones. The “hybrid” nomenclature was given to them in the past and I don’t know the reason. This layer of stone is composed of mostly crystalline quartz instead of spessartine and feels like it withstood slightly higher grade metamorphosis.

This whetstone feels hard, glassy, does not have the same versatility and is hardly suitable for sharpening. However, it is still a decent honing stone.These stones were found at one of the mines around Vielsalm. They were the only specimens found so there’s no way to know if they come from the mine or even the region. They could have been brought from somewhere else, like the Brazilian Shale that was also found at the same place.

Mediocre stones for sharpening and honing, and unsuitable for polishing. They looked interesting which is why I decided to bring them with me.
