Thread: Help! Identifying Turkish Natural Stone

Hello everyone, I live in Turkey and my friend gave me this natural stone yesterday but I haven't used it nor lapped it. This stone was mined northern-east region near the Georgia and the Black Sea. A sixty-five years old man mines this stone from his village area. He confirmed that this type of stone used to be used as a razor hone or other tools. My friend tried to hone his razor and said it is not finer than his coticule and shave was like a coticule. Making slurry with this stone is not easy. By the way stone is drying very fast. Like my Chinese 12k(PHIG). Surface of the stone is very very smooth glass like(by feel). Couple of experienced friends claim that this stone somehow alike Thuringian stones. Any thoughts?
