Thread: Another odd sized stone

this is why i love this forum we all want to know more about the same thing a think tank for razors and rocks. i found alot of info on wikipedia look up shale and look up slate they are both made of all most the same material i think its through the end process that make the stones different ,compaction,heat ect. ok just found this from wikipedia "Shales that are subject to heat and pressure of metamorphism alter into a hard, fissile, metamorphic rock known as slate. With continued increase in metamorphic grade the sequence is phyllite, then schist and finally to gneiss." ok same stuff but the end process makes it into a different preforming rock. like translucent ark and a cf . we did get off track with the true question what is a thuringian made of i think its some sort of fossilized clay with different minerals in it i dont think it has shale in it but i could be wrong the quest continues.

Ok after all that was said i found two source's one from timbertools and one from the srp wiki i'll quote the srp wiki "The stones made by the Escher & Sohn company, produced from 1709 to the early 20th century in Germany, have gained an almost legendary status among razor honers. So much so that they, like Kleenex or Coca Cola, have become the name applied to a whole genre of their type, these days simply referred to as Thuringian. Mined in the Thuringia area of central Germany, these metamorphic stones are composed of an abrasive quartz embedded in chalk" i would like to know srp sources for this info. i guess that will have to do for now .

Yeah we really wandered pretty far off topic with this thread. lol. Oh well, I stand my my original thought that the OP will have to make his best judgement decision. On another note, I've got a name this hone thread coming in about 3 minutes. lol.
