Thread: Escher stones with streaks and dots

Again a thread for lovers of thuringian stones.
The following pictures show special sized stones from the estate of former JGES company in Thuringia.





Stones with streaks, bands and dots that are visible especially in border layers at the changeover from one colored layer to another color or at the outer layers next to layers that are unuseable for honing ( so called “Knuperschicht” in german, don’t think there is a reasonable translation to American language).




The bands and streaks are simply colors in the homogenes material (caused by trace elements). There are no particles with different size or hardness and this streaks don’t effect honing.




Other than the streaks there are sometimes dots in the stones consisting mainly of iron oxide. These are often larger particles of different hardness which can effect honing a lot, they can even destroy an edged of a straight razor.
