Does anyone with both stones share the same idea that this may be true? This evening I was playing with a new routine of mine and I decided to try to finish on my Dark BLue Escher with just water. It was no where near as fine at my little Thuringian in the box with just water (It's a light grey and not dark like the blue).
I may have to start having a progressive finish routine with the stages of Escher colors at the end!
