Thread: The Celebrated "Water of Ayr Stone" dark blue or violet

It turns out that you can find treasure in your own cellar

If you do not count the larger stone lying in the upper left corner, the rest of them spent the last 25-30 years in the basement of my apartment.
They were brought home by my dad with two Dalmore Blue stones, which I showed here on the forum earlier.
Before they got to the basement these stones were used in the rotary printing process to sharpen the knives that collected the paint.

Only the oblong stone [in the left-hand corner of the first picture] was used for sharpening chisels over the years.

The largest one, the one on the right, has dimensions 210x125x70mm and weighs 5kg
