We were walking up the tops of Northowram the other day, up past were all the old stone quarries used to be, and I suddenly spotted an abandoned pile of stone slates. Somebody had kindly chiselled numbers on each of them so they turned into a traditional stone equivalent of my daily calendar I was thrilled with this authentic historical discovery, and as someone had equally carved the name of the quarry on each stone, I headed home to see if I could pin down their origin to perhaps Northowram or the Shibden Valley. Oh, Burnett, Burnett, Burnett .... you gullible fool. A quick quarry of the internet revealed their origin. They are "reconstructed stone" made from glue and stone dust. They have been "authentically recreated" to even incorporate tool marks. You can even buy a version with fake green lichen clinging to them. They come from a factory somewhere down south. They are the stone equivalent of MDF. They are as genuine as a politicians promise to support NHS workers.
