This limestone is from the Dinantian epoch of the Lower Carboniferous. It was laid down approximately 350 million years ago in semi tropical seas. It is made up from the calcium rich shells, bones & skeletons of the fauna that was prevalent at that time. The Derbyshire limestone is very pure, about 98% soluble in rainwater (over time) leaving only residual clay. This product is supplied in lots of 1 kilos and comes in a polythene bag with a label.
