Boston Stone, The
n Originally a paint mill imported around 1700 by a painter, Thomas Child. Later used as a landmark or central point from which distances from Boston were measured. It is the earliest known implement of the paint industry in America. The round stone was rolled back and forth in the trough of a larger flat stone underneath, in which oil and pigment were dispersed. The Boston Stone is the official insignia of the Federation of Societies for Coatings Technology. (Paint/coatings dictionary (1978). Federation of Societies for Coatings Technology, Philadelphia).
