A TRIAL INDEX OF LAMINAL DISRUPTION1

George L. Stout


ABSTRACT—A scheme for describing this kind of degradation is suggested. Laminal disruption is a defect of a film, a thin cutting, or a coating which is an integral part of an artifact—paint, lacquer, marquetry, and enamel are examples. Disruption may lie parallel to the surface plane or contour: cleavage; it may run perpendicular to the surface: fissurage. Cleavage takes one of two general forms—shell clefts and ridge clefts. Fissurage also follows one of two types—rifts and crevices. The varied patterns that occur within these types can be described by terms that relate to the facts of their appearance.
