crazing

1. Fine cracks in an adhesive which may extend in a network on or under the surface or through a layer. It is caused by excessive shrinkage characteristics of the adhesive film, too rapid drying of the adhesive, or by flexing of a brittle adhesive. 2. The process by which yellow or transparent parchments often become whiter and more opaque when folded, producing irregular and disfiguring effects at the joints of vellum bindings. (291 , 309 )
