Craz"ing (?), p. pr. & vb. n. of Craze, v. Hence: n.
Fine cracks resulting from shrinkage on the surface of glazed pottery, concrete, or other material. The admired crackle in some Oriental potteries and porcelains is crazing produced in a foreseen and regulated way. In common pottery it is often the result of exposure to undue heat, and the beginning of disintegration.
