Crazing \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.
