Crazing is the phenomenon that produces a network of fine cracks on the surface of a material, for example in a glaze layer. Crazing frequently precedes fracture in some glassy thermoplastic polymers.razing occurs in some thermoplastics such as acrylonitrile butadiene styrene (ABS plastic) when stressed. It is a typical response in rubber toughening, where crazes are initiated at the surfaces of the rubber particles added to toughen the material.
Crazing on lenses. I have had conflicting answers to my question on why we see now and again a patient with lenses that have horrible crazing marks on the lenses, like what you would see on very old pottery.ince then many manufacturers have made really thin lenses that flex in the edger or in the frames with large A to B ratios. The powerpoint on Tharcles is pretty much what any edger manufacturer will recommend: Reduce chuck pressure Use proper cushioning pads Use proper base chucks etc.
