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.
Eye floaters and flashes are caused by changes in the vitreous gel that occur as we get older. Eye floaters occur when the vitreous gel thickens or shrinks due to aging, causing particles to form in the gel. These particles block the light passing through your eye, casting shadows on the retina. The shadows are seen as floaters, which can be created by: The formation of protein clumps in the vitreous gel. These types of eye floaters tend to look like squiggles, cobwebs, tadpoles, or circles.
