Forensic glass analysis is the application and analysis of glass to determine details about a crime. Glass evidence comes in many forms in various types of criminal cases. Glass can be analyzed to understand its origin using comparative analysis which may include measurements relating to physical match, refractive index, density and elemental analysi
The interlayer keeps the layers of glass bonded even when broken, and its toughening prevents the glass from breaking up into large sharp pieces. [9] This produces a characteristic "spider web" cracking pattern (radial and concentric cracks) when the impact is not enough to completely pierce the glass. [10]
A conchoidal fracture is a break or fracture of a brittle material that does not follow any natural planes of separation. Mindat.org defines conchoidal fracture as follows: "a fracture with smooth, curved surfaces, typically slightly concave, showing concentric undulations resembling the lines of growth of a shell". [1]
Glass disease, also referred to as sick glass or glass illness, is a degradation process of glass that can result in weeping, crizzling, spalling, cracking and fragmentation. [ 1 ] [ 2 ] Glass disease is caused by an inherent instability in the chemical composition of the original glass formula. [ 3 ]
Breaker-grozier pliers. Breaker-grozier pliers, or groziers, are pliers used by glaziers to break and finish glass in a controlled manner, a technique known as grozing.They are dual purpose pliers, with a flat jaw that is used for breaking out scores and a curved jaw that is used for grozing flares from the edge of broken glass.
Flying glass resulting from an explosion poses a significant risk in the event; up to 85% of injuries from an explosion are due to flying glass. [1] Severity of injury from flying glass depends on the peak overpressure of the blast. [2] Potential for injury has been derived from both experiments and theoretical modeling of blast effects.
Small glass bottles (mostly beer) are broken, one-by-one, inside these deposit refund machines as the bottles are inserted. A large, wheeled hopper (very roughly 1.5 m by 1.5 m by 0.5 m) inside the machine collects the broken glass until it can be emptied by an employee.
Breaking glass is the action of damaging or destroying a glass object. It may also refer to: Arts and media ... Glassing, use of broken glass as a weapon
