Heat Strengthened Glass Breakage Pattern [ Top-Rated • Tutorial ]

Architects leverage the specific breakage behavior of HS glass for targeted building applications.

Often laminated so the large fragments provide structural residual capacity if broken. heat strengthened glass breakage pattern

While nickel sulfide (NiS) inclusions are rare in HS glass due to lower tension levels, any spontaneous failure will show a characteristic "butterfly" or figure-eight pattern at the origin. Comparison of Glass Breakage Patterns Glass Type Surface Compression Breakage Pattern Fallout Risk None (< 1,500 psi) Very large, sharp shards High fallout Heat-Strengthened 3,500 to 7,500 psi Large, radial fragments Low (remains framed) Fully Tempered > 10,000 psi Tiny, blunt geometric cubes High (clumps fallout) Applications Dictated by Breakage Behavior Architects leverage the specific breakage behavior of HS
