"Fully tempered glass is used in many applications because of its safety characteristics. Safety comes from strength and from a unique **fracture pattern**. Strength, which effectively resists wind pressure and impact, provides safety in many applications. When fully tempered glass breaks the glass fractures into small, relatively harmless fragments. This phenomenon called "dicing," markedly reduces the likelihood of injury to people as there are no jagged edges or sharp shards."

"Fracture structure" sounds a bit odd ;-)
