Architectural glass light in industrial factories. Annealed glass is glass without internal stresses caused by heat treatment, i.e., rapid cooling, or by toughening or heat strengthening. Glass becomes annealed if it is heated above a transition point then allowed to cool slowly, without being quenched. Float glass is annealed during the process of manufacture. However, most toughened glass is made from float glass that has been specially heat-treated. Annealed glass breaks into large, jagged shards that can cause serious injury and is considered a hazard in architectural applications. Building codes in many parts of the world restrict the use of annealed glass
Death by burning of death resulting from exposure to extreme heat are known. For example, pouring substances such as molten metal onto a person (or down their throat or into their ears), as well as enclosing persons within, or attaching them to, metal contraptions subsequently heated. Immersion in a heated liquid as a form of execution is considered distinct from death by burning, and classified as death by boiling. The 18th century BC law code promulgated by Babylonian king Hammurabi specifies several crimes in which death by burning was thought appropriate. Looters of houses on fire could be cast into the flames, and
