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
Lollipop heated to about 310˚F, the temperature that the solution is heated to is dependent on the specific volume and contents of the mixture. After heating is complete, the solution can then be cooled. The final cooled solution is a supersaturated due to the fact that the moisture content drops to below 2%. Supersaturated or supercooled liquids are also formed due to the fact that crystallization is being inhibited. They are unstable because crystallization is a favored reaction in this case. During the cooling process, the most important physicochemical characteristic of lollipops is occurring. This process is called glass transition. Glass
