31. These discontinuities allow detection of the glass transition temperature where a supercooled liquid transforms to a glass. 32. Crystalline polymers ( especially those reinforced with fillers ) can be used even above their glass transition temperature. 33. Honey has a glass transition between. 34. Upon cooling through the glass transition , the welded piece will solidify as one solid piece of amorphous material. 35. But the glass transition is different. 36. Typically, if T _ r is set to match the glass transition temperature T _ g, we get 37. These discontinuities are frequently used to detect the glass transition temperature where a supercooled liquid transforms to a glass. 38. "We've been remarkably unsuccessful in coming up with a theory of the nature of glass and the glass transition ," 39. While a glass transition occurs when the liquid state is cooled, the jamming transition happens when density is increased. 40. Unlike metals, which have a specific melting point, glasses and plastics have a melting range, called the glass transition .
