The benefit of this differential heating comes in the form of increased endurance of the glass it means that such glass can be stretched or pulled to a certain limit without breaking, which is a good thing to have in many forms of glass. The compressive stress gives toughened glass its increased strength the higher the stress, the smaller pieces that the glass breaks into. Glass (with nickel sulphide inclusions) is tempered by heating and then rapidly cooled to room temperature.Ĭooling takes place much faster at the center of the glass than at the surface, causing compressive stresses in the surface, whereas contraction and tensile stresses are caused in the center. The way that tempered glass breaks into much smaller pieces is specifically attributed to the manufacturing processes. The glass does not shatter out of the frame instead, it converts into tiny granular pieces and remains intactĪs mentioned earlier, the characteristics of any glass type depend on the materials it is made with and the chemical and mechanical processes it undergoes during its manufacture.

GAMES & QUIZZES THESAURUS WORD OF THE DAY FEATURES SHOP Buying Guide M-W Books. to cause to drop or be dispersed to break at once into pieces to damage badly : ruin See the full definition.
During any such scene, have you noticed that the glass in car windows doesn’t break like regular glass (that we use in our daily lives)? Instead, it breaks up into very tiny, granular pieces. The meaning of SHATTER is to cause to drop or be dispersed. You have surely seen movie scenes where automobiles (like cars or trucks) blow up or get smashed against something. However, strength is not the only thing that varies depending on how the glass is made there’s another rather unusual trait that separates certain glass types from others – the way the glass breaks. Aim for a loud volume a pure resonant pitch. Simply flick the bulb of the glass gently with your fingernail, listen carefully to the resulting tone, and tweak your pitch to match it. It is a terrific and highly useful material – transparent, reflective and reasonably strong (depending on the type of glass). Check your pitch frequently as you attempt to shatter the glass with your voice. It is also manufactured in a way that causes it to break into smaller pieces, which is safer than regular glass shattering into large shards.įrom coffee tables and skyscrapers to house windows and car windshields, we are surrounded by glass. The story of a young journalist who fell from grace when it was discovered he fabricated over half of his articles from the publication The New Republic magazine. It is believed that if you broke a glass intentionally, it is. With Hayden Christensen, Peter Sarsgaard, Chlo Sevigny, Rosario Dawson.
Tempered glass is stronger than regular glass and can withstand higher temperatures. Depending upon the situation, the broken glass may symbolize damaged things and vanish for good. How laminated glass is different from other glasses?.Why does tempered glass break into tiny pieces?.
