Tempered glass in the context of "Glazing (window)"

A backboard is a piece of basketball equipment. It is a raised vertical board with an attached basket consisting of a net suspended from a hoop. It is made of a flat, rigid piece of, often Plexiglas or tempered glass which also has the properties of safety glass when accidentally shattered. It is usually rectangular as used in NBA, NCAA and international basketball. In recreational environments, a backboard may be oval or a fan-shape, particularly in non-professional games.

The top of the hoop is 10 feet (3.05 m) above the ground. Regulation backboards are 6 feet (1.83 m) wide by 3.5 feet (1.07 m) tall. All basketball rims (hoops) are 18 inches (46 cm) in diameter. The inner rectangle on the backboard is 24 inches (61 cm) wide by 18 inches (46 cm) tall, and helps a shooter determine the proper aim and banking for either a layup or distance shot.

A glass cutter is a tool used to make a shallow score in one surface of a piece of glass (normally a flat one) that is to be broken in two pieces, for example to fit a window. The scoring makes a split in the surface of the glass which encourages the glass to break along the score. This is not to be confused with the tools used to make cut glass objects.

Regular, annealed glass can be broken apart this way but not tempered glass as the latter tends to shatter rather than breaking cleanly into two pieces.

A backboard shattering (also known as backboard breaking or backboard smash) is an accident or stunt in basketball. It occurs when a player performs a slam dunk with sufficient force to shatter or otherwise destroy the tempered glass of the backboard, often causing the hoop to break off as well. Games are usually canceled or delayed and it incurs a foul for the offending player and costs of cleanup and replacement. Shattering a backboard can be dangerous, sending various small pieces of the backboard glass flying, potentially injuring players, sideline press personnel, referees, or spectators. In the National Basketball Association (NBA), shattering a backboard during a game is penalized with a "non-unsportsmanlike" technical foul and a possible fine towards the player. The player may not be ejected, nor shall the foul count towards a player's total towards either ejection or suspension. The referee also has latitude to waive off the foul, if it is determined the shattering was accidental due to a defect in the backboard or its structure, the board was broken during a rebound of the ball from a jump shot, or if the player had no intentions to dunk with force.

Throughout the history of basketball there have always been athletes with the size and strength to slam dunk the ball through the rim. However, the first recorded NBA player to shatter a backboard, Chuck Connors (who would become far more famous as an actor), did not do so with a dunk. When playing for the Boston Celtics in 1946, Connors took a set shot during pregame warmups, hitting the front of the rim. Because an arena worker had failed to place a protective piece between the rim and backboard, the backboard shattered. All-star power forward Gus Johnson of the Baltimore Bullets became famous as a backboard breaker in the NBA, shattering three during his career in the 1960s and early 1970s. In the American Basketball Association (ABA), Charlie Hentz shattered two backboards in the same game on November 6, 1970, resulting in the game being canceled. An invention by Arthur Ehrat to create the breakaway rim with a spring on it led to the return of the dunk in college basketball.

A display case (also called a showcase, display cabinet, shadow box, or vitrine) is a cabinet with one or often more transparent tempered glass (or plastic, normally acrylic for strength) surfaces, used to display objects for viewing. A display case may appear in an exhibition, museum, retail store, restaurant, or house. Often, labels are included with the displayed objects, providing information such as descriptions or prices. In a museum, the displayed cultural artifacts are normally part of the museum's collection, or are part of a temporary exhibition. In retail or a restaurant, the items are normally being offered for sale. A trophy case is used to display sports trophies or other awards.

A computer case, also known as a computer chassis, is the enclosure that contains most of the hardware of a personal computer. The components housed inside the case (such as the CPU, motherboard, memory, mass storage devices, power supply unit and various expansion cards) are referred as the internal hardware, while hardware outside the case (typically cable-linked or plug-and-play devices such as the display, speakers, keyboard, mouse and USB flash drives) are known as peripherals.

Conventional computer cases are fully enclosed, with small holes (mostly in the back panel) that allow ventilation and cutout openings that provide access to plugs/sockets (back) and removable media drive bays (front). The structural frame (chassis) of a case is usually constructed from rigid metals such as steel (often SECC — steel, electrogalvanized, cold-rolled, coil) and aluminium alloy, with hardpoints and through holes for mounting internal hardware, case fans/coolers and for organizing cable management. The external case panels, at least one of which are removable, cover the chassis from the front, sides and top to shield the internal components from physical intrusion and dust collection, and are typically made from painted metallic and/or plastic material, while other materials such as mesh, tempered glass, acrylic, wood and even Lego bricks have appeared in many modern commercial or home-built cases. In recent years, open frame or open air cases that are only partly enclosed (with freer ventilation and thus theoretically better cooling) have become available in the premium gaming PC market.
