Q

A glass without internal stresses caused by heat treatment. It is heated above a transition point and then allowed to cool slowly without being quenched.

4-6 times stronger than annealed glass.

Annealed glass breaks into large, jagged shards that can cause serious injury.

Q

A type of glass that has increased strength. The glass is chemically strengthened by submerging the glass in a bath containing potassium salt at 450 C.

6-8 times the strength of annealed glass.

May be cut after strengthening unlike toughened glass or temperature glass.

Q

Glass having an irregular surface pattern formed in the rolling process to obscure vision or to diffuse light.

A

Patterned Glass

18
Q

A transparent sheet of glass that is turned opaque through sandblasting or acid etching.

A

Frosted Glass (by sandblasting or etching)

19
Q

Refers either to the material or colored glass or to the art and craft working with it. Stained Glass is colored using metallic salts during its manufacturing process.

A

Stained Glass

20
Q

A transparent, hollow block of glass with clear, textured or patterned faces by fusing two halves together with partial inside and used for glazing openings.

Good for sound-proofing.

3” thickness.

A

Glass Block / Glass Brick

21
Q

A glazing system in which sheets of tempered glass are suspended from special clamps, stabilized by perpendicular stiffeners of tempered glass, and joined by a structural silicone sealant or by metal patch plates.

A

Curtain Wall System

22
Q

This type of glass helps maintain room temperature.

However, this glass has been blamed for damage to adjacent buildings and parked vehicles due to the amount of heat that it reflects back.

A

Low-E Glass

23
Q

A glass having one or both sides acid-etched or sandblasted to obscure vision.

A

Obscure Glass

24
Q

For reflective glass, what will you see at around 8 pm when you are inside and the lights are on?

A

In summary, it is always possible to see through one side of reflective window film; which side is entirely dependent on the light. If it’s brighter outside, then you will be able to see through the film from the inside out.
