3. Construction Glass
Components: -Silica
-Lime
-Sodium Oxide
- & Small amounts of magnesia & alumina
Soda-lime-silica
(window glass)

4. Basic Glass Specialty Glass
 Sheet Glass  Laminated Glass
 Polished Plate Glass  Wire Glass/Wired Glass
 Tempered Glass  Patterned Glass
 Float Glass  Frosted Glass/Obscure
Glass
 Low-Emissivity Glass

5. Ways to Identify…
Thickness
3/32” (2.16-2.57 mm): Single Strength glass is used in small windows
and picture frames
1/8” (4.32-5.14 mm): Double Strength is used in windows and larger
picture frames
3/16” and ¼”: Plate is used for large windows, shelves, table tops
3/8”, ½”, and ¾”: Used for larger table tops and shelves

6. Production vs. Recycle
 1,300 pounds of sand  requires 32% less energy
 400 pounds of soda ash  requires 50% less water
 400 pounds of limestone  creates 20% less air pollution
 151 pounds of feldspar  saves 10 gallons of oil
 24,000 gallons of water  saves 1.2 tons of raw materials
 15 million BTUs of energy  this mix melts at 2,500 degrees
Fahrenheit
 this mix melts at 2,800 degrees
Fahrenheit.
Keep in mind, REUSE requires none of these factors

7. Uses of Recycled Glass
 Fiber Glass
 Glass Wool Mat, Blanket, or Board
 Construction
 Pipe Cover
 Thermal Insulation Board
 Ceiling Board
 Acoustical Insulation Board
 Cement Replacement
 Ceramic Tiles
 Paving Blocks
 Added to Asphalt
 Ashcrete**

8. Where???
 Glass shops
 Used construction materials or
salvage businesses, such as Resale
Lumber
 Penny-saver newspapers (Tri-City)
 Remodeling sites and remodeling
businesses
 Demolition sites
 Yard sales and giveaways

9. Scoring and Breaking Glass
1. Clean the surface of the glass
2. Score the glass. Aim for a uniform score with
consistent pressure.
3. Break the glass after scoring
Tools Needed:
- Glass cutter
- Oil
- Glass pliers

- Putty knife, points, single-edged razors

10. Glass Trivia
 Glass takes 1,000,000 years to
decompose.
 Glass never wears out-it can be
recycled forever.
 Glass recycling saves resources-each
ton of recycled glass replaces 1.2 tons
of raw material (sand, limestone and
soda ash).
 The energy saved from recycling 1 glass
bottle can run a 100-watt bulb for 4
hours.
 Only 27% of the glass used in the United
States is recycled.
 When glass breaks, the cracks move at
speeds of up to 3,000 miles per hour.
