These are the three main TYPES of glass ingredients
Glass former, modifier, intermediate
100

These are two of the many properties of Glass:


Various
100

This is likely the type of glass we used in our glass blowing lab


 Soda Lime


100

This recycled product is added to glass.


cullet
100

This is the reason that glass doesn’t turn into a liquid


Amorphous

200

This type of glass is expensive and sparkly:


 Lead Alkali Glass


200

Ceramics have this type of structure:________, while glass has this type of structure: _______


 Crystalline, amorphous


200

The color for the glass bead came from this variable


wire oxide
200

Internal reflection is an important property of glass for this reason… 


fiber optics


200

Glass annealing ovens are called this


lehrs

300

The intermediate is needed for this reason:


Stability
300

Inorganic nonmetallic materials produced from earth materials is a good definition of this word


 Ceramics


300


Emitting light as a result of being heated is called what?



Incandescence

300

Glass plants and manufactures can check their glass for stress and fractures by using this


Polarizing films
300

This is the reason that material is likely to break due to rapid temperature change


 Thermal Shock


400

Glass formers need modifers because of this reason:


 High melting Point


400

This type of bond holds ceramic material together and this type holds glass together


ionic Bonds, covalent bonds


400

The compound formed through an ionic bond during our iron wire demonstration was called what? 

Iron Oxide


400

Glass is strong in __ and weak in ____


 Compression, Tension 


400

We performed two heat treatments in the lab. ___________ makes glass stronger and _____________ removes any cracks and stress in the material


 Tempering, Annealing


500

Because glass either returns to its normal shape or else it breaks, we say that glass is very _________ but not very ___________. (Both of these words rhyme with FANTASTIC!)


Elastic, NOT Plastic


500

Pyrex used to be made out this type of glass, but now is made out of this type of glass


Borosilicate, soda lime


500

One mole of Sodium Carbonate (Na2CO3) weighs this many grams


106 g
500

What is an advantage and a disadvantage of tempered glass?


 Very strong, but cant be drilled or cut without breaking into tiny pieces


500

The amount of expansion per unit length per degree change in Celsius is known as this:


 Coefficient of Thermal Expansion. The lower the coefficient, the less likely it is to break!
