That depends on how the glass is fabricated and finished and the environment it is in, and the type of glass. In general, and approximately,
For perfect glass fibers, strength is 500,000 psi (3500 MPa).
For polished glass windows, in air, strength is 7000psi (50MPa)
For scratched glass, 100 micron deep scratch, it is 2500 psi (20 MPa)
For scratched glass in high humidity for several years it is 1000 psi ( 7 Mpa)

Why fracture strength is always greater than yield strength?
The material has to stretch (strain) first before it breaks. For ductile materials, when stretch reaches a certain point it permanently deforms (yield) and continues to carry load until it then breaks as load increases. For brittle materials like glass which do not permanently deform thay simply break without yield.
What is yield strength and tensile strength of 20c8 cast steel?
YIELD STRENGTH 242 N/sqmm TENSILE STRENGTH 440~520 N/sqmm
What is the yield strength of plywood?
Yield strength - 13.8 MPa Ultimate tensile strength - 31 MPa
What is the shear strength of quartz?
The strength of quartz depends on the flaw size. Typically the strength of quartz is about 8000 psi (55MPa) in tension. If severely flawed it could be as slow as half that value, and if it is stressed in water it could be even lower. If perfect without flaws it will exceed 40,000 psi (275 MPa). I would use about 6000 psi in general and use a large safety factor. Most codes use a safety factor of 5 for glass to be certain in case there are hidden flaws. In shear I would use the tension value
Which material provide tensile strength and compressional strength to bone?
the collagen fibers of bone have great tensile strength(the strength to endure stretching forces), while the calcium salts, which are similar in physical properties to marble, have great compressional strength (the strength to endure squeezing forces)
What is the difference between single and double strength window glass?
Single Strength Glass is 3/32" thickness and Double Strength Glass is 1/8" thickness.
Is double strength glass tempered?
No, double strength glass is just 1/8" thisck vs. 1/16" of single strength
Science fair do heating and cooling effect the strength of glass?
No, heating and cooling does not effect the strength of a glass
What does DSB Glass Stand for?
Double Strength Billet (DSB) glass
Do dislocations control the strength of silicate glass?
No,it is flaw size that control the strength.
Can we put something over glass wall?
It depends upon the strength of the glass.
What is the purpose of toughening the glass?
1.To provide the strength of the glass, 2.To obtain mass production of glass.

Can glass be sprayed to get tempered glass?
Um NO you temper glass the same as you temper any thing else. You have to heat it up. it cant be cut after it has been temoerd either. Cross section of glass has two areas, compressive strength area and tensile strength area. When glass is heated above 600 degree and fast cooled, the compressive strength area expands. Since glass has more compressive strength than tensile strength, it becomes difficult to break it. Tempered glass, especially toughened glasses are 4 to 5 times stronger than normal glass. These glasses break into small circular fragments. Normal glass breaks into sharp pieces and is a safety hazard.
