I need to know which substance and which substance combine together to form the glass as my teacher taught me sodium oxide and calcium oxide,so i need to know is it correct or not.

it is made by fusing soda ash(anhydrous sodium carbonae),sand,limestone.its molecular formulae is na2o.cao.6sio2 and it is the cheapest glass and is easily attacked by chemicals

Soda-Lime Glass
- composed of lime, silica and soda melted at a relatively low temperature, is easy to form, has good chemical durability and is inexpensive.
that is : sodium carbonate , calcium oxide and siO2

sodium oxide is nasty. It is the safe carbonate that is used. The calcium oxide is used and is better known as lime. Not quite so nasty.

In terms of reactivity, normal glass is pretty much the same as borosilicate glass, so you can use it for storage. However, due to the different compositions, there may be some more leaching of cations (mainly sodium and potassium), but that happens in borosilicate glasses, too, and should not be very important except for trace analytics.

it is made by a mixture of lime stone and sodium carbonate.
it is used as a window glass. it is also known as a soft glass
