Silicon and oxygen
Common glass is made from sand, SiO2, Na2O and CaO. Concrete is a mixture of rocks (aggregate), sand, and water.
Silicon and oxygen are the two elements that you combine to make sand. =]
No, no I cannot answer this question. Obviously, I don't know.
Silicon and Oxygen make up sand.

In the game Little Alchemy, to create silicon, you need to combine two elements: sand and electricity. Sand is represented by the basic element Earth, and electricity is represented by the basic element Energy. By combining Earth and Energy in the game, you will create silicon.
Without modifiers, the word "sand" refers to a substance that is almost entirely silicon dioxide.
Common glass is made from sand, SiO2, Na2O and CaO. Concrete is a mixture of rocks (aggregate), sand, and water.
Glass is made from sand, soda ash, and limestone, which are melted together to create a transparent material. Concrete is made from cement (a mixture of limestone, clay, and other minerals), water, and aggregates such as sand and gravel, which form a solid, durable material when mixed together.

Glass is made by combining sand, soda ash, and limestone, which are heated together to form a molten mixture that solidifies into glass. Concrete is made by combining cement, water, sand, and gravel, which form a paste that hardens into a solid material.
