Common glass (called soda lime glass) is made from sand, SiO2, Na2O and CaO. Lead may be added to make the glass more flexible, or to improve its refractive index and make it sparkle, such as in crystal glasses.
[We add the Na2O) to lower the melting point and thus lower cost, but this makes the glass more soluble (!) and we add the CaO to counter this.]
You must have seen glass bottles with a bluish bloom on them - this is solution attack - often from alkali.
Pure SiO2 glass is used where high melting point is needed, and where the contamination from the Ca or Na could not be tolerates in a scientific process.
Borosilicate glasses have great use, for their composition can be tailored to have an essentially zero temperature expansion. Of great use in lab glassware, oven doors, and stove tops.
Ammonia is a compound of the elements hydrogen and nitrogen.
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.
Glass is primarily made of silica sand, soda ash, and limestone, combined and heated to form a liquid which is then cooled to create the solid glass material. Concrete is typically a mixture of cement, water, sand, and aggregate such as gravel or crushed stone. The combination of these materials in specific proportions results in the final properties of glass and concrete.
False. Hydrogen and oxygen - both gases - combine to form water - a liquid.
Yes, elements combine in specific ratios to form compounds. A compound is a substance made up of two or more different elements chemically bonded together. The chemical bonds between elements in compounds are formed through interactions at the atomic level.
To make a satellite in Little Alchemy, you need to combine the elements "glass" and "sky." First, create glass by combining "sand" and "air." Then, combine the glass with the sky to produce a satellite.
To make an hourglass in Alxemy, combine the elements of "sand" and "time." First, create "sand" by mixing "earth" and "fire" to produce "glass." Then, combine the "glass" with "time" to form the hourglass. This process reflects the game's mechanics of combining different elements to achieve new items.
Common glass is made from sand, SiO2, Na2O and CaO. Concrete is a mixture of rocks (aggregate), sand, and water.

To make a desert in Doodle God, combine the elements of sand and life. First, create sand by mixing earth and fire to form glass, then combine glass with earth. Once you have sand, mix it with life to produce a desert. Enjoy experimenting with other combinations to expand your world!
Elements chemically combine to make molecules.
In Little Alchemy, you can create sunglasses by combining "glass" and "fashion." First, create glass by combining "sand" and "fire." Then, combine the resulting glass with "fashion" to produce sunglasses. Enjoy mixing elements to discover more items!

To create an hourglass in Doodle God 2, combine sand with glass. First, ensure you have both elements available in your inventory. Once you have them, simply drag sand onto glass to craft the hourglass. This combination highlights the game's mechanics of mixing basic elements to create more complex items.
