Correct option is C
The correct answer is option (C) sand and silicates.
Glass is primarily made from a mixture of silicon dioxide (SiO2), commonly found in sand, and various silicates (compounds containing silicon and oxygen, often with metals like sodium, calcium, or potassium). These materials are melted at high temperatures to form glass. The most common type of glass is soda-lime glass, which consists mainly of silica (from sand), soda (sodium carbonate), and lime (calcium oxide).
Information Booster:-
- Quartz and mica: Quartz is a form of silicon dioxide and is a component of glass, but mica is not a major component of glass. Mica is more often used in electrical insulation or as a filler material.
- Sand and salt: While sand is an important ingredient in glassmaking (due to its high silica content), salt is not used in the production of glass. Salt is used in some industrial processes but not in glass manufacturing.
- Silicates and quartz: While quartz is a type of silicate, the phrase “silicates and quartz” is too vague to represent the typical components of glass accurately. The term silicates covers a broad range of materials, but glass is primarily made from sand (silica) and other silicates, like sodium silicate or calcium silicate, depending on the type of glass
