Hint :Glass is made up of natural and abundant raw materials like sand, soda ash and limestone that are melted at high temperature to form glass. Naturally occurring raw materials like silca, sand, quartz, flint, silicates and aluminosilicates are used in the manufacturing of ceramics.
Complete Step By Step Answer:
The sand used in the preparation of glass has small grains of quartz crystals which are made up of silicon dioxide also called silica. Ceramics are prepared by taking mixtures of clay, powders, earthen elements and water. These are shaped into desired forms. After shaping, it is fired in a high temperature oven called kiln. Feldspar is a very important raw material in the manufacture of glass because it acts as a fluxing agent, reducing the melting temperature of quartz. It also helps in controlling the viscosity of glass. In the manufacturing of ceramics, it is the second most important ingredient.
Therefore, option B is the correct answer.
Note :
Ceramics are inorganic, non-metallic solids made up of either metal or nonmetal compounds that are shaped and hardened by heating to high temperatures. They are generally hard, brittle and resistant to corrosion. Glass is not considered a ceramic due to its amorphous nature. But several steps of the ceramic process are involved in glass making and its mechanical properties are the same as those of ceramic materials.
