40) Arrange the following steps in a sequence for the manufacture of glass
The correct option is A 2134
Explanation for the correct option -
(A) The manufacturing of glass is done in the following sequence:
(2) Mixing of raw materials in proper proportion - Silica, limestone, and feldspar are used as major raw materials.
(1) Addition of cullet - Cullet is the crushed glass pieces that are ready to be melted at low temperatures. Cullet is added to raw materials.
(3) Addition of coloring pigments - Some coloring pigments like red lead etc. are added to give specific characteristics to the glass.
(4) Annealing - The product formed till step (3) is heated strongly so as to change the physical properties of glass and convert them to the desired shape so that it becomes more workable.
Hence option ‘A’ is the correct choice for the sequence of steps for the manufacture of glass.
