Heating the cut edges
Glass is a delicate material which is used in manufacturing various things. There are two types of glass like Soda-lime glass and Borosilicate glass. Soda-lime glass can be melted easily at 300-400°C and Borosilicate glass cannot be easily melted and it requires 700-800°C to soften it. Hence Borosilicate glass is used in manufacturing glass apparatus used for laboratory purpose.
To know the basic techniques of cutting glass tube and glass rod using a simple process.
Glass is an amorphous solid crystalline structure having tightly packed molecules. Hence Glass does not possess a sharp melting point.
The jagged edges might cause injury while handling, hence for the safety and to give good look with a smooth finish, edges of glass tube or rod is rounded off.
To ensure the uniform heating glass tube is rotated while heating.
