Question

The melting point of glass is not fixed, why?​

Answer 1

Glass does not have a fixed melting point as water has. Rather, as glass is heated, it softens more and more and melts gradually over a wide temperature range. The hotter it gets, the more easily the glass flows. The resistance of a liquid to flow is called its VISCOSITY.

☆Because Glasses have various components in it , it is IMPOSSIBLE to determine its SPECIFIC MELTING POINT ~

• ☆Glass can only be molded at very high temperatures. It completely melts/liquifies at approximately 1400 °C to 1600 °C depending on the composition of glass. Glass is made from a variety of substances, depending on the intent of use. Mostly sand, lime and soda are what most glasses are made of. There are many types of glasses ex, bulletproof, tempered, tinted, stained, etc.

• ☆Melting is the process where a solid becomes a liquid (ex. ice melts to water) which is more or less abrupt.You see glass doesn't actually melt persay. Rather it goes through a glass phase transition. Meaning that when it comes to glass "melting"it's a more gradual process. It doesn't melt but it keeps on softening until it can sort of flow wherefore we can be able to mold it into whatever shape we desire.
