What is the melting point of glass?

The melting point of glass can vary depending on its composition, but it typically ranges from approximately 1200 degrees Fahrenheit to 1400 degrees Fahrenheit. Option B, stating 1200 degrees, represents a common temperature reference for certain types of glass, particularly common soda-lime glass.

This temperature is significant in fire investigations because glass can provide crucial evidence regarding the intensity and duration of a fire. If glassware found at a scene is melted, it suggests that temperatures reached were sufficient to exceed this melting point, indicating a severe fire incident.

Other options represent higher temperatures, which may be applicable to specific glass types or formulations that have higher melting thresholds, but the choice of 1200 degrees is a realistic approximation for many standard glass materials relevant to fire investigations. Understanding this melting point helps investigators assess fire dynamics and determine potential fire behavior in different environments.
