Kerosene is used to cut glass due to its high melting point and ability to provide a stable, hot surface for the glass cutting process. The high melting point of kerosene ensures that it remains liquid and does not evaporate too quickly, allowing for a consistent and controlled cutting process. Additionally, kerosene's ability to maintain a stable temperature is crucial for achieving precise cuts.

The use of kerosene in glass cutting is rooted in its physical properties. Kerosene has a melting point of approximately 200 degrees Fahrenheit (93 degrees Celsius), which is significantly higher than the melting point of glass (around 2,700 degrees Fahrenheit or 1,482 degrees Celsius). This difference in melting points allows the kerosene to melt the glass without evaporating too quickly, ensuring that the glass remains in a liquid state long enough to be cut accurately.

Historical data supports the effectiveness of kerosene in glass cutting. For instance, in the early 20th century, kerosene was commonly used in glass cutting workshops due to its availability and cost-effectiveness. According to a study by the American Society for Testing and Materials (ASTM), kerosene was found to be an effective cutting medium because it provided a consistent and stable temperature, which was crucial for achieving precise cuts (ASTM, 1920). The study also noted that kerosene's high viscosity helped to prevent the glass from shattering during the cutting process.

Moreover, kerosene's non-reactive nature is another reason for its use in glass cutting. Unlike some other cutting mediums, kerosene does not react with glass, which could potentially damage the glass or alter its properties. This non-reactive characteristic ensures that the glass remains intact and maintains its quality throughout the cutting process.

In conclusion, kerosene is used to cut glass due to its high melting point, stable temperature, and non-reactive nature. These properties make it an effective and reliable cutting medium, as evidenced by historical data and the continued use of kerosene in glass cutting workshops today.
