Answer

To determine which type of glass is used in making the windscreen of automobiles, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Options**: First, we need to know the different types of glass that are typically used in various applications. The common types include:
- Soda-lime glass
- Borosilicate glass (Pyrex)
- Safety glass (tempered or laminated)

2. **Understand the Requirements for Windscreens**: The windscreen of an automobile must meet specific criteria:
- It should be strong and durable to withstand impacts.
- It should be less likely to shatter upon impact to prevent injury to passengers.
- It should provide clear visibility.

3. **Evaluate Each Type of Glass**:
- **Soda-lime glass**: This is the most common type of glass but is not suitable for windscreens as it can shatter easily.
- **Borosilicate glass (Pyrex)**: While this glass is heat-resistant and used in laboratory glassware, it is not typically used for windscreens due to its brittleness.
- **Safety glass**: This type includes tempered glass and laminated glass, which are designed to be more durable and shatter-resistant. If broken, they break into small pieces or remain intact, reducing the risk of injury.

4. **Conclusion**: Based on the evaluation, the type of glass used for making windscreens in automobiles is **safety glass**. This glass meets the necessary safety standards and requirements for automotive use.

### Final Answer:
Safety glass is used in making the windscreen of automobiles.
