Explanation

To describe the major techniques applied on the molten glass obtained during the manufacture of glass to achieve the desired variety of glass, we can outline the following steps:

### Step-by-Step Solution:

1. **Blowing of Glass**:
- This technique involves inflating molten glass into various shapes using a blowpipe.
- It is primarily used for creating laboratory glassware, bottles, and other hollow glass items.
- The glassblower gathers molten glass on the end of a blowpipe and blows air into it, forming the desired shape.
