§1What this business is
Plain sheet glass bought from large glass makers is loaded, ground and cut to the customer's sizes, washed, edge-polished and notched or drilled, then heated in a toughening furnace and quickly cooled by air blowers. The glass becomes much stronger and breaks into small blunt pieces. It goes into doors, partitions, railings, shopfronts, furniture tops, vehicles and greenhouses.
Capacity: 48,000 sq m of toughened glass a year; sold at ₹850 a sq m.
§2Is it right for you?
Who it is for
Someone with glass-processing or building-material sales experience and contacts with builders, as the report advises.
Who it is not for
Someone in a small town with little construction activity.
Advantages
- Modern buildings use toughened glass for doors, partitions and facades
- Raw sheet glass is easy to buy from large makers
- Healthy margin in the report (about 13% before tax)
- Every order is cut to size, so local service wins
Drawbacks
- ₹1.32 crore of furnace and processing machines
- Market is mostly local — location decides success
- Glass cannot be cut after toughening, so measuring errors are costly
- Breakage in handling and transport
Skills you need
- Furnace operation and toughening

Why difficulty 4/5: Costly furnace, skilled processing and a market that must be near you.
