§1What this business is
Clays, feldspar and quartz are ground in a ball mill, mixed into slip in a blunger, filter-pressed into cakes, extruded in a de-airing pug mill, shaped, dried, glazed and fired in a kiln. Metal fittings are cemented on, and each piece is tested for dimensions and defects before packing in wooden blocks.
§2Is it right for you?
Who it is for
Someone with ceramics or electrical-goods experience and contacts with utilities or contractors.
Who it is not for
A first-time founder with no technical help — quality testing is strict.
Advantages
- Steady demand from power distribution and wiring
- Raw clays and minerals are available in India
- Margin improves as capacity rises
- Machinery under ₹14 lakh
Drawbacks
- Firing in a kiln takes skill; rejects are costly
- Needs a large shed area
- Utilities buy through tenders with strict tests
- Several approvals: BIS, factory, fire, pollution
Skills you need
- Body and glaze formulation
- Kiln firing control
- Mechanical and electrical testing
- Tender paperwork
Why difficulty 4/5: Ceramic firing, testing and approvals make this a technical business.
