[3] A two-year training programme for student craftsmen is organised by the Tamil Nadu Handicrafts Development Corporation Ltd, known as Poompuhar, in Nachiarkoil.

As the Pathers were not aware of using sheets to manufacture handicrafts, they adopted it to their own craftsmanship in which they were proficient, of using a moulding brass and bell-metal technique using a particular type of sand.

They settled at Nachiarkoil, as they found the light brown sand available in the nearby Cauvery river bed was exclusive and most suitable to mould their products.

The lamp has four components which are: parts—base "Keezhbagam (base plate), "kandam" meaning pivotal post, "Thanguli" a bowl with five groves to hold wicks and oil for lighting, and the "Prabhai" which is the crown.
