How the National Emblem on the new Parliament building was designed and why it is unique

New Delhi, July 11: Prime Minister Narendra Modi on Monday unveiled the national emblem cast on the roof of the new Parliament building here.

The inauguration of the emblem, which is made up of bronze with a total weight of 9,500 kg and is 6.5 metre in height, marks the first major milestone ahead of the new building's scheduled opening for later this year.

The 6.5-meter State emblem of India, weighing 16,000 kg is fully hand crafted by Indian artisans, is made of high purity bronze.

There is no other similar depictions of the emblem, from the perspective of material and craftsmanship, anywhere else in India.

Over 100 artisans from various parts of the country tirelessly worked on the design, crafting and casting of the emblem for over six months to bring out the quality that could be seen in the final installation.

The installation itself was a challenge as it was 32 meter above upper ground level.

Giving wings to the ambition of creating such an expression of the State emblem needed dedication, meticulous supervision, and skilful installation - all depicting various elements of Atma Nirbhar Bharat. When it is seated at the top of the temple of our democracy - the Parliament building, it truly represents the paradigm of 'for the people, by the people'.

Design:
The State Emblem of India is an adaptation from the Sarnath Lion Capital of Asoka which is preserved in the Sarnath Museum. The Lion Capital has four lions mounted back-to-back on a circular abacus. The frieze of the abacus is adorned with sculptures in high relief of an elephant, a galloping horse, a bull, and a lion separated by intervening Dharma Chakras.

The profile of the Lion Capital has been adopted as the State Emblem of India. This finds pride of place and the design is adopted for the emblem above the parliament building.

Process of casting the National Emblem:

A computer graphic sketch was made and based on that a clay model was created once approved by competent authorities the FPR Model was made. Then with the lost wax process the wax mould and bronze cast was done.

The process of lost wax casting:

To cast the clay into a bronze a mould is made from the model, and the inside of this negative mould is brushed with melted wax to the desired thickness of the final bronze. After removal of the mould, the resultant wax shell is filled with a heat-resistant mixture. Wax tubes, which provide ducts for pouring bronze during casting and vents for the gases produced in the process, are fitted to the outside of the wax shell. Metal pins are hammered through the shell into the core to secure it. Next, the prepared wax shell is completely covered in layers of heat-resistant fibre reinforced plastic, and the whole is inverted and placed in an oven. During heating, the plaster dries and the wax runs out through the ducts created by the wax tubes.

The plaster mould is then packed in sand, and molten bronze is poured through the ducts, filling the space left by the wax. When cool, the outer plaster and core are removed, and the bronze may receive finishing touches.

Finally the statue is polished and breezed and ready with clear coat of protective polish and no paint to showcase the rich metal.
