Ancient Hindus used Nanotechnology

Ancient Hindus unknowingly employed nanotechnology in the manufacture of swords, other weapons and paintings. This was indicated by Nobel Laureate (chemistry) Robert Curl Jr at the 95th Indian Science Congress in Visakhapatnam, Andhra Pradesh, India.

‘Our ancestors have been unwittingly using the technology for over 2,000 years and carbon nano for about 500 years. Carbon nanotechnology is much older than carbon nanoscience,’ said Curl (the Hindu)

Nobel Laureate (chemistry) Robert Curl Jr told an enchanted audience at the 95th Indian Science Congress here about how Damascus steel was first made by experts in south and south-central India as long ago as around 300 BC. (the New Indian Express)

The swords produced by ancient Hindu blacksmiths were known to retain its sharp edge and toughness. Such high quality swords were the result of the composition of carbon in it.

Nanotechnology refers broadly to a field of applied science and technology whose unifying theme is the control of matter on the atomic and molecular scale, normally 1 to 100 nanometers, and the fabrication of devices within that size range. (Wikipedia)

The raw material used by ancient Indians was wootz steel – a high grade steel first made in ancient South India. After burning away the impurities in the iron ore, important ingredients including a high carbon content of nearly 1.5 per cent was added to produce wootz steel.

A similar method was employed in Ajanta paintings.


  1. So what does it all mean… the wonders I saw at Ajanta and Ellora caves, the serenity and beauty of the paintings, the elaborately sculptured treasures… all result of such high technology??

    Do you have any other material linking both?

  3. As soon as I get more materials, I will be updating the post.
    It must be remembered that the ancient Hindus used these methods to improve upon their existing methods…they were not bothered about technology and even did not bother to name it. They did not have any economic interest like modern day people. Their primary aim was to attain perfection in their work.

  4. This is perfectly demonstrated in ancient Indian culture as we see dedicated artists in India.The science is called artist views in those days.

  5. There are several events that portray that ancient Hindus had a lot of knowledge and information about some of the most modern technologies we have today. And we also know that since this knowledge was not easy to understand by the common people, only some cults were provided with the knowledge - first by mouth, and later in the form of text. I also understand and agree that not all of the knowledge was documented as text.

    Although, my question here is that, if these technologies were passed from the gurus to their disciples - by whatever means possible, was the chain broken so badly present generations are spending their lives 'reinventing the wheel'..
