Bronze Utensils – Health Benefits and Properties

Bronze, an alloy of copper and tin mixed, is known as ‘kansa’ in Hindi speaking belt of India and ‘kanh’ in Assam and other parts of north-eastern India. Though Copper was in use for much longer, it was bronze that changed the way sculptures, tools, ornaments and kitchen utensils were made, around 3000 years, thus the name Bronze Age.

A number of bronze artefacts that have been unearthed in archaeological findings are, in fact, kitchen items such as cooking pots, bowls and plates. 

The metal finds mention in our ancient scriptures, particularly in Ayurveda texts, wherein elaborate accounts of use of bronze kitchenware are given. There is a clear mention of the health benefits of Bronze utensils in these scriptures. One such text to quote is the ‘Rasaratna Samucchaya’.

Traditional kitchens in India still make use of traditional metal or metal alloy utensils, including those made in bronze. While in north India, there is use of bronze ‘kadaais’ for cooking. In Tamil Nadu, these pots are called by name of Vengala Paanai and in Kerala by name of ‘Bronze Uruli’. 

Last few decades have seen modern homes move towards the Teflon coated non-stick cooking ware, which is now believed to be harmful for the body.

However, as there is growing awareness in present generation, the bronze-based and other traditional utensils are increasingly being used more and more in kitchens.


Where to find Bronze Utensils in India…

Bronze utensils are made in certain areas which are specially noted for metallurgical works. These centers manufacture different types of commerical use and decorative items from bronze metal.
Jagadhari is a well known town in North India famous for making metal utensils, including those of bronze. Another famous center is Jandiala Guru, close to Amritsar, where Thathera community is known for their age-old tradition of making metal utensils. Moradabad in Uttar Pradesh is another major center of brass works but bronze works and other copper alloy metal works are also performed here.

Bronze works and utensil making are also common in Thanjavur district, Swamimalai and Chennai in Tamil Nadu. Khagra in Mushidabad district and Nadia area of Bengal in East India also make bronze artefacts. Parev in Bihar is another major center for brass and bronze utensil making.

Munnar in Kerala is another important town known for its metal works and making of utensils. It is next only to Moradabad in North India.

Traditionally, Moosaries and Acharies communities within the larger Vishwakarma community have been doing this work.


How are Bronze utensils made?

Bronze is made by mixing copper (78%) and tin (22%) and heating at about 400-700 degree Centigrade. Bronze is malleable and can be drawn into sheets. This property allows for working on it to give desired shape. The molten metal is then moulded to form different utensils and the polishing is done by sand and tamarind juice. 


Why Bronze for the earlier age Utensils?

Bronze is a durable alloy. Most of the artefacts that have been unearthed are still intact after thousands of years. It is because the alloy is resistant to wear and tear and can also remain scratch and wrinkle resistant for decades.

Bronze is tough to destroy. When exposed to moisture, bronze develops a coating which performs protective function.

Kansa ‘Bronze’ is also a good conductor of heat and is also capable of retaining heat. This helps in keeping food warmer and keeps its contents richer for a long period of time.

Kansa utensils also have germicidal properties. Depending upon the variation in type, concentration and medium of pathogens bronze metal kills these micro-organisms.
