Introduction: The Living Metal Heritage of Assam | How Bell Metal Products of Assam Are Made
Among Assam’s many traditional crafts, bell metal products hold a special place for their durability, cultural value, and artistic excellence. From ritual utensils to everyday kitchenware, bell metal items have been an inseparable part of Assamese life for centuries.
The craft is most famously practiced in Sarthebari, a small town in Bajali district, often called the “Bell Metal Hub of Assam.” What makes this craft extraordinary is that even today, most bell metal products are made using age-old manual techniques, passed down through generations.
So, how are bell metal products of Assam made?
Let us take a detailed journey through the traditional process, tools, and cultural importance of this timeless craft.
1. What Is Bell Metal?
Bell metal is a traditional alloy made primarily of:
- Copper (around 78–80%)
- Tin (around 20–22%)
This specific combination gives bell metal:
- High strength and durability
- A distinctive golden-bronze shine
- Clear ringing sound when struck
Because of these qualities, bell metal is ideal for utensils, religious items, and ceremonial objects.
2. Historical Roots of Bell Metal Craft in Assam
The bell metal craft of Assam dates back over 700 years, flourishing during the Ahom dynasty. Kings and nobles patronized artisans to produce:
- Royal utensils
- Temple offerings
- Ritual objects
Over time, the craft became deeply embedded in Assamese households, especially during festivals, weddings, and religious ceremonies.
3. Sarthebari: The Heart of Bell Metal Craft
Sarthebari artisans are known locally as Kanhars, skilled metal craftsmen who:
- Inherit the craft within families
- Learn techniques from childhood
- Preserve traditional knowledge without written manuals
Today, Sarthebari produces over 90% of Assam’s bell metal items.
4. Raw Material Preparation
The process begins with sourcing:
- High-quality copper
- Pure tin
These metals are carefully measured to maintain the correct alloy ratio. Even a small imbalance can affect:
- Strength
- Color
- Sound quality
The metals are cleaned thoroughly before melting.
5. Melting the Alloy
Traditional Furnace (Bhati)
- Made from clay and bricks
- Fueled by charcoal or firewood
The copper is melted first due to its higher melting point. Once molten, tin is added carefully and mixed using iron rods.
This molten alloy becomes bell metal, glowing bright orange at extremely high temperatures.
6. Casting the Metal Blocks
The molten bell metal is poured into:
- Stone molds
- Clay molds
These molds create solid metal blocks or discs, known locally as pitha.
After cooling, the blocks are removed and cleaned for the next stage.
7. Heating and Hammering: The Soul of the Craft
This is the most crucial and labor-intensive stage.
Repeated Heating
- Metal blocks are reheated multiple times
- Heated until red-hot
Manual Hammering
- Artisans hammer the metal on stone anvils
- Shape is formed gradually through repeated blows
- Requires perfect coordination and experience
This process can take several days for a single product.
8. Shaping Different Bell Metal Products
Depending on the item, artisans shape the metal into:
- Kahi – traditional Assamese plates
- Bati – bowls
- Lota – water vessels
- Ban Bati – ritual containers
- Doba – large cooking vessels
Each product has specific thickness, curvature, and weight standards.
9. Trimming and Finishing
Once the desired shape is achieved:
- Edges are trimmed using chisels
- Surface is smoothed manually
- Minor imperfections are corrected
No machines are used in traditional finishing, ensuring handcrafted uniqueness.
10. Polishing the Bell Metal
Polishing gives bell metal its signature shine.
Traditional Polishing Methods
- Sand, ash, and tamarind
- Natural oils
- Manual rubbing
This enhances:
- Appearance
- Longevity
- Resistance to corrosion
11. Quality Testing
Experienced artisans check:
- Sound clarity (by tapping the item)
- Thickness consistency
- Structural strength
Only pieces that meet traditional standards are sold.
12. Cultural Importance of Bell Metal in Assam
Bell metal products are essential in:
- Weddings and festivals
- Naamghar and temple rituals
- Daily meals in traditional households
In Assamese culture, serving food in bell metal utensils is considered pure and auspicious.
13. Health Benefits of Bell Metal Utensils
Traditional belief and modern research suggest that bell metal:
- Helps retain food warmth
- Has antimicrobial properties
- Enhances taste of food
- Supports better digestion
This is why bell metal utensils are still preferred in many Assamese homes.
14. Challenges Faced by Bell Metal Artisans
Despite its cultural importance, the craft faces challenges:
- Rising raw material costs
- Competition from machine-made utensils
- Declining number of young artisans
Supporting authentic bell metal products helps preserve this heritage.
