The Metallurgy Behind the Ritual
Long before the age of glass, plastic, or stainless steel - long before the concept of a 'drinkware industry' existed - India had already solved the question of what to drink from. The answer, refined across thousands of years of ritual, medicine, and daily life, was brass.
Not by accident. Not by scarcity. But by deep, deliberate knowledge of how metal interacts with the human body, the natural world, and the sacred cosmos.
This is the first entry in The Dhatu Diaries - The Kailasam's ongoing series on India's sacred metals. We begin where the story truly starts: with brass, its ancient chemistry, and why the rituals surrounding it were never mere superstition.
THE WORLD BEFORE MODERN VESSELS
A Material Chosen, Not Inherited
India's metallurgical tradition is among the oldest on Earth. Archaeological evidence from the Indus Valley Civilisation (circa 2600–1900 BCE) shows sophisticated copper smelting and alloying. By the Vedic period, the properties of various metals were not just understood — they were systematically codified in texts that have survived to this day.
Brass — an alloy of copper and zinc — was known in ancient India as Pittala or Arakuta. It occupied a singular place in the material hierarchy: strong yet workable, beautiful yet functional, spiritually resonant yet deeply practical. Priests used it in puja. Physicians prescribed it for healing. Households built their kitchens around it.
Brass was not what people drank from because they had nothing better. It was what they chose because nothing was better.
THE AYURVEDIC SCIENCE
What the Ancient Physicians Knew
The Ashtanga Hridayam, one of Ayurveda's foundational texts (circa 7th century CE), and the earlier Charaka Samhita both contain detailed references to the therapeutic use of metals in food and drink vessels. This wasn't alternative medicine — it was the mainstream medicine of an entire civilisation.
The Three Core Properties of Brass in Ayurveda
1. Pitta-Kapha Balance: Brass was considered tridosha-beneficial when used appropriately. Water stored in brass vessels overnight was observed to have a balancing effect on the Pitta (fire/heat) and Kapha (water/earth) doshas — two of the three fundamental energies in Ayurvedic physiology. For a tropical country like India, this was not a trivial claim.
2. Digestive Enhancement: Ancient physicians noted that water and liquids held in brass vessels aided digestion. Modern science has since confirmed this observation: brass ions - particularly copper and zinc - can stimulate digestive enzymes and support gut microbiome health.
3. Antimicrobial Activity: The Sushruta Samhita explicitly warns against drinking contaminated or stagnant water and prescribes metal vessels as a purification measure. Today we know why: brass exhibits what scientists call the oligodynamic effect - a well-documented antimicrobial property in which trace metal ions kill or suppress the growth of bacteria, fungi, and viruses.
MODERN SCIENCE CONFIRMS ANCIENT WISDOM
The Chemistry of the Sacred Cup
It would be easy to dismiss the ancient reverence for brass as ritual symbolism. Science, however, has largely validated the material logic behind it.
The Oligodynamic Effect: First described in modern terms by Swiss botanist Wilhelm von Nägeli in 1893, the oligodynamic effect refers to the toxic (to microorganisms) action of small concentrations of heavy metal ions. Copper — a primary constituent of brass — is particularly potent in this regard. Studies have shown that E. coli, MRSA, Salmonella, and even influenza viruses are destroyed within hours on copper surfaces.
Zinc and Immune Function: Brass's second major component, zinc, is today recognised as essential to immune function, wound healing, and cellular metabolism. Trace dietary zinc is now a cornerstone of modern nutritional science — something Ayurvedic practitioners intuited millennia before zinc was isolated as an element in 1746.
pH Modulation: Research published in peer-reviewed journals has confirmed that water stored in copper alloy vessels undergoes measurable pH changes, becoming slightly more alkaline. Alkaline water has been associated with antioxidant properties and improved hydration at the cellular level — again, consistent with Ayurvedic claims about tamrjal and its derivatives.
When a 3,000-year-old text and a 21st-century laboratory reach the same conclusion, it is worth pausing to ask: what else did they get right?
RITUAL, ROYALTY & THE TEMPLE
Why Brass Became Sacred
The journey of brass from the physician's dispensary to the temple altar was not accidental. In Hindu cosmology, the five classical elements — Pancha Bhuta — underpin all material reality. Metals, as condensed forms of earth energy, carry their own elemental signature. Brass, born from the union of copper (associated with Surya, the Sun) and zinc (associated with purification and preservation), was considered to carry complementary divine energies.
In the domestic sphere, brass vessels were among the most carefully maintained objects in a traditional Indian household. They were cleaned with tamarind or ash — both mildly acidic agents that prevent excessive oxidation while preserving the metal's active surface. They were never left empty for long periods. They were passed down through generations, each year of use considered to deepen the vessel's virtue rather than diminish it.
Temple vessels — the kalashas, the puja thalis, the ritual cups — were almost universally made of brass or its close relative, bell metal (an alloy of copper and tin). The choice was not simply aesthetic. A metal that purifies water, balances the body, and conducts spiritual energy was the natural vessel for offerings to the divine.
The Peacock and the Patron
Royal courts of medieval India elevated brass to an art form. The intricate Bidriware tradition of the Deccan, the Dhokra casting of Central India, and the engraved brassware of Moradabad — just an hour's drive from our atelier in Agra — represent centuries of accumulated mastery. Artisans did not merely make vessels; they encoded cosmology into them.
The peacock motif — still central to The Kailasam's design language — is among the oldest recurring symbols in Indian metalwork. As the vehicle of Saraswati (goddess of wisdom and arts) and the embodiment of beauty emerging from the mundane, the peacock on a brass vessel was a statement of values: that beauty and function are not in opposition, that the sacred and the everyday are not separate.
LIVING WITH BRASS TODAY
The Case for Bringing Brass Back
We live in an era of material anxiety. Single-use plastics are rightly condemned. Stainless steel is functional but cold. Glass is beautiful but fragile. Ceramic is ancient but passive.
Brass offers something none of these can: a material relationship. It ages with you. It responds to how you care for it. Its patina tells a story. And its fundamental properties — antimicrobial, pH-active, durable across generations — are not marketing claims. They are chemistry.
The Kailasam's brass wine glasses and drinkware are not replicas of historical objects, nor are they attempts to make brass seem modern by disguising what it is. They are an acknowledgment that certain design problems were solved long ago, and the wisdom embedded in those solutions deserves not nostalgia, but revival.
To drink from brass is not to reach backward. It is to recognise that some knowledge transcends the century in which it was written.
CARE & RITUAL
How to Care for Your Brass
Brass, like all living materials, asks for a small ritual of its own.
Daily: Rinse with clean water after use. Avoid leaving acidic beverages (citrus juices, vinegar-based drinks) to sit for extended periods.
Weekly: A gentle clean with a soft cloth and mild soap is sufficient. Do not use abrasive pads, which scratch the surface and disrupt the patina.
Monthly: For a deeper clean and polish, a paste of tamarind, lemon juice, or a small amount of baking soda with water will restore the warm gold tone. Rinse thoroughly.
The Patina Question: Brass naturally develops a patina over time — a darker, warmer tone that many consider more beautiful than the original bright gold. This is not damage. It is the metal reaching its character. If you prefer the brighter finish, the monthly polish described above will maintain it. If you let the patina develop, you are holding an object that reflects your life.
IN CLOSING
The Dhatu Diaries Continues
This series exists because we believe that the objects we use daily are not neutral. They carry material histories, cultural memories, and scientific properties that matter - even when we are not conscious of them.
Brass was not chosen by accident. It was chosen by civilisations that paid close attention to how materials interact with life. We think that knowledge is worth recovering, worth celebrating, and worth building beautiful objects around.
In the next entry of The Dhatu Diaries, we go deeper into copper - specifically into the ancient practice of Tamra Jal, the science of copper-stored water, and why Ayurvedic texts prescribed it as a morning ritual for over two thousand years.
Until then - drink well, drink beautifully.
