Copper Wisdom

The ritual of tamra jal

Living with copper, brass and kansa — how to use them, and how to keep them beautiful for generations.

Hammered copper Ganga wati
The morning ritual

Fill at night. Drink at dawn.

In Ayurvedic tradition, water stored in a copper vessel for six to eight hours — tamra jal — is sipped first thing in the morning.

  1. Fill your copper bottle, jar or Ganga wati with room-temperature drinking water at night.
  2. Leave it covered, away from direct sunlight.
  3. Drink a glass or two in the morning, then rinse and refill.

Copper vessels are for plain water only — avoid storing lemon water, juices, milk or other acidic drinks in unlined copper. This is traditional practice, not medical advice; please consult a doctor for health concerns.

Know your metal

Pure, steel-lined or kalai-lined?

Pure Copper

Solid copper inside and out. Ideal for storing and drinking water — bottles, jugs, glasses, jars and matka tanki. Not for cooking or acidic foods.

Steel–Copper

Stainless steel and copper in one piece. Each product page says which metal is on the inside: where it is steel, use it for hot food and any drink; where it is copper, use it for plain drinking water only.

Kalai (Tin) Lined

Copper or brass cookware lined with a thin layer of pure tin — the traditional way to cook safely in these metals. Kalai can be re-applied by a local kalaiwala when it wears.

FAQs

Questions, answered

Is it good to drink water from a copper bottle?
Drinking water stored in a copper vessel, called tamra jal, is a centuries-old Ayurvedic practice. Traditionally, water is kept in a pure copper bottle or jar for 6–8 hours (usually overnight) and drunk in the morning. Use plain drinking water only, and consult a doctor for any health concerns; this is traditional practice, not medical advice.
How long should water be kept in a copper bottle?
Traditionally 6–8 hours, typically overnight. Refill the bottle with fresh water every day rather than storing the same water for several days.
Can I put lemon water, juice or milk in a copper bottle?
No. Do not store lemon water, juices, buttermilk, milk or other acidic drinks in unlined pure copper. Use pure copper bottles, jugs and jars for plain drinking water only.
How do I clean a copper bottle?
Rinse with water and dry after use. Once a week, scrub with half a lemon dipped in salt (or a paste of vinegar, salt and flour), rinse well and dry with a soft cloth. Avoid dishwashers and steel scrubbers. Antique and meena-painted finishes only need a soft dry cloth.
What is the difference between pure copper and steel-copper?
Pure copper pieces are copper inside and out, and are meant for storing plain drinking water. Steel-copper pieces combine stainless steel and copper: where the inside is stainless steel (stated on each product), they can hold any drink or hot food; where the inside is copper, use them for plain drinking water only.
What is kalai (tin) coating?
Kalai is a thin layer of pure tin applied to the inside of copper and brass cookware. It is the traditional way to make these metals safe for cooking. When the kalai wears off after years of use, a local kalaiwala can re-coat it.
Is kansa (bronze) good for eating?
Kansa, or bell metal, is a traditional Indian alloy long valued in Ayurveda for thalis, bowls and glasses. Wash it with mild soap, dry it immediately, and polish occasionally with tamarind to keep its golden shine.
What are good copper gifts for weddings, Diwali or housewarming?
Popular choices are copper bottles and lemon sets (wellness gifts), matka tanki water dispensers (housewarming), brass urulis and puja lotas (Diwali), and thali or dinner sets (weddings and shagun). For 25 or more pieces, see our Bulk & Corporate Orders page.

How do I know if copper is real?
Pure copper is not magnetic, turns bright pink when rubbed with lemon and salt, is copper-coloured inside and feels heavy for its size. See our pure copper test guide and the Rivaj Purity Promise.
Why has my copper turned dark?
Copper naturally oxidises when it meets air and water — it's a sign of genuine copper. A quick polish with lemon and salt restores the shine.
Can I cook in copper?
Only in copper that is lined, with kalai (tin) or stainless steel. Each product page states whether a piece is kalai- or steel-lined. Unlined pure copper is for water only, and unlined brass is best for dry use such as storage.
Do you do corporate and bulk orders?

Each piece is handmade, so hammer marks, embossing depth and tone vary slightly. This is the mark of handcraft.
