FAQs
Why doesn’t copper stay the same color?
Copper naturally develops a patina over time. This happens when copper reacts with oxygen in the air and forms a thin layer of copper oxide. This layer protects the metal from deeper corrosion and is a normal, healthy process.
The change is reversible. To restore shine:
Clean with lemon juice diluted in water
Rinse and dry thoroughly
Use copper cleansing powder such as Pitambri
We include a complimentary sample of copper cleansing powder with your purchase to help maintain the original finish.
Copper is also traditionally associated with wellness benefits and is valued for its antioxidant and antimicrobial properties.
Why do copper bottle caps sometimes tighten?
Copper is softer and less tensile than steel. Over time, slight expansion or friction can make caps feel tight.
To fix this:
Apply a small amount of edible oil around the cap seal and rim
Let it sit briefly
Gently twist open
This restores smooth functionality without damaging the threads.
Why are some products delivered with dents or scratches?
Copper is a soft, malleable metal. Because our products are handcrafted, minor surface variations can occur during production or transit.
Small dents can often be corrected by:
Gently pushing from inside with your hand
Tapping lightly with a rubber mallet
These characteristics are part of artisanal craftsmanship and do not affect durability.
How much copper water should you drink daily?
Store water in a copper vessel overnight and drink at least one glass in the morning. For best results:
Water should remain in the vessel for ~16 hours
Drink in moderation as part of a balanced routine
What does water stored in copper taste like?
Water stored in copper tastes clean and fresh. There may be a faint metallic note, but it is subtle and does not significantly alter flavor.
Should I clean my copper vessel before first use?
Yes. Rinse with water and clean using the provided copper cleansing powder before first use. This removes polishing residue and prepares the vessel for drinking.
Can copper bottles be refrigerated or used for hot water?
Do not freeze copper bottles
Short refrigeration is acceptable
Avoid boiling water
Lukewarm or room-temperature water is ideal
Extreme temperatures can stress the metal and seals.
