The Engraving

The same mark, at drinking height.

One lotus rosette, laser-cut into the side of the glass where a thumb sits. The same mark the dinner set carries — which is what makes the two read as one range rather than two purchases.

Kansa Glass

In detail.

Why you'll love it

Bronze does something to water that steel does not: it takes the chill slowly, sits heavy in the hand, and makes a sound when it meets the table that you notice the first week and miss afterwards. This is the piece of the range people end up using most, because it is the one that never leaves the counter.

Material & craftsmanship

Solid 78:22 kansa, cast right through and hand-finished to its final polish — no plating, no lacquer, no lining to wear away. Small variations in tone between glasses are normal and come from the hand-finishing. The rosette is laser-engraved into the metal at a consistent depth, so it will not wear off however often the glass is washed.

One or a pair

A glass of water is rarely poured for one. The pair is there because that is how these actually get used — two on a tray, two by the bed, two set out when someone comes over. The single is the right way to try kansa before committing to a set.

On the alloy

These glasses are made to the 78:22 kansa specification like everything else here. They have not themselves been through a lab. The elemental report on this site sampled a different melt — the one behind the children's set — and stretching that across the range would be exactly the kind of claim the rest of this site exists to avoid. Specification, then, not measurement. A report on this batch will appear when it is done.

Still being measured: capacity, height, weight each. Rather than print an estimate we leave the row out — message us and we will send the exact figures.

Care & use

  • Hand-wash only, with a mild dish soap and warm water; dry immediately with a soft cloth.
  • Water, milk and buttermilk are fine. Keep citrus and sour drinks out of it — see the FAQ below.
  • Pour and drink rather than store: do not leave a drink standing in it overnight.
  • Solid metal: never in the microwave, never on an induction hob, never over a flame.
  • A gradual darkening into patina is normal for bronze. Full care notes are on the kansa page.

FAQ

What can I drink from it — does nimbu pani count? +

Water, milk and buttermilk are what a kansa tumbler is for. Sour and citrus drinks are not: nimbu pani, kokum, aam panna, anything with lemon, tamarind or vinegar in it will react with the copper in the alloy, the same way an acidic curry does in a bronze bowl. Use glass or steel for those. And with anything, pour and drink rather than leaving it standing — a drink left in it overnight has hours to react, which is the one thing bronze genuinely dislikes.

Why is a pair cheaper than two singles? +

Because two is how these get used, and it is cheaper for us to pack and ship one parcel than two. The pair is ₹3,049 against ₹3,398 for two singles.

Is this the same tumbler as the one in the kids thali set? +

No. The kids set includes its own 120 ml tumbler, sized for a small hand and engraved with a giraffe. This is the adult glass, larger and carrying the lotus rosette. These are sold as adult drinkware.

Will it keep water cold? +

It takes the temperature of what is in it and holds it a while, the way any solid metal does — so cold water stays cold longer than it would in plastic, and the glass itself gets cold to hold. It is not insulated and it is not a flask.

Has this been assayed? +

No, not these. The report on the kansa page came from a sample of a different melt, and copying its numbers across would mean telling you something we have not checked. The specification is shared; the measurement is not. We would rather the page be thinner and true. A report on this batch is coming and will be published in the same form as the first one — figures first, whatever they show.
