Tin (suzu) 錫

What is Japanese tin (suzu)?

Tin is a chemical element, a soft and malleable metal with the symbol Sn. At room temperature it has a silvery-white appearance, resists corrosion from water, and can be highly polished. In Japanese tableware, Nousaku calls the material suzu and uses 100 per cent tin rather than hardening it into an alloy.

The useful starting point is that tin is the material itself rather than a silver-coloured finish laid over something else. Its softness is part of the appeal, and also the reason a tin cup needs a little more care than a harder vessel.

Why is tin used for drinking vessels?

A drinking vessel puts its material right against the drink, so the surface and the way it handles heat both matter. Nousaku describes pure tin as significantly antibacterial and suitable for serving food, and says it resists rust and tarnish easily enough for tableware.

The taste claim is a traditional one, and it is worth keeping it in that lane. Nousaku says tin has long been said to enhance the flavour of sake. Its FAQ also says a tin cup makes young red wine richer and mellower, and gives beer a creamier head from the rough surface left by the mould. Those are the maker's serving observations rather than a guarantee that every palate will read the same drink in the same way.

Temperature is more straightforward. Tin conducts heat, so a cup made from it quickly gives you the temperature of what is inside rather than insulating the drink from your hand. A chilled drink makes the cup feel cold; a warm drink travels into the cup quickly. Nousaku allows a short refrigerator chill, but the care limit is no more than 30 minutes and never the freezer.

Why does 100 per cent tin bend?

Pure tin is soft and malleable. Nousaku says tin is normally mixed with other metals to increase hardness, but its tableware uses 100 per cent tin so the material can be bent or stretched by hand. That is why a flexible tumbler or a shallow plate can be given a small curve instead of staying fixed in one shape.

The maker's best-known example is the Kago basket, a flexible tin basket built around the same property. It is useful background on the material; we do not currently list it. When tin is bent, it can make a crackling sound called tin cry. Make one gentle adjustment when you reshape an item, then leave it alone. Repeatedly working the same point eventually tears the metal, and a stretched piece will not perfectly return to its first shape.

Tin plate versus solid tin: what is the difference?

Tinplate, usually written as one word, is steel sheet coated with a thin layer of tin. The tin helps protect the steel from rust, but the body of the object is still steel. Solid tin means tin is the material making up the object itself, rather than a steel body with a tin skin.

That difference matters when you are reading a product description. A pale metallic surface does not prove that a piece is solid tin. Look for the maker's material statement. Nousaku describes the tableware in this range as 100 per cent tin, which is a different construction from tinplate.

How do you look after tin?

Hand wash tin with mild detergent and a soft sponge. Dry it after washing so water does not sit on the surface. If the shine dulls, Nousaku recommends a common metal polish, toothpaste, or a paste of baking soda. Keep abrasive materials, wire wool and brushes away from it because they can scratch the surface.

Keep tin out of the dishwasher and drying machine. Never put it in a microwave or over a flame: the metal has a low melting point. A brief refrigerator chill is allowed by the maker, up to 30 minutes, but never use the freezer.

If a cup or plate has been flexed, ease it back toward the shape you want with a small, gentle movement. Do not force it and do not keep bending the same crease. Nousaku also says a white mark can be a casting characteristic caused by temperature changes, so not every pale mark is a water spot.

Where does tin sit on our shelves?

As of 2 September 2026, we list 21 Nousaku products: six vases, four incense stands, three beer cups, two tumblers, two sake cups, one sake pitcher, one bamboo leaf plate and two chopstick rest sets. We also list one Kousaido tin incense stand. Published listings can sell through, so check the individual listing when you are ready to order.

Start with the Nousaku collection. For the drinking pieces, see our sake cup guide; for the two tin rest sets, see the chopstick rest guide; and for the incense stands, see the incense holder guide. We keep Nousaku's company and Takaoka context on the Nousaku maker page.

Quick answers

These are the questions people ask us most often about tin, answered briefly.

What is tin, or suzu? Tin is the chemical element Sn, a soft, malleable metal; Nousaku calls it suzu and uses 100 per cent tin in its tableware.

Why does pure tin bend? Pure tin is soft and malleable, so it can be bent or stretched by hand. Repeatedly bending the same point can tear it, and a stretched piece will not perfectly return to its first shape.

Does tin change the taste of a drink? Nousaku says tin has long been said to enhance sake flavour, and that young red wine tastes richer and mellower in a tin cup. Treat that as the maker's serving claim rather than a promise for every palate.

Does tin keep a drink cold? Tin conducts heat, so a cup quickly feels the temperature of its drink rather than insulating it. For chilling, Nousaku allows no more than 30 minutes in the fridge and no freezer.

How do you remove water spots from tin? Dry it after hand washing; if the surface is dull, use common metal polish, toothpaste or a paste of baking soda. Avoid abrasives, wire wool and brushes. A pale white mark can also be a casting characteristic caused by temperature change.

Can tin go in the dishwasher or over a flame? No. Hand wash with mild detergent and a soft sponge. Keep it out of dishwashers, drying machines and microwaves. Never put it over a flame.

Is tin plate the same as solid tin? No. Tinplate is steel sheet with a thin tin coating; a solid-tin object uses tin as its material rather than a steel body with a tin skin.

Do you carry the Kago basket? No. Kago is Nousaku's flexible tin basket and a useful example of why pure tin bends, but as of 2 September 2026 our range includes tableware, vases, incense stands, rests and related pieces rather than Kago.
