Teapots and brewing vessels
A teapot is a heat-retention decision wearing a decorative disguise. Pick for how long your tea sits.
The first thing to be clear about is that you do not need one. A mug and a basket makes the same tea. A teapot is for serving more than one cup — either to more than one person, or to yourself across an afternoon — and that single distinction should drive the whole purchase.
Once you accept that, the material question stops being about looks and becomes about how long the tea has to stay hot. Glass loses heat fastest. Ceramic and porcelain sit in the middle. Cast iron holds it longest — Primula publishes up to an hour for its enamelled pots, which no glass vessel approaches.
Glass: for watching, and for knowing
Glass teapots exist because loose-leaf tea is interesting to look at, and that is a completely legitimate reason to own one. There is a practical benefit too: you can see the color of the liquor, which is the fastest way for a beginner to learn what a two-minute steep looks like versus a four-minute one.
The catch is thermal. A glass pot on a table cools quickly, so the third cup is noticeably cooler than the first. And glass has a safety line that matters: most glass teapots are not stovetop vessels. Hario states plainly that its ChaCha Kyusu is safe for hot water, microwave and dishwasher but not for the oven, an induction hob or an open flame. Assume that is true of any glass pot unless the maker explicitly says otherwise.
Cast iron: for the long afternoon
Cast iron is the heat-retention answer and there is one distinction that decides everything about living with it. Enamelled cast iron has a glass lining: no seasoning, no rust, wash and dry normally. Bare cast iron, the traditional tetsubin, must be dried immediately every time or it rusts, and it develops a mineral patina that many people specifically want.
For a first cast-iron pot, buy enamelled. The traditional one is a commitment to a maintenance routine, and it is a much better second purchase than a first.
Neither is a kettle. Cast iron teapots are brewing vessels and most are explicitly not for the hob. Boil water separately and pour it in.
Gaiwan: the cheapest thing that teaches you the most
A gaiwan is a lidded bowl you brew in and pour from, using the lid as a gate. It is usually the least expensive vessel in any tea shop and it is the one we would push a curious beginner towards, because it makes short repeated infusions easy.
That matters more than it sounds. A three-minute mug steep averages a tea's whole character into one flavor. Four thirty-second infusions from a gaiwan show you that same tea changing, and that is the fastest way to work out what you actually like. There is no mechanism, no filter and nothing to replace.
Sizing, which is where the regret happens
Buy for the number of people who will actually drink. A 700 ml pot is right for two or three; a 300 ml pot is one generous mug. A half-filled large pot cools faster and brews worse than a filled small one, so the biggest pot is rarely the safest choice.

Guides and comparisons
Gaiwan vs teapot
A gaiwan is for tasting a tea properly; a teapot is for serving one. Buying the wrong one is a mismatch of purpose, not quality.

Stovetop-safe teapots: how to check before you crack one

Questions
Can a glass teapot go on the stove?
Usually no. Hario states its ChaCha Kyusu is not safe for the oven, an induction hob or an open flame, and that is typical. Some borosilicate pots are sold as stovetop safe; treat that as a claim to verify on the specific listing, never an assumption.
Is cast iron better than glass for tea?
Better at holding heat, worse at everything visual. Primula publishes up to an hour of heat retention for its enamelled cast iron. If your tea sits on a table for an afternoon, cast iron. If you want to see the leaves, glass.
What is a gaiwan and do I need one?
A lidded bowl you brew in and pour from. You do not need one, but it is usually the cheapest vessel in the shop and it makes short repeated infusions easy, which is the fastest way to learn what a tea actually tastes like.
What size teapot should I buy?
Match the number of drinkers, not the ambition. Around 300 ml is one large mug, 700 ml serves two or three. A half-full pot cools quickly and is a worse cup than a full smaller one.
