The best glass teapots
You buy glass to watch the leaves. You check the safety statement so the pot survives the first month.
We earn a commission if you buy through the links on this page, at no extra cost to you. It does not change which products we name or what we say about them — how this is funded.
Buy the HARIO ChaCha Kyusu Maru. Borosilicate glass pot and lid, a stainless strainer, three published capacities, and a maker who states in writing that it is safe for hot water, microwave and dishwasher and not safe for the oven, an induction hob or an open flame. That last sentence is worth more than any design feature in this category.

HARIO ChaCha Kyusu Maru Tea Pot
Borosilicate glass with a full-width stainless basket, in three sizes. The clearest published spec sheet of any teapot here.

What the numbers mean
The large strainer is the functional argument. A wide basket lets the leaves open across the whole pot rather than packing into a tube, which is the single biggest difference between teapots at this price.
The explicit not-for-stovetop line is the reason we point at this one. Glass teapots get put on hobs and crack, and Hario states plainly that this is not a stovetop object.
Three capacities matter more than they sound. 300 ml is one generous mug; 700 ml is a pot for two or three people. Buying the wrong one is the most common teapot regret.
Good for
- Wide strainer that lets leaves expand
- Microwave and dishwasher safe, both published
- Three sizes, so you can match your actual household
Against it
- Glass loses heat faster than ceramic or cast iron
- Not for the hob, the oven or a flame
- Glass shows tea staining if you leave it wet
Skip it ifSkip it if you want the pot to stay hot for a second and third cup. Glass is the worst insulator here; cast iron is the best.

Pick 2 · Stopping the brew at the right moment
Bodum Assam Glass Tea Press
A press, not just a pot. Plunging drops the leaves below the filter and ends the extraction, which is the problem every teapot has.
Published specifications
- Capacity
- 34 oz, serves 3 to 4Source: Target — Bodum 34oz Assam Tea Press listing
- Body
- Borosilicate glassSource: Target — Bodum 34oz Assam Tea Press listing
- Filter
- Stainless steel basketSource: Target — Bodum 34oz Assam Tea Press listing
- Care
- Dishwasher safeSource: Target — Bodum 34oz Assam Tea Press listing
What the numbers mean
The plunger is the design answer to over-steeping. In an ordinary teapot the leaves keep working while the pot sits on the table, and cup three is bitter. Here you plunge at three minutes and cup three tastes like cup one.
It is a tea press, not a coffee press, and the filter reflects that — but the same object will make coffee badly if you ask it to, which is worth knowing if counter space is tight.
34 oz is a table pot. For one person it is oversized, and a half-full press cools quickly.
Good for
- Extraction stops when you decide it does
- Genuinely dishwasher safe, unusual at this price
- Serves three or four without a refill
Against it
- Glass, so it cools fast and breaks if dropped
- Plunger mechanism is another thing to clean
- Too big for a single drinker
Skip it ifSkip it if you brew one mug at a time. A 34 oz press half-filled is a worse cup than a 300 ml pot filled.

Pick 3 · A first teapot on a budget
Sweese Glass Teapot with Infuser
The cheap end of the glass-and-basket format. Works, and the money you save buys a lot of tea.
Published specifications
- Capacity
- Not verifiedSold in several sizes; we have not verified a figure from the maker.
- Stovetop safety
- Not verifiedSome Sweese pots are sold as stovetop safe and some are not. This is the one spec you must read on the listing itself — a glass pot on the wrong hob cracks.
What the numbers mean
The format is proven; this is just an inexpensive execution of it. Glass body, stainless basket, lid.
The stovetop question is the one that actually matters and it varies by model, which is why we flag it rather than answer it. Never assume a glass teapot can go on a hob.
We have not verified published specifications from the maker, so this is a budget category recommendation rather than a model endorsement.
Good for
- The cheapest way into the glass-and-basket format
- Basket infuser rather than a narrow tube
- Widely available
Against it
- No verified published specifications
- Stovetop safety varies by model
- Thin glass cools quickly
Skip it ifSkip it if you want the version with a published spec sheet. The Hario ChaCha tells you exactly what it is and what it is not for.
Why glass at all
Two reasons, and the second is more practical than it sounds.
The first is that loose-leaf tea is genuinely nice to look at while it brews. That is a legitimate reason to buy an object and we are not going to be sniffy about it.
The second is that you can see the color of the liquor, and color is the fastest feedback loop a beginner has. Watching a green tea go from pale straw to deeper yellow over ninety seconds teaches you more about steep timing than any chart, including ours.
Borosilicate is the spec to look for
Borosilicate glass contains boron oxide, which gives it much greater resistance to thermal shock than ordinary soda-lime glass. That matters when you pour water at 212F into a pot that has been sitting at room temperature.
Hario publishes heatproof borosilicate for the ChaCha's pot and lid and notes the glass has been treated to resist shattering. The Bodum Assam listing publishes a borosilicate body. If a glass teapot's listing does not say borosilicate, assume it is not.
The stovetop line, stated plainly
Most glass teapots are not stovetop vessels. Borosilicate resists thermal shock; it does not survive direct flame or the localized heating of an induction hob. Hario says so explicitly for the ChaCha, and that explicit statement is what a good listing looks like.
Some borosilicate pots genuinely are sold as stovetop safe. Treat that as a claim to verify on the specific product page, never an assumption carried over from another pot. Our stovetop-safety guide goes through how to check.
The thermal trade-off nobody mentions
Glass is a poor insulator. A glass pot on a table cools noticeably between the first cup and the third, and that is the cost of being able to see through it.
| Material | Holds heat | Shows the leaves |
|---|---|---|
| Glass | Least | Yes |
| Ceramic / porcelain | Middle | No |
| Cast iron | Most — Primula publishes up to an hour | No |
If your tea sits on a table for an afternoon, that difference is real and cast iron is the honest answer. If you drink a pot in twenty minutes, it does not matter and glass wins on everything else.
Cleaning and staining
Glass shows tea staining that ceramic hides, and the fix is simply rinsing it out rather than leaving it wet with leaves in overnight. Hario publishes that the ChaCha is dishwasher safe with the strainer removed before microwaving; the Bodum listing publishes dishwasher safe.
For a stained pot, a soak in dilute bicarbonate of soda lifts most of it. No abrasives — a scratched glass pot stays scratched.
How we picked
Published glass type first, published safety limits second, strainer geometry third, capacity fourth. Where a maker publishes nothing, the card says so and the pick ranks below the ones that do. The full method is on how we pick.
What we did not do
We have not poured boiling water into any of these pots, thermally shocked one, or dropped one. No durability testing happened here, and any page claiming otherwise about a glass teapot should be asked how.
Questions
Are glass teapots good for loose-leaf tea?
Yes, provided the strainer is wide enough for leaves to expand. Glass also lets you see the liquor color, which is the fastest way to learn what a good steep looks like. The trade-off is that glass loses heat fastest.
Can glass teapots go on the stove?
Usually not. Hario states its ChaCha Kyusu is not safe for the oven, an induction hob or an open flame, which is typical. Some borosilicate pots are sold as stovetop safe — verify it on that specific product page.
What is borosilicate glass and why does it matter?
Glass containing boron oxide, which resists thermal shock far better than ordinary glass. That matters when you pour near-boiling water into a room-temperature pot. If a listing does not say borosilicate, assume it is not.
How do you clean a stained glass teapot?
Rinse it out after use rather than leaving wet leaves in overnight. For existing stains, soak in dilute bicarbonate of soda. Never use abrasives — scratches in glass are permanent.
