Tea Comparisons

Your teapot matters more than most people think. It affects how long the tea stays hot, how pure it tastes, how easy it is to clean, and how much you enjoy making tea at all. The two most popular materials for good teapots are ceramic and glass, and using them feels quite different.

Here's a practical comparison to help you choose.

Heat retention: ceramic wins

This is the biggest practical difference. Ceramic, especially thick-walled stoneware or porcelain, holds heat much better than glass. Depending on how thick and heavy it is, a ceramic teapot can keep tea at drinking temperature 15 to 20 minutes longer than a similar glass one.

If you brew a pot and pour cups over 20 to 30 minutes, ceramic keeps the later cups warm without a tea cosy or warmer. If you brew and drink straight away, it matters less.

Glass heats up fast and cools down fast. That's no problem for a single cup you drink within minutes, but it's a real drawback when you're sharing a pot over a long conversation.

Watching the tea: glass wins

This is why glass has such loyal fans. Watching loose leaf tea steep is very calming: the leaves open up, the colour deepens from amber to dark mahogany, and the leaves drift slowly down as they sink. For a lot of tea drinkers, seeing all this is part of why they moved from bags to loose leaf in the first place.

Glass is especially rewarding with teas that change a lot as they steep. Nepali oolongs start as tightly rolled balls and open into full leaves over several steeps. White teas' silver buds slowly release their colour. And with any whole-leaf black tea, you can judge the steep by its colour instead of the clock.

With ceramic, you see none of that. You pour in the water and wait. That's fine if you're only after the drink, but some people feel it takes something away.

Flavour: both are excellent

Good ceramic (porcelain or glazed stoneware) and borosilicate glass are both essentially flavour-neutral. They don't leach anything into the tea or hold on to flavours between brews.

The exception is unglazed clay, like Yixing clay from China, which is meant to interact with the tea. It soaks up tea oils and seasons with use, subtly changing the flavour. Enthusiasts see that as a feature, not a flaw, but it does mean you should usually keep an unglazed clay pot for one type of tea.

If you're using glazed ceramic or glass, neither will change how your tea tastes.

Durability: ceramic usually wins

A well-made ceramic teapot can last for decades. It can take the odd knock without shattering, and many become treasured objects that pick up a patina of tea stains and more character as they age.

Borosilicate glass handles sudden temperature changes much better than ordinary glass, so you can pour boiling water straight in without it cracking, but it's still glass. A sharp knock against a tap or countertop is more likely to chip or break a glass teapot than a ceramic one. Treat it with reasonable care and it will last; drop it once at the wrong angle and it won't.

Cleaning: glass is easier

With glass, you can see at a glance whether the pot is clean. Tannins stain both materials over time, but stains show straight away on glass and hide on ceramic. Oddly, that means glass owners tend to notice and clean stains sooner, while ceramic owners may not notice until the staining is heavy.

Both clean up the same way: warm soapy water every day, a paste of baking soda for tannin stains, and an occasional soak in white vinegar for mineral build-up. Don't use abrasive scrubbers on either, because they scratch the surface and leave places for bacteria to hide.

Price: about the same

Both come at a wide range of prices. Basic glass teapots start at around CAD $20 to $30, and good borosilicate pots with an infuser basket cost $40 to $80. Ceramic starts at a similar price and goes higher for hand-thrown artisan pieces. At the same level of quality, neither is reliably more expensive.

Which should you choose?

Choose glass if you brew and drink straight away, you like watching the tea steep, you drink green or white teas where the colour helps you time the steep, or you want a pot you can easily see is clean.

Choose ceramic if you brew a pot and share it over 30 minutes or more, you want the tea to stay hot without a warmer, or you like the feel and look of traditional teaware.

Either way, pick a size that fits how you actually brew. A 400ml pot is right for one person, and an 800ml to 1L pot is better for sharing. An oversized pot that you only half fill loses heat faster and makes it easy to over-steep.

Frequently Asked Questions

Does the teapot material affect the taste of tea?
Glazed ceramic and borosilicate glass are both flavour-neutral and won't change the taste. Unglazed clay (like Yixing) seasons over time and subtly changes the flavour, which is the point in that tradition.

Can I put a ceramic teapot on the stove?
Most ceramic teapots aren't made for direct heat. Use them only for brewing and heat your water separately in a kettle. Some cast iron teapots can go on the stove, but that's a different material altogether.

How do I remove tea stains from a teapot?
Mix baking soda with warm water into a paste, spread it on the stains, leave it for 15 to 20 minutes, and rinse. For stubborn stains, soak the pot overnight in one tablespoon of white vinegar per cup of warm water.

What size teapot do I need?
For one person, 300 to 450ml. For two, 500 to 700ml. For 3 to 4 people, 800ml to 1.2L. A pot that's too big for the occasion keeps the tea at brewing temperature longer than you need and risks over-extraction.

Is glass teaware safe for boiling water?
Ordinary glass isn't; sudden heat can crack it. Look for borosilicate glass, which is heat-resistant and safe with boiling water. Most glass teapots sold for tea are borosilicate, but check before you buy if you're not sure.
