A material with a thousand years of history
Porcelain is one of the oldest and most trusted materials in ceramics. It has been used to make teaware for over a thousand years, and the reason is simple: it does the job exceptionally well. Smooth, dense, non-porous, and fired to a bright white finish, porcelain keeps tea tasting exactly as it should while holding up to daily use without fuss.
Unlike fine bone china, porcelain contains no bone ash. Its strength comes entirely from the blend of kaolin clay, feldspar, and silica, fired at very high temperatures of up to 1,450°C. This process, called vitrification, transforms the raw materials into something that is fully fused, glass-like in its density, and highly resistant to absorbing liquid or holding flavour.
Porcelain vs fine bone china: what's the actual difference?
It's a question worth answering directly, because the two are often confused. Porcelain fires to a brighter, cooler white. Fine bone china has a warmer, more ivory tone with a subtle translucency. Porcelain is slightly heavier and more durable in everyday use. Fine bone china is lighter and more luminous. Both are non-porous, both are excellent for tea, and both are considerably better than the average mug most people start out with.
If you are choosing between them, think about feel and context. Porcelain suits everyday use well. It is resilient, consistent, and holds its finish over time. Fine bone china is the choice when you want something that feels like an occasion every time you use it.
How T2's porcelain is made
The process begins with the raw materials being finely ground and combined with water to form a workable body. Shapes are formed by wheel throwing, jiggering, or slip casting depending on the piece. Cups and plates are typically jigger-formed for consistency, while teapots and more intricate shapes are slip cast using liquid clay poured into plaster moulds.
After forming, the pieces are bisque fired at a lower temperature to strengthen them before glazing. The glaze, a mixture of silica, alumina, and water, is applied by dipping, pouring, or spraying and can be adjusted to create glossy or matte finishes. The final firing at up to 1,450°C vitrifies the body completely, creating the smooth, bright, durable result.
Decoration comes after: hand-placed decals, sprayed finishes, or gold and platinum hand-painting, followed by a third low-temperature firing that fuses the design permanently into the glaze.
Why it's well suited to tea
Porcelain's neutrality is one of its great strengths for tea. The non-porous surface means it does not absorb flavour or aroma between brews, so a morning black tea does not ghost into an evening herbal. The bright, clean interior also shows the colour of the tea clearly, which matters more than most people realise until they start paying attention to it.
The material also retains heat well, which keeps your tea at the right temperature for longer without needing to rush the cup.
Caring for your porcelain
Most plain porcelain is dishwasher safe, though handwashing is always the gentler option and will extend the life of the finish. Use mild detergent and avoid abrasive tools. As with all ceramics, avoid sudden temperature changes as moving a piece directly from very hot to very cold water can stress the material over time. Porcelain with metallic detailing should be handwashed and kept out of the microwave.
A note on porcelain's origins
Porcelain originated in China during the Tang dynasty and was refined over centuries in Jingdezhen, a city that became known as the world's porcelain capital. When it first reached Europe in the 17th century it was so rare and desirable it was called "white gold". For Kiwis, that history is a reminder that what might look like a simple everyday cup is actually the product of over a thousand years of accumulated craft knowledge. A well-made piece of porcelain is worth looking after.
One thing to listen for: a good piece of porcelain, when tapped gently, rings with a clear bell-like tone. It is a small test that potters and collectors have used for centuries to distinguish quality pieces.
