When you pour your morning coffee, the mug you reach for matters more than you'd think. It's the thing you hold every day. Here's what actually separates a handmade ceramic mug from a mass-produced one, from someone who makes them.
How mass-produced mugs are made
Most mugs on supermarket and department store shelves come out of factories that make tens of thousands a day. The clay is pressed or poured into moulds by machine, often under high pressure, then trimmed by machine and glazed by spraying or dipping on a production line. Firing happens in tunnel kilns that run around the clock, with mugs moving through on carts. Colour and pattern usually come from a single uniform glaze or a printed decal applied on top.
The result is consistent, cheap and perfectly fine for drinking from. It's also identical to every other mug in the batch, and nobody along the way decided anything about that particular mug.
How I make mine
My mugs are slip cast, which sounds like the factory method, and the principle is the same: liquid clay poured into a plaster mould. The difference is everything around it. I designed every mug shape myself and made each mould by hand in my studio in Bellambi. I mix the casting slip, pour each mug one at a time, judge when to take it out of the mould, then trim and finish every one by hand.
Then comes the part no machine does: glazing. I brush my own glazes on by hand, in layers, and the layers pool and run into each other in the kiln. Every mug goes through two firings, the second to cone 6, around 1220°C, which turns the clay into tough, non-porous midfire stoneware.
1. Every mug is one of a kind
Because the glaze is brushed on by hand and moves in the kiln, no two of my mugs come out the same. Two mugs from the same batch, in the same colourway, will still have their own drips, blends and colour breaks. A factory glaze line exists to remove exactly that variation. With a handmade mug, the variation is the point.
2. The colours are developed in the studio
Mass-produced colours are chosen to sell in volume. Mine come from months of glaze testing: mixing, layering and re-testing recipes until the colour is right. That's why my colourways have names, not product codes, and why they rotate as I develop new ones.
3. Made to be used, every day
A handmade mug shouldn't be too precious to use. Mine are food safe, and dishwasher, microwave and oven safe. The one habit worth keeping with any ceramic is to avoid sudden temperature changes, like filling a mug straight from the fridge with boiling water.
4. Small batches, made locally
Every mug is made by me, in my studio just north of Wollongong, in small batches. There's no production line, no overseas shipping container and no warehouse of unsold stock. Buying handmade supports a local maker and the craft itself, rather than volume and margins.
5. A mug you'll actually keep
Factory mugs are easy to replace, so they're easy to throw away. A handmade mug tends to become your mug: the one you reach for first, the one you notice when someone else is using it. Well-fired stoneware lasts for decades, so it's worth choosing one you love.
So which should you buy?
If you need a dozen matching mugs for the office kitchen, a mass-produced set does the job. If you want a mug you'll enjoy holding every morning, made by a person who decided every detail of it, handmade is worth it. You can browse all my handmade ceramic mugs and cups, or go straight to mugs, cups or espresso cups.

Frequently Asked Questions
What is the difference between a handmade mug and a regular mug?
A regular mug is made by machine in large numbers, and every one is identical. A handmade mug is shaped, finished and glazed by a person, so each one is slightly different. Mine are slip cast in moulds I designed, then trimmed and brush-glazed by hand, so no two are the same.
Why are handmade mugs so expensive?
Because of the time and hands involved. Each of my mugs is poured, trimmed, glazed and fired twice by me, and the glazes are developed over months of testing. A factory spreads its costs over tens of thousands of mugs a day; a small studio can't. My mugs are $65 to $70, cups $38 and espresso cups $21.
Why do handmade mugs have a rough bottom?
The base of a mug is left unglazed so it doesn't fuse to the kiln shelf during firing. That bare ring of clay is the natural texture of the stoneware, and it's a sign the mug was fired properly, not a flaw.
What clay is used for handmade mugs?
It varies by potter. I use cone 6 midfire stoneware slip casting clays, which fire to a strong, non-porous body that's food safe and suits everyday use.
Can you put hot liquid in a handmade ceramic mug?
Yes, that's what it's made for. The only thing to avoid is a sudden temperature change: if a mug has come out of the fridge, let it sit on the bench for a minute, or warm it with a splash of warm tap water, before filling it with boiling water.
