Post Objects is a sculptural candle studio in Titirangi, on the western edge of Auckland, New Zealand. It was founded by Liz Wycherley and Simon Oosterdijk, whose first body of work, the Flow series, grew out of fluid simulations the two developed together. Liz, a ceramicist and former womenswear designer, now leads the studio.

Each form is cast by hand in wax and released in small editions, in series of three.

The studio has made work for SSENSE, Completedworks and Monument Gallery, London, whose opening was featured in Wallpaper* and Vogue.

Liz Wycherley on her process

I'm drawn to any process where the material takes its own path and I become more of an observer. When I'm in the studio I'm actively trying to connect to the pull a child feels to push the button, crack the egg, pop the bubble.

I'm never fully in control, and that's part of what I love. The material does what it wants to do and the ego and logical side is taken away. It makes room for me to enjoy the process as an observer instead of feeling the burden of making a form say a particular thing.

I have two preschoolers and they live this way 100% of the time. If they see a potato chip on the footpath you know it's getting stamped on. I'm really inspired by their connection with their instincts. I'm also really tired from protecting them from their instincts. For me, working in a way that puts me back into a state of freedom and out of parent mode feels like the right counterbalance. I feel like the more I practice it the more I'm able to trust my own instincts.

Working this way takes me out of the equation which gives me a nice distance from the forms. I think it also leaves something else open. I've noticed in people choosing one at my studio that the ambiguity of the forms definitely creates a sort of three-dimensional Rorschach test. It's so interesting to see which ones draw different people in and which repel. Their subjective forms make me feel a connection to something primal and archetypal. There's perhaps a link to the subconscious that I've seen affecting people. I've had people stand at the shelf in my studio for over an hour trying to feel which form is right for them. Finding the right one is very much about connecting again with instinct.

What I hope these works can do is communicate that feeling of visceral freedom to anyone holding them in their hand or looking at them on their shelf. Everyone has it in them. I find it really sad that adults are trained out of it, I guess it stops us hitting each other with sticks but it also leaves us feeling a bit dead inside. I'm interested in the curiosity and satisfaction side, less so in the crushing bugs side.

I read that Jung used to go down into his garden and work most days on a tiny village he was building with stones and mortar by the lakeside. He did it every time he felt stuck. I guess it's a bit like building a model railway, completely absorbing and seemingly pointless to an outsider, but I know I would feel huge satisfaction in it. I feel it too when I see someone pruning a bonsai, or cutting a perfect edge on their roadside lawn.

I'm a ceramicist but I chose wax for this candle experiment deliberately for its ability to change again once it's lit. I'm very discouraged by the idea of filling the world with stuff. It used to get to me working in clay that lasts for millennia. I love that wax can completely disappear. To me these forms feel more like an experience than an object. The freedom of the way they are made ties nicely for me into the way that they burn. Lighting a form releases it into a second joyful process. My hope is that you can see it in the forms: the energy of the material, still alive.

I'm doing these experiments for the sheer joy, and I hope that feeling translates to others from being with the forms. There's a lightness in the way they're made, and I love that about them. I like to think of them as little totems on your shelf, encouraging you to follow your strange creative impulse. I've seen them used as effigies, offerings and even fortunes. I love that people take their own path with them.

Material references for the Flow series: honey, lava and mud Material references for the Flow series: honey, lava and mud

1. The Flow series: how it’s made

We began by collecting material behaviours: honey folding into itself, lava cooling at its edges, mud pools bubbling. From these, we chose the ones that might hold as solid forms.

2. Setting up the simulation

The references were rebuilt in a fluid dynamics simulation. Rather than designing a shape, we set the conditions: should it spin as it falls, should the viscosity become unstable, should the surface tension be pushed higher?

3. Choosing what’s made

When a simulation looks promising, we test whether it can actually be produced. Will it release cleanly from a mould? Are there undercuts that make it impossible? Is it balanced enough to hold its shape?

4. Printing the master

The chosen form is printed in resin, layer by layer, then sanded and refined by hand. Every mark on this surface will be carried into every candle that follows.

5. Making the mould

The master is set in a custom 3D-printed mould box and silicone is poured around it. There have been leaks, blowouts and whole batches of silicone lost to the floor. The process is more controlled now, but never entirely certain.

6. Pouring the wax

With the mould ready, the wick is threaded and the wax is heated and poured. The room is held at a steady temperature so the form sets cleanly. It’s a simple step on paper, but wax has its own behaviour, and we adjust as we go.

7. Demoulding

The first demould of a new form is always tense; after that, it becomes our favourite part. The mould is peeled back slowly, in the hope the form releases in one piece. If it doesn’t, we start again.

Each piece is trimmed, checked and refined. The wick is cut and the base finished. A final burn test comes before it becomes a finished object.
