What I learned Day One about wedging clay.
I Learn to Wedge Clay
Day one I learn to wedge.
The studio smells faintly of damp earth and kiln dust, that unmistakable perfume of clay that clings to everything: tables, aprons, shoes, even the air. Around me, other students are unpacking their first lumps of clay, some with excitement, others with the quiet concentration of people about to try something they’ve only seen in videos. I’ve been waiting for this moment—the wheel, the spin, the transformation of a lump into a vessel.
But before I can even touch the wheel, my instructor slides a lump of clay onto the table in front of me and says, “First, you wedge.”
I look down at the clay. It’s heavy, solid, and—at least to my eye—perfect. Why knead what already looks ready? But my teacher insists. She presses the clay forward, folds it back, and repeats the motion with an ease that makes it look like second nature. “This,” she explains, “is where the work begins. Step one. Wedging prepares the clay for the wheel.
So I try. My first attempts are clumsy. I push too hard, fold too quickly, and slam the clay onto the table with more force than finesse. Still, I keep going. Press, fold, roll. Press, fold, roll. How do I know when to stop? Did I do this enough? Seems right and I am eager for the wheel.
I center it—more or less—and begin pulling the walls upward. For a few glorious seconds, I think I’ve succeeded. Then, beneath my fingertips, I feel it: a soft pop. An air bubble bursts through the surface, leaving behind a crater. Another bubble follows. My walls weaken, wobble, and slouch. I lose control of the clay, it catches my finger and the wall folds over on itself.
That’s when I realize: it isn’t enough to wedge. You have to wedge well.
Why Wedging Matters
Clay is trickier than it looks. Even fresh from the bag, it can hide little inconsistencies: air pockets from the manufacturing process, uneven moisture where the outer layers have dried more than the center, or misaligned clay particles that make the body less cooperative. Left alone, these imperfections show up at the worst possible moment—while throwing, while drying, or even in the kiln.
Wedging is the potter’s insurance policy. Done properly, it compresses the clay, evicts air bubbles, evens out moisture, and aligns the microscopic plate-like particles that give clay its strength. It doesn’t just make the clay workable—it makes it trustworthy.
But here’s the part I learned the hard way: bad wedging can actually add air instead of removing it. Push too far, fold too randomly, or rush through the process, and you’ll trap pockets instead of smoothing them out. That’s why wedging isn’t about brute strength—it’s about rhythm.
My First Attempts
Those first few days, I was determined to get it right. I watched my teacher’s hands closely, trying to mirror her motion. She used the ram’s head method, pressing the clay forward and down, then folding it back toward her in a smooth, rolling motion. Each repetition left a little curl on the surface, a layered shape like the horn of a ram.
I, on the other hand, looked more like I was punching the clay into submission. My curls were jagged, uneven, or nonexistent. Sometimes I’d fold the clay in such a way that a bubble actually puffed out along the surface—proof that I’d tucked air in instead of working it out.
Still, I kept practicing. Slowly, my hands began to find the rhythm. Press, fold, roll. Not too fast, not too hard. The clay started to feel different under my palms—more cohesive, more solid, less rebellious.
One day, I finally carried a properly wedged lump to the wheel. I centered it, pulled the walls, and—miracle of miracles— no pops. No sudden craters. Just smooth, even walls rising in rhythm with the wheel.
That was the moment wedging stopped feeling like a punishment and started feeling like a promise.
When to Wedge Clay
By now, I wedge almost everything. Fresh clay straight from the bag? A few quick turns to balance the moisture. Clay that’s been sitting overnight? Definitely needs it. Reclaimed clay, the scraps I save and rehydrate? That clay has lived a life, and it always gets a thorough wedging before I trust it again.
Wedging is like checking your mirrors before driving. Could you skip it? Sure. Will things probably go wrong if you do? Absolutely.
And here’s something else I lea rned: the time you spend wedging is always less than the time you’ll spend fixing problems later. It’s far easier to roll air bubbles out of a lump at the wedging table than to fight them on the wheel.
How Poor Wedging Adds Air Bubbles to Clay
When I rushed through the process, I thought I was saving time. Instead, I was actually trapping air inside. That’s the cruel trick of bad wedging — it doesn’t just fail to remove air bubbles; it can create them.
On one memorable attempt, I cut my cla y block in half with a wire just to check. There they were: tiny pockmarks scattered like stars across a night sky. Beautiful, maybe, but problematic while throwing.
That day I learned the difference between wedging because you have to and wedging until it’s done right.
How Wedging Cl ay Prevents Air Bubbles and Cracks
The science behind it is straightforward. Clay particles are flat platelets, a bit like a bag of Chex Mix. Left alone, they lie at random angles. Wedging coaxes them into alignment, making the clay stronger and more plastic. At the same time, those sneaky little air bubbles get squeezed to the surface and worked out.
The result is clay that centers more easily, stretches evenly on the wheel, and dries without surprise cracks. Once I started wedging properly, I noticed the difference immediately: fewer wobbles, fewer collapses, and no surprises.
How to Wedge Clay: The Two Main Styles
Though this isn’t a tutorial in the strictest sense, my story would be incomplete without mentioning the two main wedging techniques.
The first, the ram’s head wedge, is the beginner’s best friend. You press forward and down, folding the clay over itself, then pull it back toward you. Over and over, until the clay takes on that telltale layered horn pattern. It’s straightforward, forgiving, and perfect for small to medium lumps.
The second, the spiral wedge, is more advanced. It involves the same forward press, but with a twist added to each motion. The clay gradually spirals into a conical swirl, aligning particles in a way that gives extra strength. It’s efficient and elegant, especially for larger lumps, but it feels awkward at first—like trying to dance with someone who doesn’t know the steps.
I didn’t attempt spiral wedging for quite some time. In fact it is a process I rarely use. It feels more like a right of passage to show off your skill as a potter. But, I understood why so many potters love it. The motion feels smooth, almost like rolling the clay into a wave. But whether ram’s head or spiral, the key is the same: rhythm, patience, consistency.
The Secret Meditation of Wedging
At first, wedging was just another step between me and the wheel. Something I had to do, but didn’t want to. Over time, it became something else entirely.
There’s a meditation in it. The steady thump of clay against the table sets a rhythm, a grounding beat. My breath syncs with the motion: inhale on the press, exhale on the fold. The process and rhythm focuses your brain to the task ahead. By the time the clay is ready, I feel calmer, more focused, ready to work.
Now, when I arrive in the studio, wedging is how I settle in. It’s not wasted time—it’s the reset button. The clay gets what it needs, and so do I.
Lessons the Clay Taught Me
Looking back, I’m grateful f or that day-one disaster with air bubbles. If the clay had behaved for me the first time, I might never have learned the importance of wedging properly. Clay has a way of humbling you quickly, and every mistake is also a lesson. It will teach you with a wonky wall, or an uneven rim.
Day one I learned to wedge, and I learned to wedge poorly. But that mistake taught me the most important lesson of pottery: every step matters. Proper wedging isn’t glamorous, but it’s the difference between frustration and success, between a collapsed mug and a vessel that stands proudly on the shelf.
Now, whenever a new student asks me why we bother wedging, I tell them my day-one story. How I thought I’d done everything right, only to discover I’d made things worse. How I learned that wedging is about rhythm, not force. How I discovered that the time I spend at the wedging table is never wasted.
Wedging, I tell them, is where the conversation with clay begins. It’s not just preparation for making. It is making. The first step, the grounding ritual, the quiet promise that if you take care of the clay, the clay will take care of you.
And that’s why, no matter how many years pass, I always start the same way: with a lump of clay, a steady rhythm, and the memory of day one, when I first learned to wedge.
