Every journey From Clay to Cup begins the same way with a cool, heavy lump of earth in your hands. At first, it doesn’t look like much. But inside that mass of minerals and moisture is potential waiting for touch, patience, and heat.
Good clay feels a little sticky, but not wet. Most studio-grade clay used in pottery cafés has about 2224% moisture, which makes it flexible enough to shape yet stable enough to hold its form. When it’s too dry, it cracks; too wet, and it collapses.
At our studio, we often remind beginners: clay remembers everything you do to it. Every press, twist, and correction gets recorded in its texture. That’s why centering it properly on the wheel the very first motion in pottery is like finding balance before creativity.
Tip.
To center clay faster, start at medium wheel speed (around 80 rpm). High speed might look fun, but it usually sends your clay flying instead of forming.
The Creative Journey in Six Touchpoints
Each stage turns raw earth into something that holds warmth, texture, and memory.
Moisture level for perfect workability; too dry cracks, too wet collapses.
Tiny fingertip shifts affect wall thickness; rhythm matters more than speed.
At 60–65% humidity and 20–24°C to prevent cracking and warping.
Clay turns ceramic, shrinking ~9%. The first irreversible transformation.
Liquid glass fuses into shine; oxygen levels define final hue depth.
Balanced, watertight, and warm — shaped by patience, fire, and touch.
Shaping the Form
When the wheel starts spinning, most people expect a peaceful experience and it often is but technically, it’s all about balance and rhythm.
The From Clay to Cup process requires small, steady pressure. Even a one-millimeter change in your fingertip can shift the wall thickness by 0.1 mm, which is enough to affect drying and firing later.
Professional potters sometimes say, “Don’t fight the clay.” They mean it literally. Clay responds best to consistent motion. If your hands hesitate, the form wobbles. If you rush, it caves in.
There’s a physical satisfaction in shaping something symmetrical. The wheel hums, your hands stay steady, and for a few minutes, your whole focus narrows down to the spinning surface in front of you. That’s the moment most people fall in love with pottery.
Drying
When you finish shaping your cup, it looks done but it’s not even close. Drying is the silent, invisible part of the From Clay to Cup process.
If the air in the studio is too dry, the edges of your cup will shrink faster than the base, creating hairline cracks. That’s why most pottery cafés, including ours, keep humidity around 60–65% and let pieces dry for 24 to 48 hours.
Temperature also matters. Warm air pulls moisture out unevenly, while cooler air lets water escape slowly through the clay’s natural pores.
| Condition | Ideal Range | Result |
|---|---|---|
| Humidity | 60–65% | Even drying, no cracks |
| Temperature | 20–24°C | Smooth surface |
| Drying Time | 36–48 hrs | Strong, stable form |
You can tell a piece is ready when it feels leather-hard cool to the touch but firm enough to handle. Tap it gently; if it gives a soft “tok” sound instead of a dull thud, it’s ready for the kiln.
The Journey of Transformation
Every step adds touch, patience, and chemistry to turn earth into art.
-
1. Clay Selection
Studio-grade clay (22–24% moisture) ensures flexibility without collapse or cracks.
-
2. Centering & Shaping
Wheel speed ~80 rpm; balance through gentle, even pressure — where rhythm becomes form.
-
3. Drying
Humidity 60–65%, Temp 20–24°C, 36–48 hrs — the slow path to stability and strength.
-
4. Bisque Firing
Heated to 950°C; water burns off, clay transforms to semi-porous ceramic — 9% shrinkage.
-
5. Glazing
Liquid silica & pigments form a glass layer; 0.4 mm coat for perfect transparency.
-
6. Glaze Firing
At 1230°C for 8–10 hrs; vitrification completes the journey — from clay to cup.
First Firing
The first firing, called bisque firing, is where the magic begins. The kiln slowly heats to about 950°C, removing all remaining moisture and transforming the clay into a semi-porous solid.
At this point in the From Clay to Cup process, the piece becomes permanent. If it cracks now, there’s no fixing it the clay’s chemistry has changed for good. But when the firing goes right, the result is a strong but porous material that’s ready for glaze.
Info.
During bisque firing, clay shrinks about 8–10%. That’s why the mug you shape on the wheel will always come out a little smaller than you expect.
After cooling, each piece gets lightly sanded to remove rough edges. It’s surprisingly satisfying to feel the smooth matte surface under your fingers halfway between raw earth and finished art.

Where Science Meets Art
This is everyone’s favorite step because it’s where color finally appears. Glazes are basically liquid glass a mix of silica, minerals, and pigments.
When applied to the bisque piece, they look dull and chalky, but once fired at 1200–1250°C, they melt and fuse into a smooth, glossy finish.
Different glaze thicknesses create different effects. A coat that’s 0.4 mm thick gives a light, translucent look. Anything thicker can cause drips or uneven surfaces. The firing atmosphere also matters: oxygen-rich firings bring out brighter colors, while reduction firings deepen blues and reds.
Many of our regulars love experimenting with layered glazes. Two thin coats of different hues can merge unpredictably, creating textures that look like watercolor or stone. That’s the charm you never get the same cup twice.
The Creative Chain
Every touch transforms both clay and maker — from physical rhythm to emotional meaning.
The Second Firing
The final kiln session — the glaze firing is the step that completes the journey From Clay to Cup.
Inside the kiln, temperatures climb gradually to 1230°C. Clay particles begin to fuse; the surface becomes watertight and resonant. When it cools, the mug makes a bright ring when tapped, a sure sign of proper vitrification.
This process takes about 8–10 hours of firing and another 12 for cooling. Energy costs vary, but on average, a single firing for a standard kiln batch costs around $25–30, depending on electricity rates and size.
When you finally open the kiln, that first look — the gleaming surfaces and unexpected shades makes every hour worth it.

Why Handmade Cups Cost More?
People sometimes wonder why a handmade cup costs $40 when a mass-produced one is $5.
But once you understand the full From Clay to Cup process, the reason becomes obvious.
Each piece takes hours of shaping, drying, glazing, and firing. Every firing cycle uses energy, every cup goes through inspection, and sometimes yes pieces break. The real price isn’t the materials (which might cost only a few dollars), but the time, care, and unpredictable nature of craft.
A good handmade cup lasts decades. It doesn’t just hold your drink it carries the memory of the person who shaped it. That human connection is what makes pottery more than just an object.
At LIMBACERAMICS, the process From Clay to Cup is both a craft and a community experience. We don’t rush the clay; we teach people to work with it. Whether you’re visiting for a casual session or designing your own set of mugs, every step is part of that mindful rhythm touch, shape, fire, and share.
Our café combines coffee aroma with the hum of spinning wheels. Some come to relax, some to create, and some just to watch the transformation happen in real time.
