We spend most of our days talking about clay, glazes and kilns, but we also love the history behind all of it. People have been making ceramics for thousands of years, and knowing a little about how we got here makes the materials and techniques we use today a lot more interesting.
When you center clay on the wheel or open a glaze kiln, you're doing something people have done for a very long time. The basic process of shaping clay, drying it and firing it hasn't really changed in 25,000 years. What has changed is how much we understand about it, the tools we have, and the huge range of ways potters work.
Where ceramics began
The story starts more than 25,000 years ago, when early people noticed something useful. Mud that dried in the sun got hard, but mud that was shaped and then put in a fire got stone hard and held water.
The first clay objects
The earliest ceramic objects weren't pots at all. They were figurines. The Venus of Dolní Věstonice, made around 29,000 to 25,000 BCE in what's now the Czech Republic, is one of the oldest ceramic objects we know of. Pieces like this weren't fired in kilns. They went into open fires or pits that barely got hot enough to harden the clay.
Pots for everyday use came much later, around 18,000 to 20,000 years ago in East Asia. Some of the earliest have been found in China and Japan. They changed daily life. People could store grain through the winter, carry water over long distances and cook foods they couldn't eat before.
Why clay was such a big deal
Early potters figured out that clay from riverbanks and lakeshores was plastic when wet, held its shape when dry and became permanently hard when fired. Almost no other natural material does all three. Stone is hard to shape. Wood burns. Clay changes into something new.
That change from soft mud to hard ceramic is still the part that gets most of us hooked.
Ancient pottery traditions
Pottery developed independently in different parts of the world, and each tradition added something that potters still use.
Egypt
Egyptians were making pottery by 5000 BCE, with well-developed ways of forming, decorating and firing it. They found that certain mineral additives made bright glazes. The well-known Egyptian blue-greens came from copper compounds.
Egyptian pottery had both everyday and religious uses. Storage jars held grain, oil and wine. Canopic jars held organs for the afterlife. Decorated vessels showed gods, pharaohs and scenes from daily life, and many of them still survive.
What they gave us: alkaline glazes, and the idea of pottery as both everyday ware and ceremonial object.
Greece
Greek potters (roughly 1000 to 300 BCE) turned pots into a place to tell stories. With the black-figure and red-figure techniques, painters showed myths, athletes, battles and ordinary life in remarkable detail.
They also settled on forms made for specific jobs: amphorae for shipping wine and oil, kraters for mixing wine with water, and the kylix for drinking. Each shape was refined over generations until it worked well and looked good.
What they gave us: the idea that a useful pot can also be a serious piece of art.
China
China is responsible for what may be the biggest technical leap in pottery history. Around 600 CE, Chinese potters developed true porcelain, a clay body fired so hot (1300°C and up) that it fully vitrifies. It comes out translucent, rings when you tap it, and is very strong.
The secret was closely guarded for centuries. European potters spent hundreds of years trying to copy it and finally managed it in Germany in the early 1700s. Chinese potters also pioneered celadon glazes, underglazes and overglazes, along with a huge range of decorating techniques.
What they gave us: high-fire porcelain, and the idea of ceramics as luxury objects worth as much as gold.
Other traditions
Japanese pottery brought its own way of seeing things: wabi-sabi (beauty in imperfection), raku firing for tea ceremony bowls, and a taste for natural, unforced forms. All of that still shapes a lot of studio pottery today.
Middle Eastern and Islamic ceramics pioneered luster glazes, detailed geometric patterns and calligraphy as decoration.
Native American pottery developed skilled hand-building, burnishing and pit firing, which give beautiful surfaces with no glaze at all.
Each of these traditions passed down ideas about clay along with the techniques.
The Industrial Revolution
From the late 1700s through the 1800s, industry turned ceramics from handmade goods into something almost anyone could afford. The point wasn't so much better pottery as more of it, for more people.
What changed
- Motor-driven wheels replaced kick and hand wheels, so potters could work longer and more consistently. Jigger and jolly machines turned out identical plates by the hundreds.
- Coal kilns, and later gas kilns, reached higher and steadier temperatures than wood. That made it possible to produce specific clay bodies and glazes reliably.
- Commercial clay processing meant potters no longer had to dig and refine their own clay. They could order clay that behaved the same way from batch to batch.
- A scientific understanding of glaze chemistry led to stable, repeatable recipes instead of trial and error.
The trade-off
Factory production made dishes and tiles affordable for ordinary families. The cost was that a lot of industrial ware lost the individual character that makes handmade pottery special.
That's where today's split comes from: mass-produced ceramics for everyday use, and studio pottery for people who want something handmade. Both have their place, and studio potters owe a lot to industry. Standardized clay bodies, reliable glazes and accurate electric kilns all came out of industrial research.
Pottery today
Modern ceramics borrows from everywhere. A potter in California might use Japanese raku firing and Italian majolica decoration on a form based on an ancient Greek pot.
Old techniques, still in use
Raku comes from Japan. Pieces come out of the kiln red hot and go into combustible material, which gives dramatic surfaces and metallic lusters. Potters all over the world fire raku now.
Majolica (maiolica) comes from Italy and the Mediterranean. You paint oxide colors onto an unfired white glaze, which gives bright, painterly surfaces. Plenty of potters today use it on forms a Renaissance Italian potter wouldn't recognize.
Soda firing has European roots. Sodium goes into a hot kiln and forms a glaze on bare clay. Modern potters have refined it to get surfaces you can't get from a glaze bucket.
Crystalline glazes were developed in the late 1800s. They need precise temperature holds to grow crystals, and modern kiln controllers make that far easier than it used to be.
Where potters are taking it now
- Mixing clay with metal, wood, fiber and glass
- 3D printing forms you couldn't throw or hand-build
- Greener studios, with solar kilns, local materials and less waste
- Ceramics as architecture, installations and large sculpture
- Stretching what counts as functional pottery
Even the most experimental work rests on what came before. Knowing the traditional techniques is what lets you break the rules on purpose.
How history helps in your own studio
This isn't just trivia. Knowing some history can make you a better potter.
Troubleshooting
If your glaze crawls, it helps to know potters have been fighting that problem for thousands of years and have worked out fixes. Old recipes and methods still solve modern problems.
If your pots crack while drying, the answers ancient potters found still apply: dry slowly, keep the walls even and wedge well.
Ideas to build on
You don't have to invent everything yourself. Japanese tea bowl shapes, Greek amphora proportions and translucent Chinese porcelain all took centuries to refine. Study them, borrow from them and make them your own.
Being part of something bigger
When you throw a pot, you're joining a line of potters going back 25,000 years: Egyptians working Nile clay, Greek painters putting myths on vases, Chinese potters making porcelain thinner than seemed possible, and countless potters whose names nobody remembers, whose work kept their communities fed and supplied.
We think that's worth remembering. Pottery has always been about more than the objects themselves.
What modern potters have going for them
In a lot of ways this is a great time to be a potter. Compared with potters in the past, you have:
- Materials from anywhere. Clay from Kentucky, glazes formulated in Ohio and tools from Japan are all a few clicks away. Ancient potters had to use what was nearby.
- Reliable equipment. Electric kilns fire to exact temperatures and gas kilns have precise controls. Ancient potters lost whole kiln loads to unpredictable fires.
- Knowledge from all over. Online videos, workshops with teachers from other countries and potters to talk to worldwide. Traditional potters learned what their own village knew.
- Safer materials. Modern glazes and clays are made without lead and the other hazardous materials that were common in historical ceramics.
Some things haven't changed at all. We still center clay by hand and feel it respond. We still open the kiln hoping the glazes came out. And we still make things that are meant to be held and used.
Your part in the story
Every pot you make, from a first wobbly mug to a big sculptural piece, adds to a story that's been going for thousands of years.
At Sheffield Pottery, we're glad to be part of it. Our pottery wheels, kilns, clay bodies and glazes are modern tools built on very old foundations, and we're always happy to help you find the right ones, if you're brand new or have been throwing for decades.
