How is China clay different from regular clay?
Ever played in the mud? Maybe you used clay to create a small animal or bowl in an art class. Clay is squishy and fun. It comes from the Earth. Did you know that there are different kinds of clay?
The majority of people believe that all clay is brown mud. This is not true. China clay is white. This is different than the red or brown stuff that you may find in your garden.
This post will answer the question What is the difference between regular clay and China clay? You will learn what the clays are made from, how they appear, and what people do with them.
Regular Clay vs. China Clay: Origins, Appearance, and Uses
What Is Regular Clay?
Let’s first talk about regular clay. Regular clay is the same clay that you find in backyards and riverbanks.
Where does it come from?
Clay is a mixture of small pieces of rock, which have been broken down and re-formed over a period of thousands of years. When wind and rain shatter rocks, they become dust. This dust is then mixed with other minerals and water to form clay.
What does it look like?
This clay type is typically brown, red or orange. Why? It contains a metal called iron. Imagine an old bicycle that turns orange and rusty. Iron does that! Regular clay is able to pick up impurities like iron rust and sand because it travels so much (by wind or by being washed in rivers).
How do we use it?
Bricks can be made from regular clay. The orange flower pots, called Terra Cotta, are also made from it. The material is strong, but not always very white or smooth.
What Is China Clay?
Let’s now look at our star: China clay. It has an interesting scientific name, Kaolin. The clay is named for a Chinese hill called “Kao-ling”, where it was first discovered.
Where does it come from?
China clay can be found in deep ground. It is usually formed right there. It doesn’t move down rivers, nor is it blown by the wind. It stays put. It stays clean and pure because it does not move.
What does it look like?
When asked, “How does China clay differ from regular clay?” China clay is white. The texture is very similar to flour. The iron in regular clay is not present. The clay is very smooth and fine.
How is China clay different from regular clay? (The Big Differences)
Let’s now compare the two. These are three of the main differences between them.
1. The Color Test
Color is the easiest way to distinguish them.
- Clay in dark colors such as red, brown or orange
- China Clay Bright white, pure and unadulterated.
When you heat up a regular oven to bake clay, it will usually stay reddish brown. China clay stays white and beautiful when it is baked.
2. The Heat Test
To make clays as hard as a rock, they must be baked.
- Regular clay: Melts when it becomes too hot. The clay is baked in lower temperatures.
- China Clay : Has the ability to handle extreme heat! The clay is extremely resistant to fire. It is also used in the production of porcelain cups and plates that are able to hold tea hot without breaking.
3. Stickiness Test
Clay is very sticky for potters (people that make pottery).
- Regular clay: Sticky and plastic like. The clay is easily shaped into balls.
- China Clay Does not stick very well. The clay can crumble and be difficult to work with on its own. It is often necessary to add a bit of clay to it in order to make it more workable.
Amazing Uses for China Clay
China clay can be used for more than just making bowls and cups. You can find it in a lot of things that you use at school every day!
It is in your paper
Feel a shiny white piece of printer paper. It feels smooth, right? China clay is usually to blame! The white clay is mixed into paper pulp by factories. Clay fills tiny holes and makes the paper bright, white and smooth.
It is in paint and rubber
China clay can be used to thicken and brighten white paint. Rubber, such as shoe soles or car tires, can also be strengthened by adding china clay.
Why is China clay called “Porcelain”?
People may mention “fine porcelain” or “porcelain dolls.” These are usually made of China clay.
China clay, because it is so pure and almost transparent, becomes glassy when it’s baked at high temperatures. You might see light shining through a thin teacup if you place it up against a bright light. Clay is usually too dark and thick to allow light through.
