Clay, Clay and More Clay!

Durable, Usable and Beautiful


We give little thought to the raw beauty of clay and how it has enriched our lives in so many ways. This organic form of earth has proven through the ages to be functional, medicinal and beautifying.


Functional Use


Man discovered clay when digging, and while rolling the mound of earth within his hands, he pondered and experimented in forming it. Making different objects, he learned that if shaped into vessels, he could store food and water in them. Clay had found its function.

Functional uses of clay can be seen in everyday use such as dishes, fruit bowls, flower vase, terracotta planter pots, bean pot and many other things. And let us not forget the toilet!


One slightly odd and unique functional use of clay is 3D printing with clay. A group called WASP invented a 3D printer that extrudes clay to build forms, functional pieces and can even create a shelter that also includes straw. The shelter resembles a beehive. This ingenuity lacks the human touch with clay but does provide compositions that are uniform and beautiful.

Medicinal Use


Most are not aware that clay has medicinal benefits and has been used to treat ailments throughout time.


  • Antibacterial
  • Gastrointestinal Problems
  • Detoxifies
  • Laxative
  • Diaper Rash

Beautifying Use


Clay has been known to be skin’s best friend. Spas worldwide offer treatments that have added benefits of using clay. It is considered a luxury to have a mud soak in a tub or have a clay massage.


Cosmetics and beauty products now come packed with the benefits of adding clay.


  • Foundation, concealer, and mineral face powder promote a healthier appearance and fight acne.
  • Facial masks containing clay exfoliates and purifies skin cells and has a rejuvenating effect.
  • Hair Products such as pomades, mousse, paste, and wax contain clay promoting healthier and shinier hair.

The Evolving Clump of Clay

No Red Carpet for the Brick

The simple little brick has never stood in the spotlight and severely lacks any palpable beauty or luster. It has changed the appearance of our world. What once was a barren horizon, now abounds with structures reaching for the clouds. All because of one little brick!

The Origin of Bricks


Around 7500 B.C. man took a clump of clay and formed it into a shape allowing it to dry and harden in the arid sun of Turkey. A brick was born!



Thousands of years ago, brickmaking was labor intensive and was produced by hand. The clay was kneaded by bare feet and pushed into wooden molding frames. Excess clay was wiped away, and the frame lifted exposing each individual brick. The brick was left exposed to the sun to dry.

Up until late 1800’s, bricks were made by hand yielding up to 36,000 bricks a week. However, once machinery took over and started mass production, the weekly yield was 80,000 bricks.


Because of the low cost and quick production of bricks, raw materials were no longer the preference for building structures. The anatomy of a brick structure was resilient, durable and cost less than those made with wood or other materials.


Did You Know???


  • Bricks are much more energy efficient because they hold the heat in during daylight hours and release that energy when it becomes dark.
  • Dark red or cranberry colored bricks have the deeper tint of red from being heated and fired at extremely high temperatures.
  • 70% of the world’s buildings are made of brick.
  • The Empire State Building has over 10 million bricks.
  • The Chrysler Building is the tallest brick building in the world.
  • A standard size brick weighs 5 pounds.
  • The BMM300 is part truck, part Zamboni and part locomotive which is filled with a mixture. As it drives, the mixture is extruded out onto the ground in perfect shapes of bricks. It can produce 300 bricks in 1 minute.
  • Some bricks have three holes in them to provide stability when used for walls, chimneys or foundations.

Getting Creative with Brick


Acme Brick in Ft. Worth, Texas set their creative gears in motion to set a precedence for their business. Gathering clay material from twenty three of their brick plants, the crew quickly put their thinking caps on trying to design the world’s largest brick.


After four failed attempts, moving forward a fifth attempt was made. Not only was it a success, but the birth of “Clay” set the world record as being the largest brick.


“Clay” weighed in at a whopping three tons and measured nine feet long.

The Beginnings of Pottery

Ceramics or Pottery?

Many confuse the term “ceramics” as relating solely to plaster, greenware or bisque.

However, “ceramics” is the umbrella term used for pieces produced from working with clay such as pottery.

What exactly is clay and where does it come from?

The earth provides this bountiful material and has continued to do so for centuries. Clay is formed when rocks containing feldspar are exposed to water. Depending on minerals that are in a body of clay, the colors can vary. For example: if a clay is red, it is because there is iron minerals present and if a clay is black, it is due to the presence of a mineral called manganese.

The First Works of Pottery

Mankind discovered clay around 24,000 B.C. It was thought that clay was found when digging. Man formed objects with the clay and put it in fire to harden it. This ingenuity led to the formation of vessels they made to hold water and store food. Clay bricks were also made which were used for building things.




When working with clay, maturity temperature, workability and color sets them apart from one another and defines what works best for a specific piece of pottery.


Maturity Temperature

  • Each type of clay matures at varying temperatures. Therefore it is fired to a particular temperature to reach the desired point of doneness.


  • A particular type of clay is chosen depending on its ease of forming without difficulty.


  • When making pottery, the type of clay may be chosen because of its color. When the clay has certain minerals (i.e., iron, manganese), it will have a distinct color.

Types of Clay


The type of clay is specifically chosen for a project because of its color and grain. There are three types of clay:



  • Color: Pure White
  • Grain: Fine
  • Uses: China Dishes, Figurines, Lab Equipment, Electrical Insulators


  • Color: Buff, Gray, Dark Brown
  • Grain: Coarse
  • Uses: Pots, dishes, sculptures, slab work


  • Color: Brown, Orange, Red
  • Grain: Fine
  • Uses: Flower Pots, Tiles, Sculptures


The Kiln


Once a piece of clay has been formed into the desired shape, it requires a drying method to become hard and sturdy. The formed clay is placed into a kiln to reach the desired hardness.


Primitive kilns date as far back as 10,000 years ago beginning with the pit kiln.


The pit kiln was a shallow hole dug in the ground where pottery was placed scattered in the pit, stacked, and fired. Once the pieces were cooled down, the ashes were cleaned off revealing a functional piece of pottery.

Types of Kilns Used Today


Throughout the ages, the kiln was perfected and modified to reach a desired effect on pottery pieces.


There are three types of kilns:



  • Most common type of kiln
  • Used for small loads


  • Runs on natural gas
  • Used for desired earthy coloring


  • Fueled by wood
  • Used for unique wood ash glazing


The Wheel


The pottery wheel or “potter’s lathe” is used for shaping the clay form with precision while using the hands, fingers or tools. By placing a lump of clay in the middle, the potter spins the wheel as they use their hands to smooth the clay as it turns.


Around 3,000 B.C., mankind began using a rough version of the wheel to perfect their form. Using a moveable platform to walk around, they manipulated and worked with their clay form.


Down through the centuries, the wheel was improved to meet the needs of the potter.

Today, most wheels are electric allowing the potter to control the speed; however, some prefer the rustic control of the wheel using their foot to spin the wheel.


Endless Beauty


Regardless of the period a piece of pottery came from, the organic and rawness are ever present in every piece.


Working with clay removes the potter’s thoughts from the clutter of life and places it on the simplicity of what earth has provided us to hold. The art of pottery not only produces beautiful and functional pieces, it provides a strong connection between the potter and the earth.
