How to Make a Clay Pot

Tuesday, May 3, 2016 Add Comment Edit

The venerable clay pot has its roots deep in ancient history. Our ancestors needed vessels to carry water and store food, and found the water-resistant naturally occurring clays in the soil were ideal. Even though today we can buy our vessels at the store and usually carry our water through pipes, clay pots remain beautiful, and are functional works of art and craft.

EditSteps

EditPreparations

  1. Wear clothes that you don't mind getting grubby and dirty. You are essentially working with refined dirt, so it's going to be a messy business.

  2. Knead the clay. Start with about 1/2 pound (.25 kilos) of clay. Slowly warm it and work out the air bubbles by kneading it with your hands. This will even out the clay’s consistency, eliminating lumps of soft spots, and make it more pliable and easier to work with. Take care to avoid folding, poking, or other actions that could add air pockets and bubbles to your clay—these could cause your pottery to explode in the oven.

  3. Slice your clay in half with a stiff wire, and check for bubbles or gaps.

  4. Once your clay is kneaded, try one of the methods below to make your own pot.

EditCoiled Clay Pots

  1. Once the clay is warm and pliable, take a fist-sized clump and roll it into a long rope called a coil. The diameter of the coil will determine the thickness of your pot's walls. For your first pots, roll your coils out till they’re a little thicker than a pencil, and about 12 to 24 inches (30 to 60 cm) long, and of uniform thickness.

    • You may get thin or weak spots as you roll your coil out. Try avoiding that section as you work, but if it becomes a problem just break the coil at the weak spot, set one part aside, and finish the other.
  2. Create the bottom. Starting from one end, wrap the coil in a spiral until the bottom is the size you have in mind. For example, for a pot using coils about 1/4 inch (.6 cm), your base might be 3 inches (8 cm) in diameter.

    • You can also create the bottom by rolling out some clay to about the same thickness as your coils, and then trim the excess with a knife, using cup or plate as your guide.
  3. Prep the clay and start working. Score the outer 1/4 (.6 cm) inch of the bottom, and dampen with water or slurry (a thin mix of clay and water). Do the same with the bottom of the coils as you work. This will improve the clay bond and make your pot stronger. Lay the first coil on top of the base, and wrap it around, building up the wall.

  4. Strengthen your pot. To make your work durable, strengthen the clay bond by smoothing down the inside of the pot, forcing down the clay from the upper coil into the joint below it.

    • To maintain the shape of your pot, support the outside of the pot as you smooth the inside.
    • You can smooth both inside and outside if you wish.
  5. Shape your pot as you make it. Create your contours by adjusting the placement of the coils, and shaping the clay during the smoothing and strengthening process.

  6. Finish your pot. Add any decoration or glazing as desired, and depending on what kind of clay you are using you may air-dry your pot, bake it, or fire it in a kiln. Follow the manufacturer’s instructions on the correct method.

EditMake a Pinch Pot

  1. Make a ball. Roll the clay into a ball, and make sure it's moist.

  2. Make a hole. Punch your thumb into the middle of the clay ball, to about 1/4 inch (.6cm) from the bottom.

  3. Work the sides. With your thumb and forefinger, pinch the clay and press upwards. Work all around the inside, and with each pass, pinch from the bottom and move up, repeating until your vessel has the shape you want.

  4. Flatten the bottom. Press from the inside, against the table you're working on, so that the bottom is smooth and flat.

  5. Smooth out the inside and outside of the pot, as desired. Decorate, and follow the manufacturer's instructions for curing and finishing your pot.

EditUsing a Wheel

  1. Smack your clay. Throw it firmly from hand to hand, smacking it into a ball shape.

  2. Dry your wheel. This will help the ball of clay adhere to the wheel once it starts spinning. The last thing you want is a ball of wet clay flying across the room.

  3. Have some water. Place a bucket of water where you can easily reach it to wet your hands while you work.

  4. Throw the clay. Throw down the ball of clay as close to the center of the wheel as you can, then press it down into a conical shape.

  5. Start spinning. As you build up speed, wet the clay, and with one hand on the side of the clay lump, and the other side on top of it, ease the clump towards the middle. Use the upper hand to keep the clay from flying out of control.

    • You can tell the clay is centered when it no longer looks like it's wobbling, but sitting stationary in the center of the spinning wheel. Don't stop spinning.
  6. Wet your hands. Then work the clay into a cone, then press it down into a thick disk. Repeat this step a couple times. This is known as "wheel wedging" and helps to condition the clay. Make sure you keep the clay centered as you work.

  7. Push a thumb into the middle of the spinning mass, until it's about 1/2 inch (1.5cm) from the bottom.

  8. Push 4 fingers into the hole, and work them around until the hole is as big as you would like. Continue working the hole, using a hand on the outside of the clay to shape your pot.

  9. Work slowly. Gradually pull the clay up with even pressure, until it's the desired height.

  10. Spread the top. If you want it a bit wider at the neck, just pull back with your inside fingers. Don't do it too hard.

  11. Remove the finished pot from the wheel. Wet the wheel (not the pot) and using a stiff wire or fishing line, and holding it with both hands, pull it from the back of the pot towards you until the pot is separate from the wheel.

  12. Follow the manufacturer's instructions for finishing and firing your clay pot.

EditTips

  • If your pot collapses during the coiling process, just knead out the air bubbles and start a new pot.
  • Don’t use your fingertips when kneading the clay
  • A great trick to eliminate air pockets is to keep the clay in a round shape, never flattening the clay more than halfway. and keep throwing the clay back and forth between your hands. You can also throw the clay on a hard surface (like a table) multiple times.
  • You can also make a coil pot by using a mold. Just lay the base in a plant pot and the feed the coils into the pot and join together before tipping the pot out by loosening the top by pushing away from the sides with your finger. You can then join the outside and shape with a paddle or by rolling the pot on a table. If you want a closed pot then do this process twice and stick the two halves of the pot together with slip.
  • If you have purchased an oven-fired clay, you'll want to bake it on a glass surface. This is to ensure that the clay will release. An upside-down dish works well.

EditWarnings

  • Carefully follow the instructions on how to bake your clay if it is not an air drying kind. This is because if dry clay gets into the air or flicked about, it forms a dust called silica dust which causes long term health problems.
  • Follow the directions for materials to work on. Some clays will stain wood.
