What are the basic hand building techniques for clay
The three basic techniques of hand building are pinch, coil and slab construction. They can be used individually or combined together to suit your whims. Making a pinch pot is the simplest way to begin working with clay. You start by kneading the clay into a small lump about the size of your fist.
What is the slab technique
The slab building technique involves rolling out clay to an even thickness – usually 1 cm – then cutting shapes, folding, bending, manipulating and joining together to form a finished object. Slab objects are left to dry EVENLY before bisque firing for at least 7 days – turning regularly.
What are the 5 steps in pottery construction
Terms in this set (5)
- make pot. when joining pieces of clay, scratch to attach, slip to be hip, smooth to groove.
- dry pot completely. this is called greenware.
- bisque fire the pot. this is called bisque ware.
- glaze. glaze your bisque ware and clean the bottom or it will stick to kiln shelf.
- glaze fire.
What is the slab method of working with clay
Slabs can be made in a variety of methods. The most common method is to roll out the slab by hand using a rolling pin. Other methods include using slab rollers, extruders, and hand tossing. Slab rollers are large pieces of equipment that enable potters to roll large slabs to uniform thicknesses rapidly.
How do you join two pieces of clay together
Mark where the pieces are to be joined to each other. Using a serrated scraper (my favorite), fork, pin tool, knife, or other sharp tool, score grooves into the clay. Cross-hatch the grooves and make them deeper than just very light surface scratches.
What are the clay stages
– Stages of Clay
- Slip – Potters glue.
- Plastic or wet – The best time for pinch construction, stamping and modeling.
- Leather hard – The best time to do slab construction or carve.
- Bone dry – The clay is no longer cool to the touch and is ready to be fired.
- Bisque – Finished ceramics that has been fired once.
What is the pinch technique
A pinch pot is a simple form of hand-made pottery produced from ancient times to the present. Simple clay vessels such as bowls and cups of various sizes can be formed and shaped by hand using a methodical pinching process in which the clay walls are thinned by pinching them with thumb and forefinger.
How thick should clay slab be
A wide rolling pin will help to ensure that you create a slab with a consistent thickness. You want your slab to be no less than a 1⁄4 inch (6.4 mm) thick so that it is sturdy enough to use without breaking. If your rolling pin is too thin, you may end up with ridges in the middle of the clay.

How do you make a slip
The process of slaking clay to make it into slip is a simple one. Step one is to have a 5-gallon bucket filled 60-75% with your bone-dry clay then add water until it’s a few inches below the rim (figure 1). Let it slake for 24 hours then mix it by hand a little with a stick (figure 2).
How do you make earthenware clay
Grind your dry clay into powder and add a little water to rehydrate it. Before making your pot, you’ll want to add some sand or stone dust to “temper” the clay. Add one part sand or crushed quartz to two parts clay (temper should be 1/3 the volume). Once blended, the temper and clay mix is ready to form pottery.
How do you make homemade pottery clay
- Stir salt and water in a saucepan over heat 4-5 minutes.
- Remove from heat; add cornstarch and cold water.
- Stir until smooth; return to heat and cook until thick.
- Allow the clay to cool, then shape as desired.
- When dry, decorate with paint, markers, glitter, and so on.

How do you work with clay
Working With Clay:
PINCH – Use your fingers to pinch and poke a single lump of clay into any shape. SLAB – Roll the clay into flat sheets (like a pie crust) to cut apart and assemble. COIL – Roll out long snakes of clay and twist them into coils and shapes. WHEEL – Spin clay on a potter’s wheel to form pots and vases.
How do you shape clay
For instance, to shape a simple bowl using the pinch method:
- Take a lump of your clay and roll into a ball.
- Set the ball down on your work surface, pushing it down slightly to hold it in place.
- Make a small impression in the center of your ball.
- Pull the clay horizontally away from the center hole to widen the bowl.
