Intro To Clay

- 2. Please do not throw, misuse or waste clay – it is very expensive! DO NOT DUMP SLIP DOWN THE DRAINS!!!!!!!. Scrape excess slip into the slip bucket Please scrape clay from tools, wooden trays and tables into garbage can at the end of every class Keep your clay wrapped in plastic every time you’re not using it. Don’t leave it unwrapped for more than 15 minutes or it will crack and split ABSOLUTELY NO FOOD OR DRINK IN CLASSROOM. This is more for your health than anything else
- 3. Tools you may need to work with clay: • A fettling knife • A fork • A water container with a little water in it • A rolling pin (not a mallet) • A board to work on • A needle tool or white plastic tool with a sharp end • Ribbon tools

- 7. Preparing the clay for use by kneading. This removes air bubbles, and aligns the clay particles, which increases plasticity. Plasticity is the property of clay that allows it to be worked and reshaped. Old clay that is unfired can be re‐wedged and re‐used over and over.
- 8. Hand building technique: Joining flat sheets of clay together to create a something out of clay
- 9. Slabs can be wrapped and draped to create round and curved objects as well as straight sides

- 11. What part(s) of a goblet might we use the slab technique to create (cup, stem or base?) How would we do this?
- 12. Cut a rectangle out of a piece of scrap paper using a ruler. Make the horizontal measurement of it the size of your goblet stem’s height. Roll out a slab by semi‐flattening a piece of clay onto the board. Set up the slab sticks on either side and use your rolling pin to roll out a slab. The sticks allow for a consistent thickness throughout. Flip your slab every few rolls of the pin to keep it from sticking to the board
- 13. Make sure your slab will fit the size of your rectangle template. Put the template on the slab and use the fettling knife to cut the rectangle. Save any good size slabs you have left for practice later. Re‐wedge small scraps and place at the edge of your board for reinforcing seams later on.

- 16. A very wet form of clay, used as an adhesive between two pieces of clay to join them to one another. Make slip by adding tiny bits of unfired clay into a little bit of warm water. Stir together until it has the consistency of thick tomato soup. You may also use scrap clay in water left overnight to create slip.

- 18. Score the two edges of your rectangle you plan to slip together to create the stem Score deeply enough to give a real tooth the clay so that the two edges can bond together Add a good amount of slip and carefully align the two edges to form a cylinder for your stem Once created, set aside to let the air cure the clay and bit to make it less fragile to work with
- 19. Handbuilding Technique Typically used to make bowls, cups and other vessels At first try, coil built vessels are crude but after some practice they can be very well crafted and sophisticated Among the oldest techniques for building with clay
- 20.
- 21. Cut several even sized pieces of clay onto your board . Use a light, quick, back and forth motion for rolling with only your palms, not your fingers. Every so often dip your fingers in water to moisten the snake. Otherwise the snake will crack and break. Start at the center of your clay and work outwards
- 22. Repeat several times to create a stockpile of about 5 snakes each about a ¼” in diameter. Cut the snakes with a bevel edge (angled edge) to ensure they will stick together
- 23. Begin by wrapping a snake into a spiral. Score and slip along the top of the spiral you’ve created and at the end of snake where it’s cut at an angle. Continue to stack, score and slip coils to create a bowl shape. Smooth the coils together with your fingers to begin to make them disappear.

- 26. What part of your goblet could we create through pinching?
- 27. Begin to build and assemble the different pieces of your goblet. If you don’t like what you have, re‐ wedge and re‐work it Everyone will encounter different challenges so please be patient and try/experiment to solve your problem if I can’t be with you Don’t worry about surface design of your piece yet. We’ll look at that in a few.
- 28. Use these techniques once you’ve built the basic solid form of your goblet These are the ‘jewelry’ of clay handbuilding. It’s the place you can really let your creativity go and perfect your clay piece These surface design techniques take a good deal of patience and practice to master
- 29. Many different tools to incise or carve into clay A ribbon tool is used to gouge out areas of clay. Different size ribbon tools create different size carvings
- 30.
- 31. Use a needle tool or other sharp implement to carve designs out of your clay piece
- 32. This takes patience to do cleanly. Oftentimes you’ll have many clay ‘boogers’ that will remain on your clay piece. Slightly wetting the area you’re carving with a damp sponge will help remove these boogers Practice this on a scrap slab using different tools.
- 33.
- 34. When creating hollow forms it’s highly recommend to pierce holes in the clay to allow air to flow through when being fired in the kiln. Oftentimes piercing is more successfully accomplished when the clay is a slightly harder otherwise the pressure of piercing can skew your form Practice piercing a scrap slab as a part of a design AND as a functional air hole
- 35. Slipping and scoring additional shapes and forms onto a clay vessel Draw and cut templates from scrap paper prior to cutting your shapes from clay Use the same techniques we used for cutting the rectangular slab pattern. Bevel if you wish but it’s not necessary here as we aren’t seaming anything together
- 36. Draw and cut a few random shapes from scrap paper Put the template onto a scrap slab and cut around with a fettling knife Slip and score the back of your applique piece and the spot you want to apply it to on your scrap slab. Reinforce the edge with a thin coil you smooth from sight.
- 37. Press different textures or objects into clay to make marks There are an infinite amount of things out there to impress into clay so be creative
- 38. You can even create your own. One idea: using hot glue on a solid surface to create a design. Impress the dried glue into clay and see what happens. What can you think of to impress into clay?
