Getting Started
You don’t need a ton of ceramics experience. You don’t need a kiln. You just need a flat surface, a little time, and the willingness to get your hands dirty and experiment. We'll walk you through everything from opening the bag to displaying your finished piece.
Setting Up Your Workspace
Before you open your clay, take a few minutes to get set up. A good workspace makes the whole process smoother and keeps cleanup minimal.
What You Need
• A flat, clean surface. A kitchen table or desk works perfectly. Avoid textured
surfaces like raw wood that can grab the clay.
• Something to protect your surface. Parchment paper, a
silicone mat, or even a large cutting board. The surface protection mat from
the nirii shop is designed for exactly this.
• A small bowl of water. You’ll use this to smooth cracks and soften the clay as you work. Keep a damp cloth or sponge nearby too.
• Your tools. Everything in your nirii kit, plus a few household items
if you want. A butter knife, a fork, a toothpick, and a rolling pin or smooth
bottle all work well.
Space and Lighting
Work somewhere with good natural light if you can. It’s easier to spot surface cracks and uneven thickness when the light hits from the side. Give yourself at least two feet of clear table space so you have room to work.
What to wear
Our clay washes out of most fabrics easily, but it’s still worth wearing something you’re not precious about. Roll up your sleeves. If you have long hair, tie it back.
Tools & Brushes
Your kit comes with an 8-piece sculpting tool set and a 3-piece brush set. Here's what each one does and when you'll reach for it.
Sculpting Tool Set (8 pieces)
Needle Tool: A thin steel point on a wooden handle. Use it to pierce holes, etch fine lines and details into the clay surface, and score surfaces before joining two pieces together. You'll use this on almost every project.
Ribbon Tool: Recognizable by its flat, looped metal end. Use it to scoop out clay and hollow forms, trim edges, and refine the shape of your piece. Essential for creating cavities in dishes and pots.
Loop Tool: Similar to the ribbon tool but with a rounded wire loop. Good for carving away larger amounts of clay, refining wall thickness, and cleaning up the insides of pots and vases.
Wood Modeling Tool: A double-ended wooden tool with two different shaped tips. Use the flat end to smooth and shape surfaces, and the pointed end to blend joins and add details. This is your go-to for general shaping work.
Potter's Rib: A smooth, flat piece (wood or metal) shaped to fit your palm. Press it against the clay surface to smooth and compress. Great for evening out walls, removing finger marks, and creating a clean finish.
Metal Scraper: A thin, flexible metal blade. Use it to smooth flat surfaces, trim excess clay, and create sharp, clean edges on slabs and trays.
Wire Cutter: A thin wire strung between two handles. Use it to slice through large blocks of clay or to cut a piece off your supply. Pull it taut and draw it steadily through the clay.
Sponge: Dampen it and use it throughout your entire process. Smooths surfaces, softens edges, blends small cracks, and keeps the clay workable. A little water goes a long way.
Brush Set (3 pieces)
Coverage Brush. The largest brush in your set. Use it to apply base coat, varnish, and broad washes of color over larger surfaces. Load it generously and work in smooth, even strokes to avoid visible brush marks.
Large Detail Brush. A mid-size brush for painting defined areas, filling in sections of color, and applying paint where the coverage brush is too big but you don't need pinpoint precision. Your workhorse for decorating.
Small Detail Brush. The finest brush in the set. Use it for thin lines, dots, lettering, and any precise decorative work. Best with a light hand and just a small amount of paint on the tip. This is the brush that makes your piece look intentional.
Working with Your Clay
Conditioning
When you first pull the clay from the bag, it might feel
a bit firm. That’s normal. Knead it in your hands for two to three minutes
until it’s soft and pliable, similar to the texture of Play-Doh. If it feels
dry or starts to crack while kneading, add a few drops of water and work it in.
How Much Clay to Use
Each project guide specifies roughly how much clay you’ll
need. As a general rule, start with a ball slightly larger than what you think
you need. It’s easier to remove excess than to attach new clay to a piece
you’ve already started shaping.
Keeping Unused Clay Fresh
Once the bag is open, the clay will start to dry out over
time. Wrap any unused clay tightly in plastic wrap or place it in a sealed
zip-lock bag. Push out as much air as you can. Stored this way, it’ll stay
workable for weeks. If it does dry out slightly, knead in a few drops of water
to bring it back.
Smoothing and Blending
Water is your best friend. Dip your fingers in water and
run them over the surface to smooth out cracks, fingerprints, or uneven spots.
For joining two pieces of clay together (like attaching a handle or a base),
score both surfaces with a fork or toothpick, add a tiny bit of water, then
press and smooth them together. This is called “scoring and slipping” and it’s
the most reliable way to get a strong bond.
Drying Your Piece
The Basics
nirii clay is air-dry, which means it cures at room
temperature with no kiln or oven needed. Most pieces will be fully dry and
solid in 24 to 48 hours, depending on thickness and humidity.
Best Practices for Even Drying
• Dry on a flat, breathable surface. A wire cooling rack
is ideal because it lets air circulate underneath. Parchment paper on a flat
surface also works.
• Flip your piece halfway through. After about 12 hours, gently
flip or rotate the piece so both sides dry evenly. This helps prevent warping.
• Avoid direct heat or sunlight. Don’t put your piece in the
oven, next to a heater, or in direct sun. Rapid drying causes cracking. Room
temperature, out of the way, is perfect.
• Be patient with thick pieces. Anything thicker than about one
inch may take closer to 48 hours or even a bit longer. You’ll know it’s ready
when the clay feels hard and is no longer cool to the touch.
How to Tell When It’s Done
Fully dried clay will feel hard, light, and uniform in color (wet spots appear darker). Tap it gently. If
it sounds solid rather than dull, it’s ready for finishing.
Sanding and Finishing
Sanding
Once your piece is fully dry, you can sand it for a
smoother finish. Start with medium-grit sandpaper (around 150) to shape and
remove rough spots, then move to fine-grit (220 or higher) for a polished feel.
Sand gently. Air-dry clay is sturdy but not indestructible, so let the
sandpaper do the work rather than pressing hard.
Painting
Acrylic paint works best on air-dry clay. Apply thin,
even coats and let each coat dry fully before adding the next. Two to three
coats usually gives solid, even coverage. If you want a more natural look, you
can leave the clay unpainted and just seal it.
Sealing
Sealing protects your piece and gives it a finished look.
Use a water-based polyurethane or acrylic sealer. Apply two to three thin coats
with a soft brush, letting each coat dry between applications. Sealing makes
your piece water-resistant, which means it can handle light splashes and wiping
down, but it is not waterproof or food safe. Don’t submerge sealed pieces in
water or use them to serve food.
Troubleshooting
My clay is cracking while I shape it.
The clay is too dry. Wet your hands and work a little
water into the surface. If it’s cracking at the edges while rolling, fold it
over and knead it again with damp hands until it’s more pliable.
My piece cracked while drying.
Usually means it dried too fast or unevenly. For small
cracks, mix a tiny bit of clay with water to make a paste, press it into the
crack, and smooth it over. Let it dry again. For next time, dry in a cooler
spot away from heat sources and flip the piece halfway through.
My piece warped while drying.
This happens when one side dries faster than the other. Flip your pieces at the 12-hour mark. For flat items like trays or dishes, you can place a flat, lightweight object (like a book wrapped in parchment paper) on top while it dries to keep it flat.
Two pieces I joined fell apart.
The bond wasn’t strong enough. Always score both surfaces and add water before joining. Press firmly and smooth the seam thoroughly. If a piece breaks after drying, you can re-attach with a strong craft glue.
My clay feels soft after 24 hours.
Thicker pieces take longer. Give it another 24 hours. If your environment is humid, it can take even longer. A dehumidifier in the room can speed things up slightly.
