A ceramic button gives a handmade garment a small point of weight and permanence. It can be plain and quiet, or carry a thumbprint, a stamped mark, a wash of colour, or the soft variation of a glaze. The work is simple in scale, but buttons ask for more care than many clay ornaments: they must pass through fabric, lie comfortably against the garment, survive handling, and account for the clay’s shrinkage in firing.
The most reliable approach is to make a sample first. Fire one or two buttons through the complete process, measure the finished result, test the holes with the thread and needle you intend to use, and wash the sample as you would the garment. Only then make the full set.
Choose clay and plan the finished size
For buttons intended for washable clothing, use a clay body that matures at its stated firing temperature. Stoneware and porcelain are generally suitable choices when properly fired in a kiln. Avoid treating air-dry clay as a substitute for fired ceramic on a garment that will be laundered; it does not offer the same long-term resistance to water and wear.
Clay shrinks as it dries and fires. The exact amount depends on the body, its firing temperature, and your kiln conditions. Rather than relying on a general percentage, make a test disk from the same clay, thickness, decoration, and firing schedule you plan to use. Measure it wet and again after the final firing. That difference tells you how much larger to cut the rest of the buttons.
A button also needs enough substance to be useful without becoming heavy. For many garment buttons, a slab around 3 mm thick is a sensible starting point, though a large coat button may need more strength and a small blouse button may be made finer. Keep the thickness consistent. Uneven clay dries unevenly and is more likely to warp.

Materials and tools
Gather the following before starting:
- Stoneware or porcelain clay suited to your available firing temperature
- Rolling guides and a rolling pin
- A button template, cutter, or a small knife
- A needle tool, skewer, or suitably sized hole punch
- A soft brush and a little clean water
- Fine sanding sponge for bone-dry finishing
- Underglaze, glaze, or slips compatible with the clay body
- A smooth board, plaster bat, or absorbent surface for drying
- Kiln access and a firing schedule appropriate to the clay and glaze
- A ruler or calipers, plus the needle and thread planned for sewing
A simple cardboard or plastic template is useful when you need a matched set. Mark it with the desired wet diameter after you have calculated shrinkage from a test piece.
Make a sample before making the set
A sample prevents the usual disappointments: holes that close, buttons that end up too small, a glaze that makes the edge sharp, or a shank that does not sit well against cloth.
Roll a small slab using guides. Cut one two-hole button, one four-hole button, and, if you are considering it, one shank button. Decorate and fire them exactly as you intend to fire the final set.
After firing, check four things:
- Finished diameter: Compare it with the buttonhole or planned buttonhole length.
- Hole clearance: Pass your chosen needle and thread through repeatedly. A hole may look open but still be awkward to sew.
- Edge comfort: Run a fingertip and a scrap of fabric over the rim and holes. Nothing should snag.
- Wear in use: Sew the sample to a scrap of the garment fabric. Fasten and unfasten it several times, then wash the sample in the manner appropriate for the finished garment.
Make adjustments in the clay stage, where they are easy: enlarge the holes, soften the edge, alter the thickness, or choose a different glaze treatment.
1. Roll an even slab
Wedge the clay briefly until it is uniform and free from obvious air pockets. Roll it between guides to an even thickness. Turn the slab once or twice as you roll rather than pressing repeatedly in one direction.
Let the slab rest for a few minutes if it has become very soft or stretched. Clay that is too wet tends to distort when cut and moved. It should feel pliable but hold a clean edge.
For a restrained surface, leave the slab smooth. For texture, impress it lightly with linen, lace, a carved stamp, or a small found texture. Keep impressions shallow around the holes and perimeter. Deep texture can make a button uncomfortable against fabric or difficult to clean.
2. Cut the button blanks
Cut circles, ovals, squares, or softly rounded rectangles. A round cutter produces the most consistent set, but a knife-cut shape can suit a visibly handmade garment. If cutting by hand, use a template and make calm, single cuts rather than sawing at the clay.
Lift each blank with a thin flexible rib, palette knife, or the support of your whole hand. Pinching a soft button at one edge can leave it oval.
Soften the perimeter immediately. Use a barely damp fingertip, small sponge, or soft brush to round both faces of the rim. The goal is not a swollen edge, but a gentle transition with no knife-sharp line.

3. Pierce holes generously
Pierce holes while the clay is soft enough to yield cleanly but firm enough not to close around the tool. Turn the button over after piercing and clean the small raised burr on the reverse side.
Make holes larger than seems necessary. They will shrink in drying and firing, and glaze can narrow them further. A needle tool makes small holes, but a skewer, narrow drinking straw, or purpose-made punch may be better for buttons sewn with thicker yarn or several strands of thread.
Two-hole buttons
Two-hole buttons are simple and often suit fine shirts, cardigans, and small garments. Place the holes evenly across the centre line, leaving enough clay between them and around the outside edge. Keep the holes away from a fragile narrow waist in an oval or shaped button.
Four-hole buttons
Four-hole buttons distribute the strain of sewing and are useful on larger buttons or garments that receive frequent handling. Arrange them in a neat square or rectangle. Check that the spacing allows a needle to travel without scraping the neighbouring hole.
Shank buttons
A shank button has a loop on the reverse instead of holes through the face. It can be useful where a raised button suits the garment, but it needs careful construction. Form a sturdy loop from clay, score and join it securely to the back with slip, then smooth the join without filling the opening. Keep the shank opening broad enough for thread and allow room between loop and button back for fabric.
Shanks are more vulnerable than pierced holes because they project from the button. Make a test and avoid a long, thin loop. A short, substantial shank with a well-compressed join is safer in firing and wear.
4. Dry slowly and keep buttons flat
Small pieces dry quickly, which can be convenient but also invites warping. Place the buttons on a smooth absorbent surface and cover them loosely with plastic or paper for the first stage of drying. Turn them once they are firm enough to handle without bending.
If a button begins to cup, gently reverse it onto a flat surface while it is still leather-hard. Do not force dry clay flat. It may crack or retain internal stress.
At the leather-hard stage, inspect each hole and edge again. Refine roughness with a damp sponge used sparingly. Once bone dry, use a fine sanding sponge to remove any remaining sharp clay burrs, particularly inside the holes and along the rim. Wear a suitable dust mask and avoid creating dust indoors; dry clay dust should not be breathed in.
5. Decorate with use in mind
Underglaze, slip, and glaze can all work, provided they are compatible with the clay body and firing temperature. A plain unglazed button can be pleasing, especially in a smooth stoneware or porcelain, but it should be fully fired and carefully sanded where needed.
For glazed buttons, keep glaze away from the hole interiors and from the surface that will sit against fabric unless your firing method and glaze are known to behave well there. Glaze can pool in holes, fuse a button to the kiln shelf, or leave an unpleasantly sharp edge. Wax resist can help protect the back and holes, though careful brushing is often enough for a small batch.
Apply glaze thinly and evenly. A heavy application may obscure texture, close narrow holes, or run. If you want a glossy face with a clean sewing surface, glaze only the front and leave the back unglazed and smooth.

6. Bisque fire, glaze fire, and inspect
Fire according to the clay and glaze manufacturer’s stated range and the practices of the kiln you are using. Buttons must be fully dry before bisque firing. Damp clay can fail in the kiln, and thin pieces are not exempt from this basic requirement.
For the glaze firing, place buttons on a clean, level kiln shelf only where no glaze can touch the shelf. If a button is glazed on both faces, it requires an appropriate firing support, but supports can leave marks and may be unsuitable for a small shank or delicate form. In many cases, glazing only the face is the simplest and most dependable choice.
After cooling, inspect every button individually. Check for cracks around the holes, sharp glaze points, warping, and roughness on the back. Test the thread path once more before sewing the buttons to a finished garment.
Sewing ceramic buttons onto a garment
Ceramic is harder and less forgiving than horn, wood, or shell, so use a thread strong enough for the garment and sew with a small thread shank beneath a flat button. This little space allows the fabric layers to sit under the button without straining the thread.
For a two- or four-hole button, stitch firmly but do not pull so hard that the button is clamped against the cloth. For a ceramic shank button, use a small reinforcing button or disk on the inside of a heavy garment if the fabric needs support. Check the first few wearings and tighten any thread that begins to loosen.
Mistakes worth avoiding
- Cutting to the final desired diameter in wet clay: Fired buttons will usually be smaller. Work from a fired test.
- Making holes only needle-width: Shrinkage and glaze can turn them into frustratingly narrow passages.
- Leaving crisp cut edges: They catch thread and feel abrasive against cloth.
- Drying on one side too quickly: This is a common cause of cupping and warping.
- Glazing the entire button without a firing plan: Glaze on the underside can adhere to the kiln shelf.
- Using a thin, poorly joined shank: It may crack at the join in firing or snap in use.
- Skipping the garment test: A sound-looking button can still be too heavy, too rough, or too awkward for its intended fabric.
A matched set need not be mechanically identical. Slight variations in tone, rim, and surface are part of the material’s character. What matters is that the buttons are consistently functional: smooth to touch, generously pierced, properly fired, and quietly suited to the cloth they will fasten.
