Some pots carry more than others. Here is how to make one.
An urn is the most meaningful commission a potter ever takes: a vessel for a person, a pet, or a keepsake portion of either, made by hands that cared. It is also, technically, a lidded jar with three extra responsibilities: it must hold a specific volume, its lid must seat with dignity and seal for good, and it must be built to last generations. This page teaches the whole craft two ways, thrown on the wheel or built entirely by hand, with a path toggle below so you only read the method you will actually use. Everything else, the capacity math, the lid and seal design, the personalization, is shared, because it matters the same no matter how the walls go up.
A vessel for a person, a pet, or a keepsake portion of either, made by hands that cared. Below: the capacity math that cannot be wrong, the lid and seal, the seven-decision plan, and one complete build on video. The full craft, on the wheel or by hand, is one toggle away.
The urn, condensed to its duties
- The capacity cannot be wrong. One cubic inch of interior volume per pound of body weight; a standard adult urn is about 200 cubic inches, just under a gallon. Build the wet pot generous, then verify the finished, fired vessel with measured water or rice, because the fired measurement is the only one that counts. Bound for a columbarium niche? Get its dimensions in writing first.
- The lid seats deep and seals for good. A proper interior gallery or flanged cap, never a shallow decorative fit. No threads in clay: the seal is silicone or epoxy run around the flange at filling, or removable museum putty for a shelf urn, so keep the mating surfaces clean and smooth.
- Two honest paths. On the wheel it is a tall lidded jar thrown with patience: calipers at the gallery, lid from the same clay on the same day. By hand it is a slab base, truly blended coils, and a slab lid flanged with a coil. The toggle above holds the full walkthrough for whichever is yours.
- Built for generations. Slow drying, both firings, and a stoneware taken to maturity at cone 5½: dense enough for a shelf, a niche, or the ground.
- Permission and calendar. You are allowed to make one before anyone needs it, and the kindest urns are made that way, because the honest build takes weeks.
Then settle the seven decisions below before the first wedge. The full craft, capacity to inscription, is one toggle away in the Comprehensive Version.
Permission to make this pot
Two honest things before any clay moves. First: you are allowed to make an urn before anyone needs one. Potters practice this form on ordinary days so their hands are ready on the day it matters, and an urn that never gets used spends its life as a beautiful lidded jar, which is no failure at all. Making one for a still-thriving fourteen-year-old dog is not morbid; it is love doing prep work.
Second: give this build more calendar than usual. Between making, slow drying, two firings, and the care you will want to take at every step, a finished urn is a matter of weeks, not days. Families in the middle of loss often need a vessel faster than clay allows, which is exactly why the kindest urns are usually made ahead, with time to spare and steady hands. This page assumes you are giving the pot the schedule it deserves.
The capacity math
Everything else on this page is craft; this band is duty. An urn that comes up short is a heartbreak no glaze can fix, so the volume gets calculated first and verified last.
- The standard rule: one cubic inch per pound. The funeral industry’s long-standing guideline is roughly one cubic inch of interior capacity per pound of body weight before cremation. A standard adult urn is built to about 200 cubic inches, and the same one-to-one rule sizes a pet urn from the pet’s weight.
- A gallon is your gut check. One US gallon is 231 cubic inches, so a standard adult urn holds just under a gallon. If you can picture a gallon of milk fitting inside with a little room to spare, your interior is in the right neighborhood.
- Build generous, then verify. Clay shrinks roughly 10 to 13 percent in every direction on its way to fired, which compounds into a much bigger loss of volume than intuition expects. Aim your wet interior comfortably past the target, then verify the finished, fired vessel the honest way: fill it with measured water or dry rice and do the arithmetic. The fired measurement is the only one that counts.
- Measure the destination too. If the urn is bound for a columbarium niche, get the niche’s interior dimensions in writing before you build; many niches are compact, and a magnificent urn that does not fit its home is the second heartbreak this band exists to prevent. Burial vaults and home shelves are roomier, but ask anyway.
- Keepsake urns are exempt from all of it. Small companion vessels holding a token portion can be any size the heart wants, which makes them a gentle first urn project.
The lid and the seal
An urn lid has two jobs an ordinary jar lid does not: it must seat with quiet dignity in a hard moment, and it must be sealable for good. Both are design decisions you make before any clay moves.
- Choose a deep-seated style. A lid dropped into a proper interior gallery, or a cap style with a generous inner flange, seats positively and cannot skate. Shallow, decorative fits that shrug off with a bump have no place here. The measuring discipline, calipers at the wheel, lid and body from the same clay on the same day, a little clearance built in for glaze, is the same one from our lids that fit page .
- Forget threads; plan the seal. Clay does not do screw threads worth trusting, and it does not need to. The universal practice is a mechanical fit finished with an adhesive seal at the time of filling: clear silicone or two-part epoxy run around the flange seats the lid permanently, invisibly, and reversibly-with-effort. For an urn that will stay on a shelf and may be opened, a bead of removable museum putty holds the lid honest instead. Design the flange so either seal has a clean surface to grip, which mostly means leaving the mating surfaces unglazed or lightly glazed and smooth.
- Give the knob some gravity. A hollow, generous knob or a low domed cap reads calm and handles surely. This is one pot where a whimsical knob usually strikes the wrong note, though for a pet urn, a small sculpted ear or paw can be exactly the right one.
- Vent nothing, trap nothing. Unlike a casserole, an urn wants no steam hole and no rattling parts: one body, one lid, one clean interior with no interior ledges to catch. Simple inside, expressive outside.
Throwing the urn
On the wheel, an urn is a tall, generous lidded jar thrown with unusual patience. The sequence:
- Weigh for the volume, not the vibe. Work backward from your interior target: a standard adult urn wants a serious lump of clay, and centering it is the day’s first real work. If that much clay is past your comfort, throw the body in two joined pieces; the whole craft of stacking thrown sections lives on our sections page .
- Throw the cylinder tall and even, then shape. Pull an even-walled cylinder first and only then swell the belly and ease in the shoulder. Even walls are not just craft pride here; they are how the finished pot survives decades of seasons intact.
- Cut the gallery while the rim is true. Split the rim and form the interior gallery in the same session the body is thrown, then measure it with calipers immediately, twice.
- Throw the lid to the number, same clay, same day. Off the hump or on its own bat, thrown a breath generous so the glazed fit lands easy. Check it on the leather-hard body before trimming and adjust while adjustment is still possible.
- Trim a foot that plants. A wide, flat, softly finished foot ring: this pot should sit like it intends to stay. Then dry the body and lid together, slowly, under loose plastic, so they arrive at bone dry as the matched pair they were born.
Building the urn by hand
No wheel, no problem: coil and slab construction has been building vessels of exactly this gravity for thousands of years, and it offers forms the wheel cannot. The sequence:
- Start from a slab base cut to plan. Draw the footprint, cut a sturdy slab base, and set it on a banding wheel or turntable so the build can grow evenly from all sides.
- Coil the walls up in patient rounds. Even ropes, each one scored, slipped, and truly blended into the last so the wall becomes one continuous body rather than a stack of seams. Our even coils page and coil blending page carry the technique; a grogged clay body carries the height.
- Paddle and compress as you climb. A paddle outside against a hand inside trues the curve, compresses the wall, and quietly erases the build. Rest the piece whenever the fresh rounds go soft; big hand-built work is a series of patient sessions, not one heroic afternoon.
- Build the gallery as a shelf coil. At the rim, attach an interior coil and shape it into a level gallery seat with a vertical inner wall, then verify it round and true with a template card cut to your lid’s diameter.
- Make the lid from a slab, flanged with a coil. Cut the lid from a firm slab against your template, dome it gently over a soft form if you like, and attach a coil flange underneath, sized to drop into the gallery with a little room for glaze. Fit it to the leather-hard body, adjust, then dry lid and body together, slowly, under loose plastic.
Personalizing: names, dates, and quiet surfaces
This is where an urn stops being a vessel and starts being a portrait. The full menu of surface techniques lives on our giant surface design guide ; these are the ones that serve this pot best.
- Inscriptions that outlast everything. A name and dates carved at leather hard, or inlaid mishima-style so the letters sit flush and razor sharp, become part of the clay itself. Practice the lettering on a test slab first; carve the real thing when your hand has the phrase memorized.
- Imagery in underglaze. A brushed motif, the mountains they loved, a curled-up cat, a fly-fishing line mid cast, painted in underglaze and sealed beneath a clear or softly transparent glaze. Photographic ceramic decals are also a real option, applied after the glaze fire in an additional cooler firing; talk to the front desk before planning one so you know what is currently possible.
- Choose a glaze that behaves. This is the pot for a proven, stable glaze in a quiet register, not a wild-motion experiment that might run over your carved letters. Test the exact glaze over the exact technique on a tile first; our glaze finder exists to shortlist candidates. Glaze the interior smooth and simple, keep the gallery’s mating surfaces clean for the seal, and let the outside do the speaking.
- Fired to last. The whole build rides our normal bisque and cone 5½ glaze firings, and a mid-fire stoneware taken to maturity is dense, tight, and built for generations on a shelf, in a niche, or in the ground.

The videos worth your evening
One video worth your evening
One complete build: a working potter making a real urn start to finish, with the care the object deserves. Reading gave you the duties; this is the craft, whichever path you take.
The path toggle above works here too: one complete urn build that everyone should watch, plus the deep dives for the path you chose. A note on why the page is mostly words anyway: the videos show the hands; reading is what carries the capacity math, the seal plan, and the seven decisions no video will make for you. Watch for the craft, read for the duty.
The ones we get asked, gently
Can any lidded jar serve as an urn?
Structurally, yes: an urn is a lidded jar that meets three extra standards. Verify the fired interior capacity against the one-cubic-inch-per-pound rule, make sure the lid seats deep enough to seal properly, and be sure the pot is fired to full maturity so it lasts. A beloved jar you already made can absolutely be promoted to the role once it passes those three checks; many of the most meaningful urns are.
How long does an urn take to make?
Weeks, honestly. The making itself is a session or a few, but slow drying is non-negotiable for a pot this important, and then the bisque and glaze firings add their own calendar. If a family needs a vessel sooner than clay allows, the kind answer is a temporary container now and your urn when it is truly ready, or an urn you wisely made ahead.
Is stoneware durable enough to bury?
Yes. A mid-fire stoneware taken to maturity in our cone 5½ glaze firings is dense, hard, and nearly non-absorbent, the same material family that survives centuries in the ground at archaeological digs. For burial, many cemeteries place the urn inside an urn vault regardless, so ask the cemetery about their requirements; for a niche or a shelf, fired stoneware will outlast all of us without trying.
What do I charge, or do I charge, for an urn commission?
There is no wrong answer, but decide before you start. Some potters make urns only as gifts; others treat them as their most serious commissions and price them accordingly, since the hours, the care, and the stakes are real. The one rule we would offer: never let an unclear arrangement hang over this particular pot. Settle it kindly up front so the making stays about the person it honors.
