How to tell if pottery is handmade

Three ways a pot gets made

Almost every ceramic object you can buy was made one of three ways. It was thrown on a potter's wheel, spun and pulled up by hand. It was hand-built from pinched, coiled or rolled slabs of clay. Or it was formed in a mold — either slip-cast, where liquid clay is poured into an absorbent plaster mold and left until a wall builds up, or jiggered, where a spinning mold and a template press soft clay into shape. Jiggering is how plates, cups and bowls are mass-produced on a mechanized wheel.

Molds are not a mark of dishonesty. Slip casting is used by individual potters for one-off work as well as by industry, and a small-studio cast piece can be lovely. But a molded piece is not thrown, and a listing that says hand-thrown should mean it. Everything below is about telling those apart from the object, or from good photographs of it. The other thing worth reading off a listing is what is in the glaze rather than how the pot was formed — lead-free pottery has the limits and the pieces that deserve suspicion.

Turn it over: the foot

The foot is the unglazed ring the pot stands on, and it is where a thrown piece usually gives itself away. After throwing, a potter typically turns the piece upside down on the wheel and trims the base with a tool, which leaves concentric tool marks and a foot ring that varies slightly in width. Many potters also sign, stamp or mark the base there.

A molded piece tends to have a base that is perfectly regular and smooth, because the mold made it rather than a tool. Neither observation is conclusive on its own — some potters sand their feet smooth, and some molds are made to look trimmed — but a trimmed, signed foot is the strongest single piece of evidence a pot can carry.

Throwing rings and walls

Run a finger up the inside of a thrown mug or bowl and you will often feel faint spiral ridges — throwing rings, left by the potter's fingers as the clay was pulled up. Some potters smooth them away and some leave them on purpose. Thrown walls also vary a little in thickness from base to rim, and two thrown pieces sold as a pair will differ slightly in height and weight.

Slip-cast ware tends toward the opposite: uniform wall thickness, sometimes very thin, and a very smooth exterior. Look for seam lines where the parts of the mold met — a faint vertical line down the side, or along the length of a handle. A mold seam is the clearest sign that a piece was cast, and it often shows in close-up photographs.

Handles and glaze

A thrown mug's handle is usually pulled — drawn out from a lump of clay by hand — and then attached, which often leaves a small thumb mark or a smoothed joint where it meets the body. Molded handles tend to be identical from mug to mug and can carry a seam line of their own.

Glaze is harder to read. A running or pooling glaze that looks different on every piece is good evidence of kiln variation, and the turquoise mug on this page is an example of exactly that. But even glaze is also what a skilled potter works hard to achieve across a set, so treat glaze as supporting evidence rather than proof in either direction.

What does not prove anything

• Imperfection. Factory ware can be designed to look irregular, with deliberate drips and wobbles. A wobble alone is decoration, not evidence.
• Words in the title. Artisan, rustic and handcrafted cost nothing to type. Spotting resold mass production covers the listing signals that do mean something.
• Hand-painted. A factory blank can be painted by hand. That is real handwork on the decoration, but the pot itself may still be molded.
• Price alone. A very low price is a warning sign for thrown work, but a high price is not a guarantee.

What the evidence looks like on a listing

Online, you are reading photographs rather than holding the pot, so a good listing does the turning-over for you. The makers worth buying from name the method (wheel-thrown, hand-built), name the clay body, photograph the foot, and say plainly that pieces vary. Some go further. The vase below is signed on the base by the potter, and the small-bowl set in our stoneware vs porcelain comparison comes with a note that every set is thrown and glazed individually, so the colors will not match the photo exactly. That kind of note is a feature: a factory has no reason to warn you.

The four pieces below each carry at least one of those signals, stated on the listing rather than implied, and every card also says whether it sits on Amazon Handmade.

Why it matters for a gift

A thrown pot takes skilled time at the wheel, trimming, usually two firings and a real failure rate, and its price reflects that. When you pay for that, you should get it. Knowing how to read the foot and the walls means you can tell whether you did — and it means the person who receives the mug can turn it over and find a signature rather than a sticker.

What handmade actually means covers the wider question across every craft, the handmade mugs and handmade vases roundups apply these checks to specific pieces, and handmade pottery care covers what to do once it arrives.
