A pottery class ends with clay under your fingernails and something warm, slightly lopsided and entirely yours in your hands. The awkward part starts at home. The mug holds tea but beads moisture at the base. The planter has no drainage hole. The bowl you love sits on a shelf because you don't quite trust it with soup. None of that means the piece is a failure. Workshop pottery can become real tableware and real decoration; it just needs a few sensible decisions, a little patience, and an honest look at what came out of the kiln.
Find Out Exactly What You Brought Home
Before you plan a life for the piece, learn its biography. Most workshop instructors are happy to answer questions at the end of the last session, and it is worth asking while the details are still fresh: Which clay body is this? What temperature was it fired to? Which glaze went on it, and is it rated for food contact?
Earthenware fired at lower temperatures stays slightly porous even when glazed, so it is more likely to stain, craze and hold warmth from the outside in. Stoneware and porcelain, fired higher, are denser and generally more forgiving. Glaze fit matters just as much as firing temperature, though. A glossy surface can still develop a fine web of cracks, and a matte one can be perfectly sound.
Turn the piece over and look at the base. A waxed or wiped foot, a maker's mark, a slightly rougher ring where it sat on the kiln shelf — all of it tells you how it was made. Write the clay, the glaze name and the firing on a sticky label underneath, or keep a note in your phone. In two years, when you want a second mug to match, that note will save you a lot of guesswork.
Give It a Fortnight Before It Earns a Place
Pottery is not finished when you carry it to the car. A piece that survived the kiln can still crack if it cools too quickly or is put straight to work. Let new work sit indoors for a week or two, away from radiators, cold windowsills and direct sun, before you fill it with anything.
Then run a simple leak test. Stand the piece on a dry paper towel, fill it with water, and leave it overnight. A faint damp ring in the morning means the body is porous and the glaze has a gap somewhere. That is useful information, not a disaster — it moves the piece from the kitchen shelf to the hallway shelf.
For anything headed for hot drinks, fill it with boiling water, set it on a dry surface and watch the outside for a minute. Listen, too. A soft ticking or crackling sound often means the glaze is crazing as it expands. Crazed glaze is still beautiful, but those fine lines are not a watertight barrier, and they can trap residue. Keep crazed pieces for dry use, or give them a liner.
Finish the Feet, Rims and Surfaces
Smooth the sharp bits
Sharp rims and gritty feet are the most common workshop leftovers. Wet-sand them with silicon carbide paper, starting around 220 grit and finishing with 400. Keep the paper wet, work outdoors or over a bowl of water, and wear a mask. Clay dust is a genuine lung irritant, so never dry-sand pottery in the kitchen.
Level a wobbly base
Resist the urge to grind a foot ring flat unless you know exactly how thick the base is. Instead, add small self-adhesive felt pads or thin silicone dots at three points. The piece will sit steady on a table without scraping it, and the fix takes about a minute.
Seal what should be sealed
On an unglazed exterior — the outside of a planter, the base of a sculptural piece — a thin coat of beeswax or a stone sealer slows staining and water marks. Never seal the inside of a planter you want to drain, and never seal a surface that will touch food.
Decide How Far to Trust It With Food and Heat
If you cannot confirm that the clay and glaze are rated for food contact, use the piece for dry goods, wrapped food or fruit you peel. A small glass or ceramic liner turns a doubtful vessel into a perfectly good serving bowl. Be cautious with acidic foods such as tomato sauces, citrus and vinegar in any unconfirmed or crazed glaze.
A few habits protect workshop pottery from the most common damage:
- Hand wash and dry promptly. Dishwashers are harsh on glaze edges and detergents wear down unglazed feet.
- Avoid thermal shock. No freezer to oven, no cold water into a hot pot, no empty mug in the microwave.
- Never use pottery on a hob or over an open flame, and treat oven use as a question for your instructor, not an assumption.
- Skip the microwave for any piece with metallic lustre, gold trim or an uncertain glaze.
- Do not drink from chipped rims; the edge can cut and the chip will keep growing.
If a piece has sentimental value and you want certainty about its safety, ask the studio or a ceramics supplier rather than guessing.
Give It a Job That Suits Its Character
The best home for a workshop piece is usually the one that plays to its strengths. A thick-walled, slightly rustic bowl is a fine key dish; a thin, elegant cup with a crazed glaze is a pen pot. A few reliable roles:
- Planter: drill nothing yourself unless the studio confirms the body can take it. Set a plastic nursery pot inside as a cachepot, or use a piece with a drainage hole and a saucer.
- Kitchen crock: utensils, wooden spoons, whisks. Weight matters here; a broad base stops tipping.
- Soap dish: only with drainage slots or a raised base, otherwise the soap dissolves into a puddle.
- Spoon rest or garlic keeper: small, sturdy, easy to rinse.
- Candle holder: use a metal or glass votive cup inside, and keep the flame well clear of the rim.
- Catch-all: keys, coins, hairpins, the small things that migrate across a hallway.
Care, Repair and Knowing When to Retire a Piece
Wash glazed work by hand with a mild soap, rinse well and let it air dry upside down on a rack. Avoid stacking heavy pieces inside delicate ones, and lift rather than slide pieces across shelves, since grit under a base scratches both pottery and furniture.
Hairline cracks are a signal to stop using a piece for liquids. A food-safe epoxy can hold a decorative repair together, and visible mending with lacquer or coloured resin is a legitimate look, but repaired cracks are difficult to keep clean and should stay away from food. Retire anything that smells musty after washing, flakes glaze at the rim, or has a crack that moves when you press it.
A Five-Minute Check Before It Goes on the Shelf
The transition from class souvenir to household object takes less time than you would think. Run through this list once and then stop worrying about it:
- Clay, glaze and firing written down and stuck underneath.
- Two weeks of settling, then a leak test and a hot-water test.
- Sharp edges wet-sanded, wobble corrected with felt pads.
- A job chosen to match the piece's weight, finish and porosity.
- A shelf spot away from radiators, direct winter sun and the edge of a table.
- A short care note taped inside the cupboard if the piece lives in a shared kitchen.
Do that, and the mug you made on a Tuesday evening becomes the one you reach for every morning — which is, after all, the point of learning a craft in the first place.
