A practical, ordered routine for washing cereal bowls, cleaning indigo slate glazes, and protecting handcrafted dinnerware from thermal shock.

Quick answer

Wash handmade ceramic bowls and plates by hand in warm water with mild dish soap, using a soft sponge. Rinse promptly and air-dry on a rack. Never move a piece straight from the freezer or refrigerator to a hot oven, and never pour boiling water into a cold bowl. This simple routine prevents most glaze damage and thermal shock.

Why handmade glaze needs a gentler routine

Factory dinnerware is often fired to a uniform, highly vitrified finish that tolerates rough handling. Handcrafted pieces can have subtle variations in glaze thickness, rim shape, and clay body. Those variations are part of the character, but they also mean abrasive cleaners and sudden temperature changes carry more risk. Treat each piece as a small, durable object rather than an indestructible one.

Daily washing without dulling the surface

Most days, warm water and a drop of mild dish soap are enough. Wash one piece at a time so bowls do not knock against each other in the sink. Use a soft sponge or nylon brush; avoid steel wool, scouring pads, and gritty powders that can scratch a glossy glaze. Pay attention to the foot ring underneath, where food residue and moisture tend to collect.

Drying and storage between meals

After rinsing, let pieces air-dry upside down on a dish rack so water does not pool in the base. If you stack bowls, place a soft cloth or felt pad between them to prevent rim-to-rim chipping. Store plates on edge or with a protective layer between each one. A little separation goes a long way toward keeping rims smooth.

Handling stains, odors, and stubborn residue

For coffee, tea, or tomato stains, make a paste of baking soda and water, apply it with a soft cloth, and let it sit for a few minutes before rinsing. Avoid bleach and harsh oxygen cleaners on colored glazes, since they can dull the surface over time. If a bowl retains an odor, a rinse of white vinegar followed by a thorough wash usually helps. Persistent stains on unglazed foot rings are normal and do not affect food safety.

Thermal shock: the mistake that cracks good pottery

Thermal shock happens when one part of a piece expands or contracts faster than another. The most common causes are pouring boiling liquid into a cold bowl, placing a chilled dish into a hot oven, or running a hot plate under cold water. Let pieces come to room temperature before extreme temperature changes. If you cook or bake with your dinnerware, preheat the oven with the dish inside rather than sliding a cold dish into a hot oven.

Step-by-step care routine

Scrape and rinse first: Remove leftover food with a silicone spatula, then rinse under warm water before washing. Common mistake: letting cereal or sauce dry hard on the glaze, which encourages scrubbing later. Checkpoint: no dried food left on the surface before soap is added.
Wash by hand with mild soap: Fill a basin with warm water and a small amount of mild dish soap. Wash one bowl or plate at a time with a soft sponge. Common mistake: using a sink full of hot water and letting pieces soak for hours. Checkpoint: water is comfortably warm, not steaming.
Rinse in warm water: Rinse each piece under running warm water until no suds remain. Common mistake: switching to cold water while the piece is still warm, which is a thermal shock risk. Checkpoint: rinse water temperature matches the wash water.
Air-dry upside down: Place bowls and plates on a dish rack so water drains away from the foot. Common mistake: drying with a stiff towel and twisting the rim, which can chip the glaze edge. Checkpoint: no standing water in the base.
Stack with protection: If you stack bowls or plates, put a soft cloth, felt pad, or paper napkin between each piece. Common mistake: nesting bowls tightly without a barrier, which grinds rims together. Checkpoint: pieces lift apart easily without sticking or scraping.
Handle temperature changes slowly: Let refrigerated or frozen pieces come to room temperature before adding hot food. Never pour boiling water into a cold bowl or run a hot plate under cold water. Common mistake: assuming all ceramic is equally resistant to sudden heat or cold. Checkpoint: no extreme temperature jump in either direction.

Product notes for these pieces

Cereal Bowl in Indigo / Slate: Designed in the 1960s, the Coupe Cereal Bowl boasts the clean, simple lines that have become a hallmark of the iconic collection. The gentle curve and rim are easy to wash by hand, but the glaze still benefits from a soft sponge rather than an abrasive pad.
Cereal Bowl in Cocoa / Fawn: Designed in the 1960s, the Coupe Cereal Bowl boasts the clean, simple lines that have become a hallmark of the iconic collection. The Cocoa / Fawn glaze shows less everyday staining than lighter glazes, so a mild soap wash is usually enough after cereal or soup.
Side Bowl in: Designed in collaboration with Christina Kim and Alice Waters of Chez Panisse, this versatile Side Bowl puts a laid-back Californian twist on classic French dinnerware. A bowl used for both serving and eating gets handled often, so hand-washing and careful stacking protect the rim from chips.
