You've spent weeks perfecting your wheel-throwing technique in class, and now your mug collection is growing. The problem? Most people treat their handmade pottery the same way they treat dishware—and that's exactly how it gets chipped, discolored, or damaged. Proper ceramic care isn't complicated, but it does require understanding what your pieces can actually handle.
Know Your Glazing and Firing
Not all ceramics are created equal. The pieces you make in a beginner pottery class (typically $150–$300 for 6–8 weeks) are likely low-fire earthenware or mid-fire stoneware, depending on your instructor's kiln. This matters because low-fire pieces are more porous and fragile than stoneware or porcelain. Ask your pottery class instructor about the specific clay body and glaze used—this single detail changes your care routine entirely.
High-fire stoneware (cone 6 and above) is significantly more durable and food-safe than low-fire pieces. If you're unsure which category your work falls into, take a photo and ask your instructor. Most reputable pottery programs will document this information, and it's worth asking for details before you leave class.
Dishwasher vs. Hand Washing
Here's the reality: most handmade ceramics shouldn't go in the dishwasher, even if they're glazed. High water pressure, intense heat cycles, and abrasive detergent can cause glaze crazing (tiny cracks) and eventually break down the seal on lower-fired pieces. Hand washing in warm soapy water is your safest bet.
Use a soft sponge, never scour pads. A standard kitchen sponge works fine; metal scouring pads will scratch glazes and chip unglazed areas. Dry your pieces immediately to prevent water spots on certain glazes. For pieces with metallic glazes (gold, silver, or luster finishes), hand washing is non-negotiable—dishwashers will dull and strip them.
Storage and Display Tips
Stacking ceramics puts stress on bases and rims. If you're storing pieces, use felt pads or cloth between stacked items. Store dishes vertically in a cabinet rather than stacked flat when possible—this reduces breakage risk and makes pieces easier to access.
For display, keep ceramics away from:
- Direct sunlight (can fade glazes over time)
- High-humidity areas like bathrooms (promotes mold and mineral deposits)
- Heat sources like radiators or ovens (temperature shock weakens glazes)
- High-traffic areas where pieces might get knocked over
Handling Chips and Cracks
A small chip on the rim? You have options. Food-safe epoxy adhesive (around $8–$15 at hardware stores) can hold pieces together temporarily, but this isn't a permanent solution for functional pottery. For structural cracks that go all the way through, the piece is essentially done as dishware.
Consider repurposing cracked functional pieces as plant holders, pencil cups, or decorative objects. If you want professional repair, Japanese kintsugi (gold seam welding) runs $100–$400+ depending on complexity, but that's a specialty service—ask pottery studios if they have kintsugi recommendations in your area.
Preventing Thermal Shock
Never go straight from the oven to a cold sink. Temperature swings cause fine cracks invisible to the eye that eventually fail. If you're using your handmade pottery functionally, let it cool naturally before washing. Same rule applies to cold items going into a warm oven.
Regular Maintenance
Wipe glazed surfaces monthly with a soft, dry cloth to prevent dust buildup. For stubborn mineral deposits from hard water, a 50/50 vinegar-and-water solution works, but test it on an inconspicuous area first.
If pieces start developing unpleasant odors (common in porous earthenware), soak them in baking soda solution overnight, then rinse thoroughly. This neutralizes trapped bacteria and mineral odors.
Finding Quality Care Guidance
The best care advice comes directly from the person who made your piece. If you're taking pottery classes, build a relationship with your instructor—they know exactly what your work can handle. When hiring pottery classes or looking for additional guidance on ceramic finishing, Mercoly makes it easy to compare trusted pottery providers and find instructors who prioritize teaching proper care practices as part of their curriculum.
Frequently Asked Questions
Q: Can I use my handmade mug for hot liquids? Only if it's mid-fire stoneware or higher and fully glazed—ask your pottery instructor to confirm. Low-fire earthenware absorbs liquid and can fail with thermal shock.
Q: How do I remove hard water stains from my ceramics? Soak the piece in white vinegar for 30 minutes, then scrub gently with a soft sponge and rinse completely.
Q: Is handmade pottery food-safe? Only if the clay body is food-safe (stoneware or porcelain fired at cone 4 or higher) and the glaze contains no toxic materials—your pottery class instructor should confirm this before you use pieces functionally.
