Handmade ceramics are wheel-thrown or hand-built clay objects, typically stoneware, earthenware or porcelain, fired and often glazed by an individual maker. Because each piece is unique and not mass-produced, it needs gentler care to keep its patina, colour and shape over decades of use.
Know what type of ceramic you have: Stoneware is the most durable and usually dishwasher-safe. Earthenware is more porous and needs hand-washing. Porcelain is delicate but hard. Unglazed or partially glazed pieces (often the case with handmade vases and planters) absorb water and stain easily, so always treat them as hand-wash-only.
Hand-wash with warm, not hot, water: Sudden temperature changes cause thermal shock, the most common cause of cracks. Run a basin of warm water with a few drops of mild washing-up liquid. Avoid soaking handmade pieces; wash and rinse one at a time with a soft sponge.
Skip the dishwasher for anything precious: Even dishwasher-safe glazes dull faster with repeated cycles, and the heat can craze hand-applied glazes over time. For everyday stoneware mugs and bowls it's usually fine, but always hand-wash signed, unglazed or vintage pieces.
Dry immediately and thoroughly: Air-drying leaves water marks and, for unglazed clay, encourages mildew. Pat each piece dry with a soft cotton tea towel and leave it upright on a dish rack for 10–15 minutes before putting it away.
