Why
Stoneware is a dense, vitrified ceramic fired at high temperatures, making it durable and non-porous. However, the dishwasher's high heat (up to 75°C/170°F) and harsh alkaline detergents can cause thermal shock, leading to cracking or crazing (fine surface cracks) if the stoneware is not fully vitrified or if it undergoes rapid temperature changes. Additionally, metallic trims or painted decals will fade, peel, or tarnish over time due to the alkaline detergent and heat. The manufacturer's care instructions often recommend hand washing to preserve the finish, but many brands state that stoneware is dishwasher safe if placed on the top rack away from the heating element. The main failure modes are: crazing (from thermal stress), decal peeling (from detergent), and metallic trim degradation (from heat and chemicals). The body is typically safe, but lids (if glazed) may be more prone to chipping, and any metal components (like handles or knobs) should be hand washed.
How do you wash stoneware casserole dish?
- Allow the casserole dish to cool completely before washing to avoid thermal shock.
- If there is metallic trim or decals, hand wash only with a soft sponge and mild dish soap.
- For plain stoneware, place on the top rack of the dishwasher, away from the heating element.
- Use a gentle cycle with low heat and avoid high-temperature drying cycles.
- Remove promptly after the cycle ends to prevent water spots or mineral deposits.
- For stubborn food residue, soak in warm water with baking soda before washing.
- Dry thoroughly with a soft cloth before storing.
What happens if you put stoneware casserole dish in the dishwasher?
If you put a stoneware casserole dish in the dishwasher, the first few washes may not show any visible damage, especially if it is high-quality and fully vitrified. However, over repeated washes, you may notice crazing (a network of fine cracks in the glaze) due to thermal stress from the high heat and rapid temperature changes. If the dish has metallic trim or painted decals, these will begin to fade, peel, or discolor after just a few cycles. The alkaline detergent can also dull the glaze over time, making it appear cloudy or etched. In extreme cases, thermal shock can cause the dish to crack or break, especially if it is cold when placed in a hot dishwasher. The damage is primarily cosmetic for the body (crazing, dulling) but can become functional if cracks develop, as they can harbor bacteria and weaken the dish. Metallic trim damage is purely cosmetic but permanent.
Frequently asked questions
- Can stoneware go in the microwave?
- Yes, most stoneware is microwave-safe as long as it has no metallic trim. However, avoid rapid temperature changes (e.g., from fridge to microwave) to prevent thermal shock.
- What water temperature can stoneware withstand?
- Stoneware can typically withstand temperatures up to 400°F (204°C) in an oven, but sudden temperature changes (e.g., from cold water to hot oven) can cause cracking. In the dishwasher, avoid high-heat cycles.
- Will the glaze peel over time?
- The glaze itself does not peel, but if the dish is not fully vitrified, the glaze may craze (develop fine cracks) due to thermal stress. Metallic or painted decorations can peel or fade with dishwasher use.
