Stoneware is one of the most durable dinnerware materials available — but only if you treat it right. Here's everything you need to know to keep your pieces looking beautiful for years.
Well-cared-for stoneware can last a lifetime. Poorly cared-for stoneware can crack, stain, or lose its glaze in as little as a year. The difference comes down to a handful of habits that are easy to adopt once you understand why they matter.
The good news is that glazed stoneware — like all vancasso pieces — is genuinely low-maintenance. Fully glazed surfaces are non-porous, so food doesn't seep into the clay body, and the glaze itself resists most stains.
Yes — with one important caveat. Fully glazed stoneware is completely dishwasher safe and can handle high-heat wash cycles without issue. Unglazed or partially unglazed stoneware (common in rustic or artisan pieces with bare clay bottoms) should be hand-washed, because water can penetrate the unglazed clay body and cause cracking over time.
All vancasso stoneware pieces are fully glazed, including the base. This makes them safe for the dishwasher on any cycle — including heated dry settings.
Fill the mug with a solution of 1 tablespoon white vinegar per cup of warm water. Let it soak for 30 minutes.
If the stain remains, make a paste of baking soda and a few drops of water. Apply to the stain with a soft cloth and rub gently in circular motions.
Rinse thoroughly with warm water and wash normally. For stubborn stains, repeat once before trying any stronger solution.
These pigment-heavy foods can temporarily stain glazed surfaces. In most cases, soaking in warm soapy water for 20–30 minutes is enough. For persistent stains, apply a thin layer of baking soda paste, cover with plastic wrap, and leave overnight. The mild abrasion of the baking soda will lift the stain without damaging the glaze.
Stoneware is one of the few dinnerware materials that transitions well from the refrigerator to the oven, making it ideal for baking and reheating. Follow these guidelines:
You may notice fine hairline patterns developing in the glaze of your stoneware over time. This is called crazing and is a natural characteristic of hand-glazed ceramics. It occurs when the glaze and clay body expand and contract at slightly different rates during heating and cooling.
Crazing on glazed stoneware is purely cosmetic — it does not affect the food safety, structural integrity, or function of the piece. Many pottery enthusiasts actually prize crazed glazes for their aged, artisan appearance.
True structural cracks — cracks that penetrate through the clay body, not just the glaze — are a different matter. If a piece develops a full crack that goes through the wall of the plate or bowl, it should be retired from use, as bacteria can harbor in the crack and it may eventually break under load.
Most stoneware chips happen not during use but during storage. Here's how to prevent it:
Quality glazed stoneware should last 10–20 years with proper care. Replace a piece if you notice:
Surface scratches from cutlery (the grey metallic marks sometimes left by forks and knives) are purely cosmetic and can often be removed with a baking soda paste. They don't indicate that the glaze is failing.
Yes — fully glazed stoneware like all vancasso pieces is completely dishwasher safe. Use any cycle. Unglazed areas should be hand-washed to prevent water absorption.
For most stains: soak in warm soapy water for 30 minutes. For stubborn stains: apply a baking soda paste, let sit, then scrub gently with a non-abrasive sponge. White vinegar works well for coffee and tea stains.
These are called crazing and are a natural, cosmetic characteristic of hand-glazed stoneware. They don't affect safety or function. True cracks through the clay body are different — those pieces should be replaced.
Yes, up to 450°F (230°C). Always place cold stoneware in a cold oven and bring them up to temperature together. Avoid going directly from freezer to oven — the thermal shock can crack the piece.
With proper care, quality glazed stoneware lasts 10–20 years and sometimes much longer. The main enemies are thermal shock, abrasive scrubbing, and improper storage that causes chips.
