Is Stoneware Dishwasher Safe?

Yes – most stoneware is dishwasher safe, but it depends on how it’s made.

The Quick Answer

Stoneware is generally safe to put in the dishwasher. High-fired, non-porous stoneware (like what we use at Ceramora) is built to handle daily use, including modern dishwashers. Just make sure the piece is labeled as dishwasher safe or made by a trusted ceramic brand.

What Makes Stoneware Dishwasher Safe?

Stoneware is a type of ceramic fired at high temperatures (usually over 2150°F / 1177°C), which makes it dense, strong, and less absorbent than other types of pottery. This high firing makes the surface vitrified – meaning it resists water and stains, a key reason it performs well in dishwashers.

However, not all stoneware is created equal:

• Handmade vs. Mass-Produced: Handmade stoneware might have unique glazes or surface textures that are more delicate. Always check if the maker states it’s dishwasher safe.

• Glaze Quality: Well-applied, high-temperature glazes protect stoneware in the dishwasher. Lower-fired or crackled glazes may degrade over time.

• Construction: Pieces with attached parts (like handles or bottoms glued on) might not hold up well unless they're expertly crafted.

Best Practices for Washing Stoneware

Even if your stoneware is dishwasher safe:

• Use the top rack when possible.

• Avoid sudden temperature changes (don’t go from freezer to dishwasher).

• Let pieces cool before rinsing or stacking.

Final Word

If you’re investing in high-quality stoneware (like the kind we handcraft in Portugal at Ceramora), it should absolutely be able to handle the dishwasher. Just treat it with a bit of care and it’ll last for years – whether you're using it at home or in a busy café.
