Can stoneware be placed in a dishwasher?

Stoneware is a popular choice for kitchenware due to its durability, versatility, and aesthetic appeal. It is a type of pottery that is fired at extremely high temperatures, resulting in a dense and strong ceramic material. However, when it comes to cleaning stoneware, many wonder if it is safe to put it in the dishwasher. In this article, we will discuss whether stoneware can be safely placed in a dishwasher and provide some tips for maintaining and caring for your stoneware.

Understanding Stoneware and its Properties

Stoneware is known for its ability to withstand high temperatures, making it suitable for use in ovens, microwaves, and broilers. It is made from a type of clay that contains a higher percentage of flux materials and is fired at temperatures above 2,100°F (1,150°C), resulting in a solid, non-porous material. This firing process makes stoneware stronger, more chip-resistant, and less absorbent than other types of pottery.

The Dishwasher Dilemma

Many modern dishwashers feature multiple settings with varying temperatures and cycles, making it convenient for cleaning a wide range of kitchenware. However, the high heat, powerful jets of water, and harsh detergents used in dishwashers can potentially damage certain types of materials, including stoneware. While stoneware is generally considered dishwasher safe, there are a few factors to consider before tossing it into the dishwasher.

The Impact of Temperature on Stoneware

Although stoneware is highly resistant to thermal shock, extreme temperature changes can cause it to crack or break. Therefore, it is important to check if your stoneware is labeled as “oven-safe” before placing it in the dishwasher, as this indicates that the stoneware can withstand high temperatures. Additionally, avoid placing very hot stoneware directly into a dishwasher filled with cold water, as the sudden temperature change may be too much for the material to handle.

Consider the Glaze

Stoneware often features a glaze, which is a glass-like coating that provides not only an attractive finish but also helps to seal the clay underneath, making it more resistant to staining and absorption. However, not all glazes are created equal, and some may not be dishwasher safe. If your stoneware has a delicate or fragile glaze, it is best to wash it by hand to prevent damage.

Protecting Your Stoneware in the Dishwasher

If you decide to put your stoneware in the dishwasher, there are a few steps you can take to minimize the risk of damage:

1. Load the dishwasher carefully: Place stoneware pieces away from other items that could potentially scratch or crack them. It is also a good idea to space them out to allow for adequate water circulation.
2. Avoid overcrowding: Overcrowding the dishwasher can lead to dishes banging into each other, which increases the likelihood of chipping or breaking. Be mindful of leaving enough room for each piece of stoneware to remain secure.
3. Use a gentle cycle: Opt for a gentle or delicate cycle with a lower temperature setting when cleaning your stoneware in the dishwasher. This reduces the risk of any sudden temperature changes and decreases the exposure to harsh water jets.
4. Skip the heated drying cycle: After the dishwasher has finished its cycle, allow your stoneware to air dry or gently pat it dry with a soft towel. Avoid using the heated drying option as the high heat can be detrimental to the longevity of your stoneware.

Caring for Your Stoneware

To prolong the life of your stoneware, it is essential to follow a few care tips:

1. Handwashing: If you have any doubts about your stoneware’s dishwasher safety, it is safer to wash it by hand. Use warm water, mild dish soap, and a soft cloth or sponge to clean your stoneware. Avoid abrasive materials that can scratch the surface.
2. Avoid sudden temperature changes: Allow your stoneware to cool down gradually after being exposed to high temperatures, such as when removing it from the oven. Placing hot stoneware on a cool surface or immersing it in cold water can cause it to crack.
3. Store properly: To prevent scratching or chipping, stack your stoneware with protective padding or use felt or silicone pads between stacked pieces. Avoid stacking excessively heavy items on top of delicate stoneware.

While stoneware is generally dishwasher safe, it is important to consider factors such as temperature changes and the type of glaze used before placing it in the dishwasher. If in doubt, handwashing is always a safe option. By following proper care tips and using caution when cleaning and handling stoneware, you can ensure its longevity and continue enjoying its beauty and functionality for years to come.
