How to Tell if Pottery Is Dishwasher Safe
To determine if pottery is dishwasher safe, it is important to check with the potter or manufacturer for specific information.
Generally, pottery made from earthenware clay is not dishwasher safe, while stoneware or porcelain pottery can be dishwasher safe if fired and glazed correctly.
Dishwasher safe means that the pottery can withstand the heat, water, and detergents in the dishwasher without being damaged.
Dishwashing cycles are more aggressive to pottery than regular handwashing, and the pH of dishwasher detergents can dissolve glazed surfaces.
It is also important to note that not all glazes are created equal in terms of dishwasher safety.
To test pottery for dishwasher safety, it can be submerged in water to see if it absorbs any moisture.
Additionally, pottery with delicate sculpted details, metallic lusters, or decals should not be put in the dishwasher.
Keeping these considerations in mind, looking for words like “Dishwasher Safe” or a dishwasher safe symbol, stamp, or label on the pottery can help determine if it is suitable for dishwasher use.

Earthenware Clay Pottery and Dishwasher Safety
Pottery is a beloved art form that has been used for centuries to create beautiful and functional pieces. However, when it comes to using pottery in the dishwasher, there are certain considerations to keep in mind. Pottery made from earthenware clay, also known as terracotta, is usually not dishwasher safe. The porous nature of this type of clay makes it susceptible to damage under the intense heat, water, and detergents used in the dishwasher. The harsh environment of the dishwasher can cause the earthenware to crack, warp, or even break. To ensure the longevity of your earthenware pottery, it is advisable to wash it by hand.
Factors Affecting Dishwasher Safety for Pottery
When determining if pottery is dishwasher safe, there are several factors to consider. One of the key factors is the type of clay used. Stoneware, which is fired at a higher temperature than earthenware, is generally more suitable for dishwasher use. Porcelain, known for its durability, can also be dishwasher safe if fired and glazed correctly.
Another important factor is the glaze used on the pottery. Glazes can vary in their ability to withstand the aggressive environment of the dishwasher. Some glazes may be watertight and resist damage, while others may be more prone to deterioration.
Other factors to consider include the corrosiveness of the dishwasher detergent, the hardness of the water, and the maximum temperature of the dishwasher. Dishwashing detergents typically have a pH of around 10, which can dissolve glazed surfaces over time. Water hardness, which refers to the mineral content of the water, can also affect the longevity of pottery in the dishwasher. Additionally, some dishwashers have higher maximum temperatures that can potentially damage delicate pottery.
Taking these factors into account is crucial when assessing the dishwasher safety of pottery.
Glaze and Clay Body Considerations for Dishwasher Safe Pottery
The interplay between the glaze and clay body of pottery is crucial for determining its dishwasher safety. The clay body refers to the type of clay used to make the pottery, while the glaze is the outer coating applied to enhance its appearance and functionality. The fit between the glaze and clay body must be compatible to ensure a strong bond and prevent water from seeping through. If the fit is poor, the glaze may crack or flake off, compromising the dishwasher safety of the pottery.
It is also important to note that not all glazes are created equal in terms of dishwasher safety. Some glazes may be more resilient and withstand the dishwasher’s aggressive environment, while others may deteriorate or discolor over time. Glazes labeled as “food safe” are specifically formulated to be suitable for contact with food and drink. However, this does not necessarily mean they are dishwasher safe. To ensure the dishwasher safety of pottery, it is advisable to check with the potter or manufacturer for specific information regarding the glaze and clay body.
Testing and Checking for Dishwasher Safety of Pottery
If you are unsure whether your pottery is dishwasher safe, there are a few tests you can conduct to determine its suitability. One method involves submerging a small portion of the pottery in water for an extended period, such as overnight. If the pottery absorbs water or shows signs of damage, it is not dishwasher safe. Another method is to examine the pottery for any visible cracks, chips, or glaze flaking. Even if pottery is labeled as dishwasher safe, it should be periodically checked for signs of cracking or damage.
It is important to note that dishwasher-safe pottery should still be handled with care. Delicate sculpted details or thin walls may be prone to breakage under the aggressive dishwasher conditions. To preserve the beauty and integrity of pottery, especially if it is artisan-made, handwashing is often recommended. Taking the time to wash pottery by hand can help maintain its original appearance and prolong its lifespan.
Dishwasher Safety and Various Types of Pottery
Different types of pottery have varying degrees of compatibility with dishwashers. Pottery made from earthenware clay is generally not ideally suited for dishwashers due to its porous nature. Stoneware, on the other hand, can handle being in the dishwasher better, especially if fired and glazed correctly. Porcelain pottery, known for its strength and durability, can also be dishwasher safe if fired and glazed properly.
It is important to be cautious with certain types of pottery in the dishwasher. Pottery with metallic lusters or delicate decals should not be put in the dishwasher, as the intense cleaning process can damage or fade these decorative elements. Exposed unglazed areas of pottery can become discolored over time with repeated dishwasher use. Additionally, glossy glazes may lose their shine over time as a result of dishwasher cleaning. Understanding the characteristics and limitations of different types of pottery is essential for determining their dishwasher safety.
Guidance and Labels for Determining Dishwasher Safe Pottery
To determine if a piece of pottery is dishwasher safe, it is helpful to look for specific guidance or labels. Commercial pottery often has a symbol indicating its dishwasher safety. This symbol typically resembles a wine glass or a plate with water droplets, indicating that the pottery is safe for use in dishwashers. Additionally, some artisans may explicitly label their pottery as dishwasher safe. However, it is important to note that not all manufacturers or potters test their glazes for dishwasher safety.
If you are uncertain about the dishwasher safety of your pottery, it is always best to contact the potter or manufacturer directly for guidance. They will have specific knowledge about the clay body, glaze, and firing techniques used in the creation of the pottery. Their expertise and insight can help you make an informed decision about whether the pottery is suitable for dishwasher use.
Determining if pottery is dishwasher safe requires consideration of several factors. Earthenware clay pottery is generally not dishwasher safe due to its porous nature. Factors such as the type of clay used, the glaze applied, and various dishwasher conditions can affect the dishwasher safety of pottery. Testing and checking for signs of damage, as well as understanding the limitations of different types of pottery, are also crucial. Labels or symbols indicating dishwasher safety can provide guidance, but it is always best to consult the potter or manufacturer for specific information. With proper care and attention, you can enjoy your pottery for years to come, whether you choose to wash it by hand or in the dishwasher.
