Is Glazed Pottery Safe to Wash in the Dishwasher?
Glazed pottery may be washed in the dishwasher. Glazed pottery after everyday usage in the dishwasher retains gloss, and colors remain vibrant. Even glazed pottery in matte glazes does not wear out in the dishwasher. Glazed pottery is tough, long-lasting, and dishwasher safe. Avoid drastic fluctuations in temperature and bumping pottery into each other while in the dishwasher for safety.
Now all that being said, I do not wash any pottery I care about in the dishwasher.
Dishwasher Safe Pottery Glazes
Mid-range glazes for use with cone 5/6 fired are dishwasher safe. One of my favorite glazes is from Mayco. I can find Mayco Stoneware Glazes in a wide range of hues, textures, and opaque features. Stoneware glazes are gloss, matte, ice, opal, linen, and crystals. And for even more color variety, you can optionally add a light or dark flux. I like Mayco because of its wide firing glazing range and is compatible with stoneware.
All properly fired glazes are absolutely dishwasher safe. However, there is the possibility that you have pottery that was fired incorrectly. Glazes fired incorrectly (not at the right temperature) will not be as durable and, as a result, will break down over time after being washed in the dishwasher. In addition, you may see signs of wear not related to being used in the dishwasher. This is because someone did not correctly fire the glaze.
Dishwasher Safe Plates And Pottery
I have found based on my experience is that potter glazes hold up well, but the stoneware itself does not. The stoneware tends to chip in the dishwasher due to improperly stacking plates or cups where they can accidentally bang against each other. I have some Spode Christmas plates, for example, that I will never put into the dishwasher because of this.
How different are Clay and Terracotta? The clay is an ingredient, but terracotta is a molded and fired clay. Terracotta articles are typically made of biological clay, although terracotta clay is connected with the word with the color. Low-temperature burning of terracotta materials provides a porous and permeable surface.
I have some cheaper stoneware plates and pottery I am not afraid to load into the dishwasher because if they chip over time, I’ll just purchase more. For pottery I care about, it’s gets hand-washed.
How Can I Tell If My Ceramic Dish Is Dishwasher Safe?
If handmade ceramics are fired properly, they are dishwasher safe. If not, then you will notice the glaze start to lose its gloss. Most ceramics will say on the back if they are dishwasher safe.
I create both ceramic plates and sculptures and all of my artwork is fired correctly and I only use glazes that are durable and are wear resistant. I have been using my pottery for decades with no problems of glaze wearing out.
Some ceramics are created for decorative use only. These are antiques and made specifically for decoration. If you know the history of your pottery, it will help you decide on how you want to care for it. You made decide to error on the side of caution and wash antiques by hand. Other pottery where you know the manufacture and are willing to take more chances on the dishwasher may be the way to go.
Dishwasher Safe Summary
Glazed pottery is tough, long-lasting, and dishwasher safe. Avoid drastic fluctuations in temperature and bumping pottery into each other while in the dishwasher. Glaze keeps its gloss, and colors remain vibrant after washing. Even glazed pottery in matte glazes does not wear out in the Dishwasher.
But chipping is another story. Pottery put into the dishwasher is likely to get chipped as it gets banged into each other.
