Beware: 4 Types of Bowls and Plates That May Have Harmful Effects

Are you looking for dishes and plates to add to your collection? Then you should be aware of the potential risks of certain types of dishes and plates, as these can be difficult to use and even hazardous to your health.


Plates and dishes are essential and commonly used utensils. The aesthetic appeal of beautiful plates and dishes can greatly enhance the enjoyment of a meal. However, there are certain types of plates and dishes that should be avoided, as they can be impractical to use and even detrimental to one’s health.

1. Plates with painted patterns on the glaze

Currently, there are two techniques for applying enamel coating to plates: underglazed enamel technique (involving patterns submerged under the glaze) and overglazed enamel technique (only coating the ceramic surface).

The coloring substances used in raised patterns can easily contaminate food when exposed to friction or high temperatures, leading to potential health risks. Many manufacturers opt for cheap chemical coloring powders that contain relatively high levels of heavy metals (such as lead, mercury, and cadmium) in order to cut costs.

Therefore, it is advisable to choose white plates or plates with submerged enamel patterns to avoid any release or impact of heavy metals.

When selecting enamel-coated plates, lightly tap the mouth of the plate with your hand. Plates that can withstand high heat are harder, have better colors, and possess more delicate features, resulting in a crisp sound. Conversely, a dull sound indicates lower temperature ceramics.

2. Stainless steel plates

Stainless steel plates are known for their durability and insulation properties, making them a popular choice among users. However, stainless steel plates are not suitable for storing certain acidic foods like tomatoes, oranges, lemons, or strong alkaline substances like baking soda, as they can corrode and potentially pose health risks when stored for extended periods.

It is especially important to be cautious when purchasing stainless steel plates as there are many low-quality options on the market that may contain heavy metals.

If you plan to buy stainless steel plates, opt for high-quality 2-layer 304 or 316 stainless steel to ensure the absence of health-related implications. Additionally, when cleaning stainless steel plates, avoid using scouring pads as they can cause scratches.

3. Plates without bases

Plates without bases are convenient for stacking and do not occupy much space in the dishwasher, attracting many individuals to choose them.

However, plates without bases may be visually appealing but are not always practical in terms of functionality. They can become hot and slippery while eating, making them prone to breakage. Therefore, careful consideration should be given before purchasing such plates.

4. Plates with rough and intricate patterns
