Firstly, I want to tell you that the underglaze paint of the porcelain dinner set is safe, and the overglaze paint may be toxic.

To discuss the pattern of ceramic tableware, we must learn some knowledge of the production process.

Some professional vocabulary of ceramics

Underglaze painting: It is to use underglaze color to draw patterns on the green or bisque-fired body, and then cover it with a layer of glaze.

Pros and cons of underglaze color

Because you draw on the embryo before glazing, and then add a layer of glaze, the glaze will wrap the underglaze color inside, and you can see the feeling of the pigment slowly dyeing in the water. Glazing will also play a protective role, and the color will be well-preserved and will not fade over time. Therefore, we can now see many ancient underglaze-colored porcelains that are well preserved. Their patterns are well preserved.

Overglaze color

Overglaze painting: The fired porcelain is painted on the glaze and then put into the kiln at low temperature for the second time, including pastel porcelain, gold-painted porcelain, and enamel porcelain.

Overglaze decals: The fired porcelain is decaled on the glaze and then put into the kiln for a second time at a low temperature. Nowadays, many people use this process, which is relatively low-cost and has an advantage in price.

Pros and cons of  Overglaze color

The colors are bright, there are many kinds of color materials, and the operation process is simpler than underglaze color. However, the paint is not strong, and the patterns on the porcelain will be slowly worn away over time, or if it is corroded by acidic food, toxic elements such as lead and cadmium will be dissolved, making it feel bulging when touched.

Now we recommend some suggestions for safe identification and use of daily porcelain set:

  • When purchasing ceramic tableware, underglaze color is the first choice. Do not paint the inside of the tableware to avoid direct contact with food. (From the appearance, you can see that the overglaze color is raised, and you can touch it, while the underglaze color is smooth.) You can also check the specific details of the production process.
  • If after using the porcelain at home for a period of time, you find that the paint is peeling off or your nails can pick off the paint, you should pay attention to this. It can be judged to be an overglaze color, and it is recommended not to use it again.
  • It is not recommended to purchase very high-end gold-painted tableware. Gold-painted tableware is an overglaze coloring process, which is usually baked at a low temperature of 700-800 degrees (not all gold-painted tableware is necessarily bad. If it is baked at high temperature, use regular Gold water strokes are acceptable)
  • The purchased ceramic tableware should be soaked in 4% vinegar water and boiled first. This can remove most of the toxic substances and greatly reduce the potential harm of ceramic tableware to the human body;
  • The most important thing is the formal gold wholesaler, the supplier’s production qualifications, and whether there is a test report;
