Tableware｜Overglaze colors look nice, but underglaze colors are easier to use
A beauty tableware, bowls, and dinner plates set can not only make food more delicious but also make dining more enjoyable. However, when you purchase a ceramic dinnerware set, do you know what kind of production process the tableware is made of? Do you know how to clean them? After all, these details about the selection of household tableware set are actually very important, and they affect your life and health.
Porcelain, Bone china, most of them are glazed
In the ceramic market, there are various types of tableware set. Such as melamine products for children that are resistant to falling and durable, and have stainless steel products that emphasize durability and do not care about appearance, but more people will still choose ceramic dinner plates set with various styles and patterns.
Most of the ceramic tableware used in daily life will be glazed and fired. “glaze” is a thin layer of glass on the ceramic body. The advantage of this thin layer is that it can isolate food and materials from direct contact with porcelain clay, and it can also form a water-oil insulation layer, which is helpful for daily cleaning and maintenance.
Porcelain tableware can meet basic usage needs with glazing and firing. But in order to be satisfied with consumers’ pursuit of beauty, the factory producers began to innovate on crockery dinner sets, paint various patterns, and gradually develop different technologies. Therefore, overglaze color, underglaze color, and glaze color are three common decoration techniques in the current market.
What are overglaze, underglaze and inglaze?
It is a way of painting according to the relative position of the pigment and the transparent glaze. The production of the three processes is still different. Overglaze will use various colors to paint on the glaze of the fired porcelain, and then it needs to be put into the kiln for the second time to solidify the pigment at a low temperature. Therefore, many materials can withstand the temperature, so porcelain often has more diverse color performance and patterns. However, due to the lack of protection of the transparent glaze layer, overglaze tableware is more prone to fading and falling off. Its durability and difficulty of cleaning will be significantly higher, so the labor-saving cleaning method of dishwasher is not suitable for overglaze tableware.
Similarly, we buy some tableware with gold line paintings in the market. The technical process of gold painting is to a certain extent the same principle as overglaze painting. It is also necessary to consider carefully when choosing to buy.
Underglaze painting is to paint various patterns on the formed blank, then add a layer of transparent glaze or other light-colored glaze, and then putting it into the kiln for high-temperature firing. Because the temperature is high, there are fewer materials that can withstand high temperatures, so underglaze painting is not as good as overglaze painting in terms of color display. In addition, adding an extra layer of transparent glaze to cover it has an advantage in preserving the color. Whether you clean it manually or put it in the dishwasher, there will generally be no problem.
The requirements for glaze-in-color craftsmanship are more stringent and the gas cost is also higher, so the market price may not be cheap.
Household tableware, underglaze color is the best choice
Based on the above understanding of the production process of ceramic tableware, we can easily judge that in daily life, underglaze color and glaze color are the safest choices. Considering the price point, underglaze color tableware is the best choice.
Overglaze color tableware, because of its uniqueness. If you need to use it in daily life, it is recommended to use a soft cloth, sponge, and other cleaning tools when cleaning. Dishwasher, steel wool, long-term soaking, and use of strong cleaning products are not suitable for this type of tableware.
