How to judge the quality of white coated mug enamel

يونيو 7, 2024

The enamel of the 10oz classic white ceramic mug generally refers to the paint covering the surface of the ceramic vessel. This paint is fired at high temperatures to form a transparent or tinted glass-like surface. The characteristics of the enamel determine the appearance, performance and cleaning convenience of the white coated mug.

The impact of enamel on mugs:

1.Wear resistance and stain resistance. After the glaze is covered on the ceramic surface, it can significantly enhance the wear resistance and stain resistance of the ceramic, making the mug more durable and less likely to be damaged by scratches or stains.

2.Aesthetics. Glazes can present a rich variety of colors and textures, making them more visually beautiful and attractive. Different enamels can create different visual effects to meet the diverse aesthetic needs of consumers.

3.Cleanability. The glaze surface is smooth and does not easily absorb dirt. It is easier to clean during use and reduces the trouble of maintenance.

However, enamel may also bring some negative effects. For example, some glazes may make the ceramic relatively fragile, not resistant to falling, and prone to chipping. In addition, the color of some glazes may fade over time, affecting the aesthetics of the mug.

The safety of the enamel component is also an important factor affecting the quality of the mug. High-quality enamel usually does not contain harmful substances and complies with relevant national safety standards, ensuring that users will not be exposed to harmful substances during drinking. Therefore, when purchasing a mug, you should pay attention to whether the product has passed food contact certification to ensure the safety of its enamel components.

When choosing a mug with good enamel, you can consider the following aspects:

1.Observe the appearance of the glaze.

A high-quality glaze should be smooth and clean, without obvious defects such as pinholes, slag or black spots. For medium-sized cups, pinhole defects, slag and black spots with a diameter of no more than 0.5mm should be as few as possible or even non-existent. Pay special attention to check whether the glaze on the inner and outer walls and bottom of the cup is uniform and flawless.

2.Check the physical and chemical properties.

Good enamel should have a certain degree of thermal shock resistance and not easily break when high and low temperatures alternate. In addition, water absorption is also an important indicator. For mugs made of high-temperature fine porcelain, the water absorption should be controlled below 0.5%. This can be tested by marking the unglazed area of ​​the sole with an oil-based pen and then trying to erase it. The ones that are easy to erase are usually fine porcelain, and vice versa are stoneware porcelain.

3.Consider color and decoration.

If the mug is colored glaze or decorated with decals, you should check whether the color is uniform, whether the decoration is complete, and whether there are no cracks. At the same time, pay attention to choosing a glaze with stable color and not easy to fade.

4.Listen to the sound.

Tap the mug gently. The sound of high-quality porcelain should be crisp and sweet, which usually means that the porcelain body is fine and the porcelain is completely transformed. If there are signs of hoarseness in the sound, it may indicate that the porcelain body is cracked or the porcelain is incomplete.

5.Choose a brand and reputation.

When purchasing, you can consider choosing a well-known brand or a manufacturer with a good reputation. They usually have strict control over product quality, and their enamel is relatively more secure.

6.Personal test.

If conditions permit, you can try filling liquids such as water or coffee to observe whether there is leakage and whether it feels comfortable during use.

The enamel of a mug plays an important role in the quality of the mug. It not only affects the appearance and use experience of the cup, but poor-quality enamel can also release toxins and endanger human health.
