Is your gilded porcelain real gold? Come and see how to identify it

When some friends go to buy porcelain, they often hear the seller say that this porcelain is painted with gold, and it is made of pure gold. The materials are very precious, so the price is also unusual. Hearing this, you must think 'Wow, pure gold, it must be very valuable, and it must be very stylish when placed at homeBefore bone china manufacturers give you some advice, let's first understand what the gold drawing process is. Trace gold is a decorative technique for chinaware ceramic, which refers to the use of principal gold or bright gold to make decorative patterns on the surface of the porcelain, and then enter the kiln for a second time and fire it at a low temperature to make the porcelain white porcelin dinnerware more precious and delicate. Why are gilded porcelains more expensive? On the one hand, the materials used for tracing gold are expensive, and on the other hand, the process requirements are relatively high. In the beginning, the color materials used for drawing gold were all gold powder, which was to make gold powder and add a proper amount of colloid to use, which was expensive. Later, the appearance of gold water replaced the position of gold powder. Compared with gold powder, gold water can be painted directly on porcelain white porcelin dinnerware with a brush. Reduce the cost of porcelain making, but also expand the scope of development of gold tracery technology. The white and shiny bone china cup with pure gold ornamentation is magnificent and luxurious. is a gift set of noble objects with artistic flavor. With the embellishment of gold, I don't know how many steps have been made to the identity level. However, due to the increase in material costs and changes in the market environment of modern porcelain, few people use pure gold to complete gold tracing. So how do we identify when we buy porcelain with gilded gold? 1. The color can be distinguished by the naked eye, the true golden color is pure and full, while the chemical golden color is more yellow and very bright. 2. Under a magnifying glass, it can be seen that the graininess of pure gold is strong and uneven, with a three-dimensional effect. The graininess of chemical gold is small and uniform. Under the irradiation of 45 degrees light, pure gold has very strong reflectivity. Jin Ze has a strong sense of fog. 3. Use 30% nitric acid to test on the gold surface of the porcelain. If it is chemical gold, it will fade quickly, while pure gold will not change. This method is the most intuitive and accurate method, and it will not damage the porcelain.
