Bird's nest is a luxury tonic that we often mention. It is said that top-quality bird's nests are extremely rare and very expensive, but even ordinary bird's nests are mixed with fakes. The price of bird's nest is extremely high. When we buy fake bird's nest, we may feel worse than eating a lot of dead flies. However, as long as you know the most obvious difference between real and fake bird's nests, the possibility of you buying fake bird's nests is extremely low. Water absorption: There is another thing that people often overlook. Bird's nests absorb water very well. Even if it contains 10% water, the surface feels dry and hard. Therefore, adding water is also one aspect of increasing the weight of the bird's nest. There is no absolutely dry bird's nest, only relatively dry one. 2. Clear texture and natural cracks The surface of pure natural bird's nest is silky and arranged in layers. The hairy bird's nest, which was originally tightly connected by bird's nest fibers, will have a small amount of cracks after being picked out and air-dried and shaped. The number and size of cracks are related to the hair content of the bird's nest and also to the shaping process. The texture of the bird's nest that has been brushed with glue or applied with paste is very unclear. It can be made seamless by brushing glue on the inside or applying paste on the outside. 3. Fluffy and natural base The base of the raw bird's nest contains the most hair, so it must be cut open and picked out, which is very difficult to do and also causes the greatest loss. Some workers will pick out the base and stick it back, which is a reasonable way to reduce natural loss. However, most bird's nests on the market are covered with thick and solid grass bird's nest fragments, which are neatly pressed together. The base of pure bird's nest is fluffy bird's nest silk. Although it is ugly, it is ugly in a natural and pure way. The bird's nest supplemented with grass bird's nest fragments has a significantly different color from the base and body of the nest. 4. Colors are different The bird's nest in the rainy season is white with little color difference, while the bird's nest in the dry season is yellowish or gray; there is a difference in color between new bird's nest and old bird's nest, and the old bird's nest is darker; the forest bird's nest is relatively whiter than the island bird's nest; the color varies depending on the internal environment of the bird's house; the color of the bird's horn is usually darker than the nest body; the bird's nest with high water content is whiter than the fully dried bird's nest; the dry bird's nest has a good gloss; 5. There are impurities and fluff A skilled worker must pick 7-8 bird's nests every day, picking them roughly, carefully, re-inspecting and carefully selecting, and probably pick out tens of thousands of fine hairs every day. The small hairs adhering to the seams of bird's nest, or some individual impurities (small black spots) buried more hiddenly, cannot be completely removed. No matter how skilled a worker is, her time is limited, her energy is limited, and her ability is even more limited, so anything done by hand can never be 100% clean. |
