Ejiao is true when it is yellow as amber and light as black as paint. True people have no skin odor, and summer is not wet and soft. Fire test: put a little sample in the crucible and burn it, which will burst at first, then swell and melt, emit white smoke, and have a strong aroma of sesame oil. After ashing, the residue is dark black, loose, flaky or lumpy, and does not stick to the crucible; Water test: Boil and dissolve, the solution is light brownish red, turbid, and there is white material precipitation, and there are oil drops on the liquid surface. Take the glue and dissolve it in water, and the liquid is clear without turbidity; Clap: Clap the desktop hard with your hand. If the broken section is brown, translucent and free of foreign objects, it is true. If it is soft but not broken, it is suspected to be counterfeit.

The first fake product of Ejiao is Niu Pijiao, which is hard and not easy to break. It has a strong odor when burned, and there is no oil drop on the surface of the water test solution. The second is miscellaneous leather glue, which smells like soybean oil when burned, and the water test solution is dark gray-brown red with a few oil spots on the liquid surface; Third, bone glue, the surface is opaque and dull, with small holes caused by bubbles, irregular wrinkles on the side, hard and not easy to break, and slightly smelly; The fourth is gelatin, which is smooth and bright, crisp, slightly gassy or smelly like ink. After fire test, it turns into white flake powder, which is not bonded.

In addition, the donkey-hide gelatin solution does not agglutinate after standing for 4 hours, and the counterfeit solution coagulates into a paste.

In addition, the appearance of turtle glue and deer glue is similar to that of donkey-hide gelatin, which should also be identified: turtle glue, with brown and slightly green surface and yellow "oil head" on it, is as clean as amber and hard to light; Deer glue, with black-brown surface, translucent to light, yellow-white porous thin layer on one side, brittle and brittle, reddish-brown cross section and glassy luster.
