Purchase fish glue notes.

1, the larger the head of the fish glue, the heavier the weight of the glue, but also the thicker. Generally the price of fish glue is based on the size of the head to pricing, we say the number of fish glue, is calculated by the number of fish glue per catty. The bigger the head and the heavier the weight of the fish glue, the better the quality of the fish glue.

2, the quality of the old fish glue is better than the new fish glue, the color of the old fish glue is more yellow, look at the meat can be divided into dark yellow, golden yellow, etc., and no fishy smell. New fish glue color is lighter and slightly fishy.

3, the real fish glue is not the whole color or all white. Only translucent, with natural lines, uneven amber-colored fish glue is not bleached top quality. Nowadays, in order to pursue the beauty of the appearance of fish glue, many sellers use bleach to bleach the fish glue, in fact, this has destroyed the essence of the health of fish glue. I suggest to pick the original color, with natural texture and blood fish glue is really good fish glue.
