Identification method of shellac

1, color: the color of the glue is transparent, without black blood stains, which is very good and has strong expansibility. Yellow gum is commonly used, which is thick, light yellow, bright in color and excellent in swelling.

2. Size and thickness: The bigger and thicker the glue, the better the quality; After the expansion, the car body is large and the price is high. But some small fish have thin stomachs, low prices, good flower glue, flat and complete shapes and neat edges. Although some pieces are neither too small nor too thick, they are easy to clip, airtight and of poor quality.

3, dry tide: the more dry the glue, the better. For light, it should be transparent, clean in texture, without blood tendons and other things, bright in color, and dull in wet fish belly, which is inferior. Some glue centers are not completely dry, and all around are transparent, but the center is jade white. This kind of glue is called "flower heart glue" and its quality is poor.
