　　其次是使用玻璃纤维布、纱布、树脂等其一或多种材料加固石膏成品。还有一种方法就是有时候乳白胶也是石膏制作的一大重要辅料。添加了乳白胶的石膏，成品将会比一般石膏要更为光滑细腻，但是在上色时油料会浮在物体表面，而不会被石膏吸收，因而要多加注意！

　　Next is the use of glass fiber cloth, gauze, resin and one or more of its materials to reinforce gypsum products. Another way is that sometimes latex is also an important excipient for gypsum production. The finished product will be smoother and more delicate than ordinary gypsum with the addition of latex white gum, but the oil will float on the surface of the object when coloring, and will not be absorbed by gypsum. Therefore, more attention should be paid to it.
