Emboss is a product of the combination of sculpture and painting. It uses compressed methods to process objects, and uses three factors such as perspective to express three-dimensional space, and only for one or two sides. The relief is generally attached to another plane, so it is used more on the building and is often seen on utensils. Due to its compact nature and small footprint, it is suitable for decoration in a variety of environments. In recent years, it has occupied an increasingly important position in the urban beautification environment. The relief is as colorful as the sculpture in its content, form and material. The embossed materials are stone, wood, ivory and metal. Ammonium Sulphate,Ammonia Sulfate,Ammonium Sulfuricum Sanji Chemical Trade Co., Ltd. , http://www.lysjchemical.com
