The invention relates to a preparation method of imitated jade glass. The preparation method for imitated jade glass comprises the following steps of: polishing the both surfaces of plate glass, crushing the plate glass into blocks with sizes of 70-100 mm, cleaning and stacking in a trough layer by layer, then uniformly scattering bauxite, andalusite and silicon carbide reaction aids on the crushed glass, then heating the trough to 730-780 DEG C in 15-17 hours, insulating heat for 32-38 hours and then cooling to a normal temperature in 18-22 hours to obtain the product. The product has light-transmitting and lightproof effects, is of jade texture and many colours, is free of radioactivity of natural stone, as also has higher acid-base resistance, corrosion resistance, impact resistance and compressive strength than natural stone; the crushed particles are not sharp, cannot injury people, has good machining performance, good ageing resistance, does not absorb water, capable of persistently keeping a bright colour, and simple in installation method. The product is widely used in decoration for the interior and exterior walls, floors and furniture of buildings such as whole curtain walls, high-grade residences and clubs, is far superior to natural stone in both visual sense and tactile sense, noble and elegant in decoration effect, and is a new generation of environment-friendly decoration materials.
