　　Gluing method

　　The bottom surface of the 4-leg bracket is made wide. Increase the contact area and then use marble glue for bonding. Generally, glass countertops are used more. If the marble surface is processed, the bottom surface needs to be treated. Adding a layer of board (wood material) has poor overall load-bearing performance.
