A random interface of growing crystal is experimentally studied in a two dimensional system. The crystal grows from an NH4Cl solution and is polycrystalline, composed of many grains. The interface is rough and self-affine fractal. The roughness exponent is in the range of 0.79-0.91, where the average value is nearly 0.83.
