The generations of the builders of the Taj are still working on soft marble called soap stone to hand carve sculpture, decoratives, ornamentals etc. The craftsmen of Agra have perfected a unique art form called Under Cut Stone Sculpture Here, a piece of stone is hand carved into a perforated figure and from the perforations inner portion of the scuplture is chipped out, bit by bit. The sculptures, made from one piece of stone, has no joints and practically hollow. The outer surface of the sculpture is covered with beautiful, intricate interlaced lines, geometrical figures - angular, curviform and flowing patterns. This art form is confined to Agra and has not reached any other part of India.
Soap stone has smooth texture, soft lustre and of numerous colours and shades.
Hardly two soap stone pieces are identical making these stonecrafts memorable and attractive gifts.
