PURPOSE:To provide a product matching natural environment by a method wherein a natural stone, e.g. lava, is heated and softened to an extent that it is not vitrified and after the natural stone is formed in an arbitrary shape, it is restored to a rockform state to combine a concrete product. CONSTITUTION:A natural stone, e.g. lava, burnt sand, a natural rock, is heated and softened to an extent that it is not vitrified, and poured in forms 2. Lava 1 formed in an arbitrary shape in the forms 2 is placed in a concrete forms 2, and concrete 5 is placed and the lava is formed integrally with a concrete product.
