A method of depositing a carbon-containing substance in the pores of a porous body comprises establishing an open varying magnetic field flux loop and placing the body such that a magnetic field flux generated by the open magnetic field flux loop passes through a region of said body and heats that region, creating a thermal gradient across the body and bringing a thermally decomposable carbon-containing gas into contact with the heated region, thereby depositing a carbon-containing substance in the pores of said heated region.
