Rubbing is a very ancient Chinese method of recording. At times I have used a rather different technique in order to bring out the nature of the particular stone, and to pick up every cut of the original carved monument. There are different ways, or combinations of ways, to do this, depending upon the type of stone, its moisture content, and the degree of humidity. A hard black basalt monument from Kaminaljuyu calls for a different technique than the more porous limestone of Tikal, the moisture laden bas-relief tablets at Palenque, or the lime encrusted overhead lintels of the doorways at Yaxchilan or Bonampak.
