In China seals were used since at least the Shang dynasty. In the Western Zhou, sets of seal stamps were encased in blocks of type and used on clay moulds for casting bronzes. By the end of the 3rd century BC seals were also used for printing on pottery. In the Northern dynasties textual sources contain references to wooden seals with up to 120 characters.

The most important limitation of stone is the lack of tensile strength, the capacity of a material to withstand binding.
Stone is durable and impressive stuff, but it's also challenging to quarry, and heavy to move, and it has tension and stress limitations. Where there are resources available to excavate and cut it precisely, stone can be an extremely strong and useful natural material. Unlike brick, it can be stacked without mortar and support heavy vertical loads. Stone resists deforming, weathers the elements well, withstands fire and helps maintain stable interior environments.
