The Master of the Rocks School seems to have specialized in carvings from this distinctive material. The School's main output was bottles carved with landscape designs, but many other subjects are recorded, including a few with chi dragon designs, which may have been partly produced for the Court. The quality of carving and the use of material of the present bottle are typical of this School.

Exstein Collection was sold at Christie’s New York, 21 March 2002, lot 158.
