摘要：

Chemical gardens are the plant-like structures formed upon placing together a soluble metal salt, often in the form of a seed crystal, and an aqueous solution of one of many anions, often sodium silicate. We have observed the development of chemical gardens with Mach-Zehnder interferometry. We show that a combination of forced convection from osmosis and free convection from buoyancy, together with chemical reaction, is responsible for their morphogenesis. © 2002 Elsevier Science (USA).
