The zinc Is rapidly covered with a velvety grey coating, from which after a while shiny silver needles grow in a more or less horizontal direction. These build up into skeletal crystals, the lead tree. The spectacle of crystal growth is particularly attractive to the obser er when the room is partially darkened and the flask illuminated from the side by a strong light. The experiment takes about half an hoiir. ... 

A beautiful lead tree is formed much more quickly if ca. 100 mL of a 1.0 inol/L aqueous lead nitrate solution are electrolysed in a crystallising dish... 

The major alloy of tin recovered from archaeological sites is pewter. This can be divided into those containing lead and lead-free alloys. The former could have a lead content ranging from 67 % (equivalent to plumbers solder) down to 15%. The French in Elizabethan times kept the lead of their wine goblets to below 18% as above this, the wine would become tainted As the lead and tin are insoluble in one another, they are classed as a two-phase alloy and articles could only be manufactured by casting. The lead-tree pewter was invariably an alloy of tin with a small amount of copper (0.5-7% for pewter recovered from the Maty Rose). The copper dissolved in the tin crystal structure resulted in a single-phase structure, which was considerably harder than pure tin. Hence this class of pewter could be subjected to a limited amount of mechanical working to achieve the final shape. 

Lead Trees.—In a three pound glass jam jar, nearly filled with filtered soft or rain water, put one to two ounces of acetate of lead, previously well powdered, if necessary shake the mixture and allow it to stand imdisturbed for two or three days decant the clear fluid from the insoluble residue (if any), reject the latter, and, after having rinsed the jar with water, retium into it the clear solution next fit the top of jar with a bung or piece of wood from which can be suspended thin strips of zinc, so twisted and shaped as to resemble as much as possible the branches of trees. On no account shake the jar—stand it on one side for several hours, when a beautiful metallic tree-like growth will be found to have formed. 

The alchemists were fond of producing the silver tree or arbor Diana by suspending some suitable metal in a solution of a soluble silver salt such as lunar caustic (silver nitrate) in much the same way as the better known lead tree is grown (p. 194). It is very beautiful to watch under the microscope the growth of silver on a piece of metallic copper. ... 

A favourite experiment was the production of the lead tree or arbor Saturni by suspending a piece of zinc in a solution of some soluble lead salt such as the acetate, popularly known as sugar of lead . The experiment is popular to-day. 

A favourite experiment was the production of the tin tree by suspending a rod of zinc in a solution of tin chloride tin deposited as the zinc dissolved yielding the arbor Jovis, analogous to the silver and lead trees already mentioned.
