Ed. note: Commercial patinas for pewter are available, Peter ⇨

A. Try 20%iron (III) chloride solution (objects must be grease and oxide free!). At internet archive you can download/free!/ very good old book on metals colouring by Arthur Hiorns; there you can find small chapter on colouring of tin and pewter. Hope it helps and good luck!
