Spot testing

From: Karin Abelskamp <*k.abelskamp<-a*> Date: Friday, October 21, 2005 · k.abelskamp<-a

I am looking for a spot test to demonstrate the presence of tin in
an archaeological object made of a copper alloy object or a lead
alloy. Does anyone know if such a test is commercially available? If
so, where can I purchase it, preferably in the Netherlands?
Furthermore, is such a test perhaps also available for zinc?
