Guest guest Posted March 10, 2012 Report Share Posted March 10, 2012 hello Balsam,1) Zn act as scavvenger, but it also causes delayed expansion , so now many amalgam are avilable which are Zn free.2) silver and copper both contribute for the strength so its a bit tricky ! I think we talk in in general we decide the strength of amalgam on the basis of Cu content ! so mebbe here they want to hear Cu from us with this respect !3) and 4) I am not sure but Cu , Tn , Ag all can cause black staining and discolouration.Anyone has any opinion on this?RegardsDivi From: Balsam_Majid <balsam_majid@...> Sent: Saturday, 10 March 2012 12:13 PM Subject: Amalgam Ore questions 1- what component of amalgam was formerly used as a scavenger but is no longer widely used? 2- strength of amalgam depends on? 3- black stain of amalgam tattoo is caused by? 4- what component causes tooth blackening?
