Solders are not new alloys, since they were known in late Roman times when they were mentioned by Pliny. These solders differed very little from our modern ones. Tertiarium, consisting of one part of tin to two parts of lead, is known today as plumbers solder; and argentarium, consisting of equal parts of lend and tin, is still extensively used for many purposes.
