Artistically, gold-ruby glass (cranberry glass), present in the Roman Lycurgus cup and later in many church stained glass windows, owes its striking red color and optical properties to gold nanoparticles created when a gold precursor is added to molten silicate glass.141 Cosmetically, to blacken hair, the Greco-Roman practice of mixing of lead oxide and slaked lime with water created lead sulfite nanocrystals (5 nm), which accumulated in the hair cuticle and cortex.417 Martially, 17th century Damascus steel sword blades owed their high-quality mechanical properties to carbon nanotubes (CNTs) and cementite (Fe3C) nanowires found within their structure.326 Medicinally, specially prepared, “Swarna bhasma,” nanosized colloidal gold, has been used as an antirheumatic, antiasthmatic, and antidiabetic in Indian Ayurvedic practice for centuries.39 Application of the nanosilver colloidal formation “Collargol” as an antiseptic was reported in 1897.110
