Glass and Glass making is an extremely old technology, the history of which has often been recounted, but is constantly in need of revision as archaeological evidence keeps advancing our understanding of various aspects and throwing up new puzzles [1]. During the years of developments, the general advancement of science and the evolution of glass making (tailored glasses) have interacted with each other. Few events earlier the middle of the seventeenth century deserve detailed discussion, until that time chemistry and physics were too primitive to able to assist development of high temperature processes like glass or ceramic manufacture or iron making. But before proceeding it is salutary to remind ourselves of the brilliant technical achievements occasionally produced in distant ages.
