Silvering Glass to Make a Glass Mirror

Although earlier techniques of making reflecting glass mirrors had existed, it was in the period between 1200 and 1400 that chemical and alchemical experiments provided a satisfactory method to make high quality mirrors. Here Graham Reed of Scotia Glass Technology demonstrates the making of a convex mirror, from the original 'seeding' of the liquid, the setting of the sliver in the glass, to the final effective convex mirror.
