...reading through my last post, and thought I should explain that the introduction of soda lime and similar advances to help clear glass generally allowed the use of silica once again, rather than powdered flint. Silica (sand) was obviously much cheaper than powdered flint.
Actually you go through glass history and it goes round in cycles, different materials being used, dropped and re-discovered and re-used in different ways throughout the centuries, so it gets difficult talking about evolutionary developments!!!
