Cristallo is a glass that is totally clear (like rock crystal), without the slight yellow or greenish color originating from iron oxide impurities. This effect is achieved through small additions of manganese oxide.[1] Often Cristallo has a low lime content, which makes it prone to glass corrosion (otherwise known as glass disease).
The invention of Cristallo glass is attributed to Angelo Barovier around 1450.[2]
