Zusammenfassung:	Method for manufacturing glass, comprising preparing a mixture of glass raw materials for a glassworks furnace, wherein water, sand and sodium carbonate are mixed in mass proportions of between 0 and 5%, 40 and 65%, and more than 0 and no more than 25% respectively, and, within a time of less than 10 minutes, preferably simultaneously, calcium oxide is added in a mass proportion of between 1 and 20% of the total, the calcium oxide has a granulometry such that more than 97% by mass does not pass through a sieve of 0.125 mm, more than 96% by mass does not pass through a sieve of 0.5 mm, preferably more than 95% by mass does not pass through a sieve of 1 mm.
