The present invention relates to a very high performance refractory article especially resistant to corrosion, and to a new process for the manufacture of such an article. In particular, the invention relates to an article made of crystalline silica having high density and capable of withstanding the corrosive atmosphere of a glassmaking furnace, notably an oxy-fuel fired furnace. This article includes at least 50% by weight of crystalline silica, not more than 1% by weight of residual quartz and not more than 0.4% by weight of titanium oxide, having an apparent density greater than or equal to 1.88 and a flux factor less than or equal to 0.75.
