      Prices only indicative as actual quotations strongly depend on quality (grain size distribution, iron content, and overall impurities), volumes, transportation costs (quarry‐to‐plant distance and transportation mode) and, of course, market‐price fluctuations. RO = CaO and MgO; R₂O = Na₂O + K₂O.
