Barite is ground into a fine powder and dissolved in sulphuric acid containing free sulphur trioxide. The solution is then poured into water and then it gets a precipitate of barium sulphate. The precipitate is filtered and evaporated to get a crystalline substance, the barium sulphate or Blanc-fixe. A good cream-floated razili is about 99%.
