The method of procedure depends upon the amount in the substance under investigation and also upon the condition of the silica, whether in the form of sand, or as a soluble or an insoluble silicate. The determination is beset with difficulties, but these are by no means insurmountable. It has been the object of much careful study and investigation and very accurate results are attainable even by persons who have not had much experience in quantitative analysis.
