The article contains recommendations on empirical formula calculations. They concern methods of the determination of chemical composition of minerals (wet chemical methods and electron microprobe analysis), formula calculation procedures (anion- and cationbased calculations) and the presentation of calculation results. Examples of the calculations are provided and typical errors made when writing formulae are considered.
