One of the major projects here is the production of potassium sulphate, commonly used in fertiliser.

Examples of substances crystallizing in this class are extremely numerous; amongst minerals are sulphur, stibnite, cerussite, chrysoberyl, topaz, olivine, nitre, barytes, columbite and many others; and amongst artificial products iodine, potassium permanganate, potassium sulphate, benzene, barium formate, &c.

Lithium potassium sulphate, strontium-antimonyl dextro-tartrate, and lead-antimonyl dextro-tartrate are examples of this type of symmetry.

The sal polychrestum Glaseri is normal potassium sulphate which he prepared and used medicinally.

The desired products are nitrogen and carbon dioxide as gases, and potassium sulphate and carbonate as solids.
