tungstates

True, in the august presence of rhombohedral crystals, retinasphaltic resins, gehlenites, Fassaites, molybdenites, tungstates of manganese, and titanite of zirconium, why, the most facile of tongues may make a slip now and then.

~ -- The decomposition and solution of natural tungstates is difficult to effect owing to the separation of tungstic acid; the method of treatment is as follows: -- Boil the finely-powdered substance with hydrochloric acid or aqua regia till it apparently ceases to be attacked; dilute, filter, and wash with dilute hydrochloric acid.
