This metal is found oxidised in several minerals and occurs occasionally in the metallic form, in the slag of iron works, as small cubical crystals, exactly similar to copper in appearance, of Sp. G. 63, and very infusible. When heated with nitre, they are oxidised, producing titanic acid.

A more direct method was to evaporate common salt two or three times with nitric acid (esprit de nitre), when cubic nitre (nitre quadrangulaire sodium nitrate) was formed. This was deflagrated with charcoal in a crucible and the alkali extracted from the residue with water ... 

I took four drachms (gros) of vitriolated tartar reduced to a fine powder, mixed it with three drachma of very pure fuming spirit of nitre. A considerable effervescence was at once excited, accompanied by heat and very red vapours of nitrous acid. The mixture became pasty. I diluted it with a sufficient quantity of water to dissolve the saline mass and 1 set the liquid to crystallise. The salt which 1 obtained proved to be very piire nitre, crystallised partly in needles and partly in small cubic crystals.
