To Obtain Fluoric Acid
The anhydrous acid is made by distilling powdered fluor-spar with twice its weight of oil of vitriol in a leaden, or better, a silver alembic, the pipe of which fits into a bottle of the same material, surrounded with ice.. But as it is ⚫ usually required in a diluted state, water equal in weight to the spar may be put into the receiver. Great care must be taken, as the acid, both in its gaseous and liquid form, is very destructive. :
