Preparation of Vanadium by the Aluminothermic Process

Prepare 16 g of an incendiary mixture (see p. 202). Insert a magnesium ribbon into the hollow made with a test tube and spill the incendiary mixture into the hollow. Place the crucible into a bath with sand. Perform the experiment on the floor near a fume cupboard or in one. Carefully ignite the magnesium ribbon with a burning splinter inserted into a long glass tube. After the flash, let the molten substance cool, break it up, and extract the metal bead.
