Making Sodium Metal - This is one way sodium metal can be synthesized using NaOH and Mg. Mg, being a more reactive chemical than sodium at high temperature with oxygen, breaks down the NaOH, leaving ingots of elemental sodium within the ash.
2Mg + 2NaOH = 2MgO + 2Na + H2
Thanks to NurdRage for the equation.
