Sodium by electrolysis through glass

In his 1926 thesis Robert Cady Burts [describes the production of sodium by electrolysis of sodium nitrate through glass](http://thesis.library.caltech.edu/4369/1/Burt_rc_1926.pdf).


I can't find much else on this method. Are there any modern descriptions of the experiment? Videos maybe?




See Shakashiri's chemical demonstrations. He carefully outlines the steps. As I recall it requires taking sodium nitrate into a molten state and applying a current. The elemental sodium is precipitated on the inside surface of an incandescent bulb.
