"The Revigator was intended to add radioactivity (radon) to drinking water. Water without radioactivity was 'devoid of its life element.'
The glazed ceramic body of the jar has a porous lining that incorporated uranium ore. Water placed inside the jar would absorb the radon released by decay of the radium in the ore.
Advertised as 'an original radium ore patented water crock,' it sold in the hundreds of thousands between 1924 and 1930."
