I am endlessly fascinated by what can be done with olive oil. The gorgeous Gothic Cathedral of York Minster has undergone a lot of damage to its stone work. The acidic pollution in the atmosphere has eroded and pitted the limestone and no protective coating seemed to do the trick, until …
Preservationists tried olive oil. The oleic acid in olive oil binds to the limestone and also repels moisture. The olive oil has been mixed with a Teflon-like material to provide further protection. The new marinade is currently being tested to see if it can be used for the entire structure.
If it works then I suggest the EU unload all the stored olive oil on preservation projects throughout Europe. What a win-win.
