“To save a crumbling cathedral, Marinate in olive oil”

Source: Discovery

The York Minster cathedral is crumbling due to “acid rain”, reports Discovery.com.  Common kitchen ingredient, olive oil combined with a “teflon-like” material may be utilized to preserve the limestone structure.  Tests are underway.  Here’s more from the article:

“By combining the olive oil with a Teflon-like material, researchers hope to protect the porous limestone from acid rain, while also allowing the stone to breathe, according to Gizmag.com. (Acid rain forms from both natural sources, such as volcanoes and decomposing plants, and man-made sources, mainly the sulfur dioxide and nitrogen oxides from fossil fuel combustion.)”
