New Type of Marble Protection Derived From Human Teeth and Bones
Researchers at Princeton University?s Department of Civil and Environmental Engineering have discovered that hydroxyapatite, the primary compound found in human teeth and bones, can be used to help preserve the condition of marble, which is prone to cracking and deteriorating as a result of the effects of pollution and the weather.

"Environmental temperature variations cause the opening of cracks inside marble, and rain causes dissolution of the carved surface."

Being composed of the mineral calcite, marble naturally reacts with a phosphate salt water solution to create the hydroxyapatite. The water enters and strengthens the stone by sealing cracks from within, without affecting its color or reflectivity.Hydroxyapatite is also non-toxic and easy to apply, adding to its advantages as a new sealant for marble. It also t...
