Warren's grave stone is carved from Marble marble and is in fairly good condition. Applying Rahn’s Index for Weathering  weathering  the Grave grave stone is slightly weathered.  Marble being a ingenious rock and it stands well against mother nature much better then sand stone or slate. There are multiple large chunks of various rocks (impurities) and veins that are incased by marble suggesting it being a sandstone.  When touching grave stone tiny granular particle particles rubbed off easily indicating sugaring.  The inscribing is well worn where the once crisp edges now are left rounded by rain. Rain and moisture takes the largest role in the deterioration of the grave stone. No measures have taken to preserve or restore the grave stone and if there is nothing done spalling will become more severe and  fractures will increase. A portion of the stone may topple over like many others grave stones in the surrounding area that are constructed with simalar materials and fashion. 

This grave stone was of particular interest because off the teal oxidation happening on the bottom portion of the grave stone.  The entire grave stone appears the composed to three separate stones attached with a singular piece of unknown metal. The metal could be steel, iron, copper or other materials, but it can be concluded that copper is present because the teal coloring, (copper carbonate) on  the the stone.  When looking to other grave stones in the local area  there are several others with the same type of oxidation happening. The grave stone next to Louis Warren  was missing the upper potion and in the the center of the base there is a metal rod.

• Ferrous Pinning- Metal that rusts and expands was use extensively in historic monumental installations. It has contributed to a host of problems, including, cracking, staining, stone degradation, and complete collapse in some instances
