Facility Forum - Fall 2016 - 17

when the moisture enters the granite there will also be some other impurities that will eventually stain the granite over the long term. Figures 3 and 4 show these granites in memorials that have been in the cemetery for many years. It is very obvious that the granite used for Figure 3 is premium granite that most families would choose for their memorial or, in the case of a cemetery, for their columbarium. Contrast for Sandblast Figure 2: Water absorption in different types of granite. It is located at the other end of the ChampsElisees from the Arc de Triomphe and in the neighbourhood of the Eiffel Tower. This monument was originally clad in Carrara white marble from Italy in 1989. Unfortunately the marble was too porous and is now falling off the building . French architects then began their search to find a perfect replacement for the marble and, following a year of visits and negotiations, selected Bethel white granite from the Rock of Ages quarries in Vermont. This project is the most prestigious job ever done in Bethel White, according to Robert J. Campo who is Vice President of Sales and Marketing for Quarry Operations at Rock of Ages. "We have the gold standard that all other white granites have to measure up to," he said. The new granite walls, he promised, "will stand up forever, not just 25 years." Granite Differences The mineral composition of granites will vary from one to the next. This variation in composition will provide the individual granites with unique characteristics. Some of the key differences include: Absorption Although granite is very hard, it is permeable. Rain or fluids will penetrate into granite. That is why most granite countertops being installed today are treated with a sealer. Sealers are not applied to outdoor projects as the UV rays will break down the sealer in a short period of time. Some granite will absorb more moisture than others as shown in Figure 2. The memorial shown in the foreground on the left hand side of Figure 2 is Barre grey granite from Vermont. The other granites, which have moisture rings on them, are from Georgia. Unfortunately Granite columbaria will normally have the shutters, also known as niche plates, lettered by a sandblast method. It is important for the families that the lettering be as legible as possible. Normally a dark granite will provide the best legibility. Sometimes, however, the background below the polished surface is also very dark and dull which does not provide a good contrast. A grey granite with a narrow deep sandblast line will also be effective and provide a more legible letter than some dark granites. The other important factor for an attractive sandblast letter or design is to have fine-grained granite. When the grain is large, the edge of the sandblast lines is jagged and rough. Surface Fractures Certain granites will have a series of hairline fractures in the surface. These fractures normally do not lead to any long term structural issues. They are, however, not very attractive and over time may collect impurities that will reduce the overall appearance of the granite surface. Pitting All granites contain some very small pit holes in them. Some granite will have more than others. You will need to look closely at the granite in natural sunlight to see them. The granites that are heavily pitted are normally used in construction and should not be used in columbaria or memorials. Polishing Luster Figures 3 and 4: Examples of water absorption in different types of granite over time. Certain granites will take a higher luster of polish than other granites. This normally is a result of the concentration of quartz. The higher level of quartz will provide a better luster. FACILITY FORUM | 17
