Tombstones are meant to highlight the final resting place of the dearly departed. These stone monuments have existed since well before the Egyptian times and in all likelihood, they were some of the first ways in which mankind memorialised those who had passed.
Modern headstones are designed to last for centuries; even when enduring extremely harsh weather conditions. This brings up an important question.
How are these stones able to withstand years of weathering? Let us take a look at the science behind headstones in order to shed some light on the subject.
The Principle of Hardness
Every type of stone is associated with its own set of unique characteristics. Slate can be cleaved along a horizontal plane.
Sandstone is quite porous and easy to manipulate. Soapstone can be used to make bowls and cups due to the fact that it is very malleable.
This is why those who design tombstones will always prefer to work with a material that is very hard. Most modern headstones are made from granite.
This igneous rock exhibits two important qualities. First (and most importantly), it is capable of withstanding the elements for hundreds of years if cared for properly.
Secondly, it can still be cut, polished and fashioned to meet the needs of the family in question. This is why ornate elements such as headstone inscriptions and etched designs can be carved with extreme detail. The rock itself is not likely to crack or chip.
Still, they may require sealant from time to time in order to preserve their outer beauty.
