fire, cremation is the key to immortality! and cleanliness

I like extra cheese and pepperoni on my tombstone. Oh that kind of tombstone I like marble.

I would say the best material from which to make a tombstone is quartzite. This is a metamorphic rock that is made almost entirely of quartz. Quartz is about the most durable mineral there is under surface conditions. Additionally, water would have a very difficult time penetrating the surface of quartzite, harder than it would be for most other stones. So, its chemical stability and resistance to penetration would make quartzite about the best rock there is for any monument that you want to last. Of the types of stone from which one might make a tombstone, marble is probably the worst. Marble is made of the mineral calcite which is quite reactive. Over time, it dissolves fairly quickly, rendering inscriptions illegible. Finally, we must define what is meant by quickly. Under normal condition, it would take centuries for the differences in erosion rates to really become significant. However, if the air in the region is polluted enough the difference could become evident in decades. So, if I have a tombstone to mark my grave when I die, then this geologist would prefer it to be made of quartzite. (Personally, I think I favor cremation more. Once I am dead, I don't need this body anymore so recycle it and release its elements back into nature where they can contribute to the next generation of life.)

I like granite.

Some form of granite is what I would use.

Granite most likely.

Italian Marble.

Granite is an igneous rock composed primarily of quartz, feldspar, and plagioclase feldspar with other small bits of minerals mixed in. Granite can be white, pink, light gray, or dark gray. This rock is made from magma (molten material) that is slowly cooled. The cooled magma is unearthed through shifts in the earth's crust and erosion of soil. And is by far the best choice for a headstone as far as one that is resilience. Marble is a poor choice as it chips very easy and very hard to repair. As I work at a cemetery I see many headstone every day and how easy some of them can be damaged as we have to move them in the coarse of do business. Our cemetery dates back to 1905 and the granite ones are by far the headstones that are still in great shape still today. and I just went 2 weeks ago and ordered my own, a granite bench for a headstone.

rubidium???

Marble for sure.

Paremesian cheese. .....Wanna buy a tire?
