First, let me thank Harte for both pointing to a broken bit of stone working and attempting to educate me on some of the methods used by the ancient
Egyptians. I do appreciate that. I also greatly appreciate the free source material covering the topic. I haven’t read it in its entirety yet,
but I will surely do so when I have the time.
Now, as for Dolour’s responses (forgive me for not using the quotation feature, I’m still very much new to these forums and their tags)…
First, I would not call a schist “layered.” More precisely, a schist is foliated, which actually indicates a layering of plate-like mineral
species into distinct bands… And these layers of minerals do not have to be flat, and are often folded.
As for the level of differentiation of magma to produce granites, I must disagree. I just got back from a trip to Southern Ontario (academic, of
course…) where we routinely saw large masses of granite of consistent mineral species and layering (I'm going to show you some of the samples I've
collected). In fact, you’re more likely to see a difference in grain sizes from contact with a colder host rock (a chill zone) than you would see
anything distinctly different elsewhere, if the rock is simply a body of granite. And I will remind you; the granite does not necessarily need to be
injected into cold host rock, and thus does not need to show much of a chill zone. Igneous bodies can be very massive and very consistent (for the
most part). Not just small chunks, large masses, road cuts of exposed granite a story or higher, spanning some kilometers where not uncommon. That
said, I am indeed unfamiliar with the granites found in Egypt, but would expect to see something similar… There are only so many ways to produce
I will post some pictures of my rocks and again mention that these “coincidental features” of twinning and mineral cleavage are actually inherent
properties of the rock… I apologize in advance for the terrible lighting and picture quality… Phones are not supposed to be cameras…
Hopefully these images aren't too large...
Notice the nice angles I got from merely smashing the rocks in an attempt to not have to carry giant blocks of granite. Notice the luster of the flat
twinning surfaces, which you will note that the Amazonite is bound by two such surfaces… Notice that getting a flat piece of granite might be
easier than you think.
As for expertise in machining, I grant you that. I have none, and I will take you word that the work is worthy of
admiration and wonder.
As for the sarcophagus, not every painter can be Rembrandt. Not every physicist can be Einstein. Sometimes there are just people who excel at what
they do, before a time when they should be able to do it… They outshine their peers as well as (sometimes) the generations that come after. No
offense, but these people might have spent their entire lives, their entire childhoods, learning how to do that kind of work. We go to school, get
balanced educations, or just have fun.
As for the sample I created, tiny. I was making it as a gift and didn’t want the recipient to have to carry a large chunk of rock.
Now do allow me to say thank you for educating me, as well, Dolour. I’ve gained a deeper appreciation of what the ancient Egyptians must have gone
through to create those huge blocks. In searching for answers, I found this wikipedia page... It shows some unfinished granite blocks about midway
down the page.
A rock hound.
