      Your comment made me curious if you had any good rock hounding, lapidary or other useful videos in your playlists. So I clicked on your thumbnail and and looked for myself. I've created my own playlist of your public playlists, I'll remove the black/white movies later, lol, since that's not my cup of tea. So thanks for your variety of rock hounding, lapidary and OTHER videos for me to explore. Great taste!

    A few corrections: 1) Your apatite is actually grossular from Lake Jaco, Mexico. 2) Bauxite is a rock, not a mineral. 3) Cinnabar is mercury sulfide, not oxide. 4) The second copper is natural, not a smelter product, from Michigan. 5) Your hematite ring is most likely a manmade material. 6) Malachite is copper carbonate, not oxide. 7) Quartz is not glass. 8) Your smoky quartz crystal is an irradiated crystal of formerly colourless quartz, from Arkansas.

      Glass and quartz are both SiO2, but glass doesn’t form the same hexagonal crystal structure because it cools much faster. Glass typically has other things added to it (such as potassium) to lower its melting point. So in a sense, quartz is glass, because they have the same chemical makeup.

      Hi, If you're on a coral atoll, there might be no minerals other than shells and coral. The rocks made entirely of shells are called coquina. Volcanic islands might have zeolites, which come in many varieties, and contain rare earth elements. Maybe olivine, which in large clear crystals is commonly known as peridote.

      Hi star, there are message boards and forums (I believe there is also a sub-forum on reddit) where you can share pictures and give exacting description to find the the most accurate identification. It is more difficult to identify when not in person but there is specific criteria for identification of any stone. Check out a gemstone or mineral forum and they can help guide you.

It's clear that you know waaaay more than I do about this kind of thing, and maybe it is ok to say that glass is quartz, but quartz is not glass (super simplified). I'm afraid you will have to dumb down your explanation to me because I am not well educated in this subject. Thanks for this video.

    Walking through the woods (in New York), I came across a large amount of very, very shiny, glasslike rocks. I picked one up, and hit it with another rock and it fractured very easily into a little shard. They are all deep black, and working with them leaves a black residue. I took some of it home with me. Any idea what it could be?

  • @blunosr

    Well, there's only so much you can say in an 8 minute video. Maybe one day I'll do a separate video for each mineral. There's a lot to know about each mineral. Someone else asked about uses of each mineral, and yes, most of these do have uses in industry, but again that would be a very long video.

  • @blunosr
    @blunosr  11 років тому +2

    Hi, I think you mean "glass". Yes, it is largely made of quartz sand, although in many cases, other minerals, or elements are added to give glass different properties. For instance, boron is added to make glass heat resistant (Pyrex glass). KMnO4 (chameleon mineral) is added to make purple glass. Addition of gold III oxide, makes red glass.

  • @tinker6670
    @tinker6670 6 років тому +2

    Just a suggestion.. on basic identification you should begin with a hardness test. This basic test will rule out what the material won't be and put it in a category more close to what it really is.

  • @matlynch83
    @matlynch83 11 років тому

    Glass is made from quartz grains (sand), heated until it melts and then cooled quickly. Because it is cooled quickly, it does not develop a fixed crystalline structure. However, quartz cools slowly to develop crystals that do have a crystalline structure. Natural concurrences are volcanic glass obsidian which is formed from felsic silica rich lava which cools quickly to form glass. If it cooled slower, it would form the mineral rhyolite.

    @coherantbliss3483 8 років тому +1

    Thanks for your vid. I have a question and don't know if you can answer it. Of which mineral/stone family gives off the most spark/energy when striking each other? And which one mostly absorbs energy? If you don't know what would be your guess? I have seen a video that if a certain stone is used with copper it can create energy.

    • @SoulDevoured
      @SoulDevoured 8 років тому +1

      I'm not entirely sure I understand all your questions but I do know that flint stone and steel (or any iron based metal/mineral) is what is used to make sparks and ignite fire. As far as stones that absorb energy, nonmetallic ceramic like stones, like talc in this video, are probably the best bet there. I believe asbestos is also very insulating but I wouldn't recommend it for any science experiment you're gonna try at home.
      Or if you mean absorb energy as in carry/conduct it, any common metal mineral will work. With zinc, gold, and copper being among the top.
      Sorry I can't help much more. I suggest searching google for "the least conductive minerals" or "conductive properties of common minerals" for a better shot at finding the MOST conductive and insulating minerals.

    Hi, I would guess that it is an igneous rock type called Gabbro. The black residue would just be the oxidation product from weathering. New York is in the Appalachian or Laurentian mountain chains and there are many mafic igneous rocks. Gabbro is kinda like granite, except black.

Their crystals are so small, they are hard to see even under high power, and you have to use cross polarization. I'll have to look into that...

    Hi, individual minerals are pure chemical compounds. So in that respect, yes they all have commercial value.

That's how we get many of the chemicals that you might see in a lab, or pharmacy.

    Can Gabbro be really glossy? I just took out a chunk of these rocks and cleaned it with water and an old tooth brush. In the process, I noticed that not all of the rocks have a black residue, and the ones that do have a very small, but visible grain. So do you think those would be gabbro? There are a few that have no grain to the naked eye, and they are really shiny and glossy. I'm thinking about trying to grind it into a marble or something, they look awesome.

    Hi, if what you mean by "points" is arrow heads, they were made of many things, most of which were bone, or rocks, not minerals. I suppose you could use quartz though. Good arrow heads can be made from obsidian, or chalcedony (chert/jasper). In fact obsidian is still used today for some scalpels in very fine surgery, like brain surgery. At least, that's what I'm told... Obsidian can be made sharper than steel.

Horses would freeze to death outside of our igloos.We eat many different types of Beaver and lots of it! In fact I'm eating one right now. I'm sure your just another lonely American trying to make friends by making up stupid shit. Kinda like saying there are many roadkill buyers in Canada that pack up the retarded diseased animals and ship them south cause Americans love their roadkill sausages...or highway caviar depending on what state your in. Maybe you should get yourself a beaver so you don't have so much time...or anything else on your hands.

    I found a rock whilst on the beach and I noticed it was shining. So I picked it up and there was a little hole and inside I could see some light orange shining crystal formations. On the outside the rock is mottled grey and quite smooth. Could you tell me what it is?

    can quarts be dark black and grow inside (on the side of) a clear shiny possible quarts rock? it isnt crystal shaped in anyway its either a chunk of a really large quarts crystal or a completely different mineral all together. the black crystal is fairly soft and can fragment if hit hard enough with a rock hammer, only small pieces but the clear rock crystal thing doesnt fragment, crack, even stress the slightest bit no matter how hard i tried to chip it with a chisel and rock hammer.. help?

    Okay, I tried to hardness test the rock. It can't scratch glass, my finger nail can't scratch it, but a 2007 penny can scratch it. So that would mean its hardness is between 2.5-3, right? Does this help narrow down what rock/mineral it could be? Very shiny, no apparent cleavage or foliation, dark black color, very shiny/glasslike, hardness

    Very cool. I really like the green and blue coloured rocks, imagine building a house with them! I wish the camera focused a bit better though, it did the video injustice.

    i've got a rock that is extremely magnetic but it has what looks to me alot of rusty golden color in slots in it and very shiny black and i was wondering if it would be the same as the one in this video and if not would you have an idea of what it could be. thanks

    Not to argue too fine a point, but Cinnabar is HgS, not HgO. Nice collection, as a geologist myself, I love my mineral collection and wish I had some cabinet samples as large as yours although with all the rocks and minerals I do have, I think I would have no place to sit. Cheers.
