    How does a block of marble compare to glass marble.
    The block marble is use for counter tops.
    Glass marbles is like the marbles we played with as kids.
    I want to know if the counter top marble is an
    insulator or conductor. explain

    Google answered my question,
    thanks anyway

    Is this a real question,
    or are we reading your poem entitled "Question".

    If it's a poem,
    I like it.

    If it's a question,
    the answer is, insulator
    because the typical constituents of marble,
    dispite the wide variation of constituents
    from sample to sample,
    have conductivity in the range
    we normally classify as insulator.

    I hope you liked my poem entitled "Answer"

    Dialog- If I stand on slab of marble and touch
    the Loosewire I will be shocked, that makes it
    a conductor not an Insulator.What if you could
    afford marble floors.Wikipedia mentions rock and
    stone when they are describing marble,real
    marble.
    What got me started on this was the first a/c

    unit being a block of marble that was put out

    in the cold desert night,and back in building

    during the day for cooling. Absorbing heat got

    me thinking about conducting in the heat exchange.

    Any dialog.

    Isn't marble a constituent of different types of rock, so I don't think there can be one blanket statement about the insulation or conductance, I would figure it varies with the sample.

    If I stood on a marble a floor bare footed I would get shocked.
    Just about any type marble would be ground.

    Glass marble, glass is made of sand thats a form of ground.

    Yep,lost my marbles.That what I get for thinking about
    cool things.

    A glass marble is Silicon Dioxide, it can melt, but it won't burn.

    Marble is Calcium Carbonate, which is pretty active chemically. Then you take a Tums you are eating processed ground calcium carbonate. Really.

    Heat marble enough, it will burn, just like coal.

    There a college education on glass making on wikipedea.

    The a/c properties of marble relate to its heat capacity more than its thermal conductivity. There is a relation between them, but it's not a hard relationship. Thermal and electrical conductivity correlate to a greater extent. The range from conductor to insulator is a broad spectrum extending over something like 40 orders of magnitude.

    Something like marble is more in the middle, but leans towards the side of insulators. For, example, it's within 1 or 2 orders of magnitude from deionized water, which is considered an insulator. It's also not too far off from pure silicon which is considered a semiconductor that (when undoped) is not a very good conductor of electricity.

    Silicon dioxide (glass) is usually considered a very good insulator. I've handled pure silicon due to my job, while it looks like glass it isn't really.
