if marble forms from presure and heat undergroud in the ocean, how do you remove it?

You mine it.  Marble is found in many places.  It does not have to be mined from under the ocean.  It may have formed under an ocean many millennia ago, but much of the earth which was underwater then is now not.

dilute hydrochloric acid reacts with the carbonate component of the limestone and the marble, and a few drops on the surface of the rock will 'fizz' allowing identification  (non carboniferous rocks such as granite will not give any reaction) . I dont know the exact chemical reaction, but I think hyrogen or maybe carbon dioxide is given off, hence the fizz ( gas bubbles)

The evaporation from the ocean makes hot air.  Hot air moves creating charges.

Was the glass heatproof or pyrex? Probably the rapid heating caused the problem, not the salt water directly.

You will find most at stone shows which are held all around the world.  Verona, Italy, Miami and Las Vegas being some bigger ones.  Look at the shows website as well, you will find links to the companies directly.  Stone Expo is one of them.\n\nAnd if you want to antique a small amount of marble, try this, a cement mixer, puncture nails through it so the pointy part of the nails are exposed inside, fill with sand and marble and let it turn for 24 hrs to 7 days. The action will simulate the look of old marble.

Evaporation from the sea. Dig shallow pools and with bis leaves collect the moist. You can also get salt this way. Also collect the water from the rain.

crush it and put it in water

The chemical formula is CaCO3 (calcium carbonate). \n\nThey probably wouldn't make toothpaste out of it if it had dangerous amounts of arsenic in it. However, the content does vary, since limestone forms in the ocean it will have concentrations of many elements that are found in seawater.  For example in some Florida limestone the concentration of arsenic is 3mg/kg (3 ppm).\n\nMarble is a metamophosed limestone (not a conglomerate). Often in construction trades, polished limestone is called marble, although to a geologist it is still not marble. \n\nIn some water treatment plants  limestone (thus marble) is used to REMOVE arsenic from water. \nhttp://water.usgs.gov/wrri/02grants/2002SD1B.html\n\nI would say if you don't have to put it in your aquarium don't do it. The far bigger problem than the arsenic might be that if your aquarium is slightly acidic it will begin to dissolve the marble, and make the water rather hard. I can't imagine this would be good for most freshwater fish.

warm salt water to clean, then leave to dry out.

Sandstone will never become marble, sandstone metamorphizes into quartzite. Marble begins as limestone which is then altered by heat and pressure. As with most geologic processes, the time is variable depending on conditions.

Take a glass of wine before taking sea food.That will solve the problem.

'cause the water course, coming down towards the sea, removes small mineral amount that then deposits on ocean's founds.

The simple way is to make a solor still. Dig a hole, fill with some salt water.  Take some plastic (big enough to cover hole) Weigh it down around the edges so that it wouldn't move or blow away leave a hint of slack in it.  Put a smal rock in the middle.  Put a can/cup ect under the rock. As the water evaporates it will collect on the plastic, on drip from where the rock is.  Drips fall in cup.  Fresh water.  You can boil sea water and cool steam, collect drips in bucket.

Put it under a vacuum.

I know of two ways.\n1. It is mined from deposites underground.  They used to do this near where I grew up as the chlorine in the salt was used in the processes at the nearby chemical plants.\n\n2.  It is evaporated from ocean water.  Once the water is evaporated mostly what's left is just regular salt.  It just has to be cleaned up a bit.

The best way would be to collect the condensation from boiled ocean water. A moderate expense.

The mineral granite is not affected by acetone (which is nail polish remover). Nail polish can be used to seal the mineral from corrosive influences in air or water, but there are better skinning agents.
