How do you melt marble?

Answer 1

Short answer, you can't. That is, unless you have a glass furnace. Marbles are made of several colors of glass that are melted together and made by a glassmaker. The heat that you have available at home simply won't do it. It takes heat of 2,000 degrees or more.

Here's a neat thing to do with marbles at home if your parents will help. Get a heavy iron skillet and heat it on the stove on high heat for 10 minutes. Put the marbles in it and let them heat along with the skillet. At the end of the ten minutes put the marble in water. It will steam and crack on the inside. This is called fried marbles and it looks really cool as jewelry. Be sure to have your parent's permission, and use safety precautions handling the skillet and the stove.

The interesting thing is that the marble doesn't melt, it cracks on the inside because of the trapped air bubbles that it got when it was made. You can't play marbles with it any more because the cracking on the inside makes the marble more fragile. It will shatter with force.

Answer 2

marble is a form of calcium carbonate and contains imprities that give it its aesthetcally pleasing appearance. In nature marble is formed by the melting of sedimentary calcium carbonate under high pressure and high temperature conditions. Melting calcium carbonate is very difficult under normal conditions, as it decomposes to from CO2 and CaO. As the decomposition reaction is reversible it is possible that a sample of finely divided marble heated under high pressure CO2 to will prevent decomposition will melt.

Answer 3

Marble is a type of metamorphic rock that cannot be melted down like metals because it will degrade under high temperatures. Attempting to melt marble will result in its decomposition rather than achieving a liquid state.
