Why Is Marble Cold? (ANSWERED)

If you’re a rock enthusiast, then you might think that marble is pretty interesting. One question that many people have about this particular rock is why is marble cold?

Answer: marble conducts heat in a different way than other materials. Marble is very thick and compressed, making it easy for heat to escape the marble quickly.

Here is an overview of marble in general, including some other interesting facts about this popular stone.

What is Marble?

Marble is a rock that results when limestone has undergone metamorphosis during a special heat and pressure process.

Marble is comprised predominantly of calcite, which is a mineral, in addition to other minerals like quartz, pyrite, iron oxides, clay minerals, micas and graphite.

Once these minerals have undergone the metamorphosis process, the material becomes crystallized.

This crystallization is what gives marble its swirled, mosaic look, which many people consider very attractive.

There are many types of marble, depending on where it originates.

For instance, several types of marble originate in the United States.

The Yule marble, which is a pure white, originates near Marble, Colorado. Etowah Marble originates in Pickens County, Georgia and consists of pink, rose and salmon colors.

Another type of marble that also originates in Pickens County, Georgia is the Creole.

Creole marble is white with black and blue. 

Some other areas around the world where marble can be found are: Greece, Italy, Sweden, Romania, Turkey, Serbia, North Macedonia, Spain, Russia and India.

The marble in each area is unique and has its own combination of colors.

Many types of marble are white or pure white, but many people feel even white marble is beautiful because of its glossy and smooth appearance.

The color of marble is determined by the minerals that the marble consists of.

For instance, pure white marble is that color due to calcite, limonite produces green or yellow marble, and hematite produces red marble.

What is marble used for?

Marble is used in a number of ways, but the most common uses of this material are in sculpture and as a building material.

Sculptors began using white marble as the material of choice during classical times.

It was preferred because of its beauty and ease of use.

When marble is first excavated, it’s very soft and easy to manipulate, and therefore easier to carve. 

As the marble ages, it hardens and becomes dense.

Sculptors also appreciate the fact that marble is virtually shatter proof, and it is one of the few types of stone that is able to yield the “waxy” appearance that sculpture typically has. 

White marble continues to be the rock of choice for modern-day sculptors, for the exact reasons it was preferred centuries ago. 

The use of marble as a building material began in ancient Rome and Greece, where, in addition to being used to construct many small sculptures, it was also used to construct gigantic pillars, as well as floors, walls and ceilings in places of worship.

People during those times encountered significant challenges in mining marble, as it was a time-consuming task.

It required the use of wooden beams, pulleys, levers, and winches.

Fortunately, the process of extracting marble today is a great deal simpler and quicker, due to the modernization of mining equipment. 

Builders use marble during current times when constructing homes, churches, and more.

When used as a building material, marble is used when constructing countertops, walls, and even floors.

Many homeowners opt for marble for their countertops and tile in bathrooms because of its attractiveness.

Marble can also be used in homes to promote cooling, as it can act as a natural air conditioner.

Many centuries ago, marble was only present in the homes of those with wealth and power.

However, nowadays, marble is present in many homes, regardless of stature. 

Why is marble cold even when a room is warm?

The temperature of an object will depend on the direction in which heat flows.

For instance, if you walk barefooted on a marble floor in a room where the temperature is 72 degrees Fahrenheit, the floor will feel noticeably cooler than other areas in the room.

It may even cause you to feel noticeably chilled while you’re standing on the floor.

That is because marble is a conductor, and it causes heat to flow from your feet to the floor, resulting in you experiencing coolness. 

As you can see, marble is quite an interesting, historical, and versatile stone, and if you’re interested in studying or collecting this rock, you’re likely to thoroughly enjoy it.
