It is a well-known fact that marble is a highly appreciated material, which has a multitude of uses in various fields. Since ancient times, it was used in both construction and art, which is why nowadays we can admire statues and ancient temples made of marble and limestone. At the same time, it is a versatile material and is present in the field of construction and today, from museums to theaters, churches and personal homes.
We might think we know all about this natural stone, but some information may be surprising. In the following article, we will present you with 5 things you probably didn’t know about marble.
1. Oftentimes, it is confused with limestone
Limestone and marble are very similar in composition, both are basically calcium carbonate. However, they form through different processes. While limestone is a sedimentary rock, marble is a metamorphic rock. Marble is formed when limestone is subjected to extremely high temperatures and very high pressure in the Earth’s crust, causing a change in its molecular structure. The resulting rock is different in appearance and structure although it is, generally, regarded as a variety of limestone.
2. It varies in color depending on the intrusions
Although white marble can give any building a classic, elegant appearance, this natural stone can be found in a rich variety of colors of undeniable beauty. The most common colors that marble can have, besides white, are gray, black and red. These variations in color are due to intrusions such as iron salts (red), manganese (brown), or graphite (gray). At the same time, due to the formation process, these intrusions often form complex patterns on the surface of the marble.
3. The Greek marble statues were, initially, not white
When we look at some of the most appreciated works of art in ancient times, the Greek statues, it is difficult to imagine that they ever looked any different. Although their monochrome appearance is appreciated throughout the world and many assumptions have been made about the reasons why the Greeks chose white, modern technology shows us that, originally, they looked completely different. After analyzing the Greek sculptures with ultraviolet light, experts discovered that they were, initially, painted in vivid colors. Therefore, despite the simple and elegant appearance of white marble, it seems that the ancient Greeks’ intentions regarding these statues were different from what we can see today.
4. The Great Pyramids of Giza were, initially, white
Although the Egyptian pyramids are some of the most well-known ancient constructions in the world. However, very few know that what we see today is different from their original appearance. Thousands of years ago, the great pyramids were white in color, because of the limestone tiles that used to cover their exterior walls. The smaller pyramids were covered with similar, darker plates. They were removed later, in the period of the caliphate, and used in the construction of mosques. Therefore, what we see today is not the original appearance of these magnificent ancient buildings, but their internal structure, made out of stone blocks.
5. It is continuously changing
Even after processing, finishing and assembly, marble never ceases to be prone to change. To maintain its quality, maintenance is a very important aspect that will help preserve the initial shine and prevent deterioration of the surfaces over time. To prevent changes in appearance and quality, it is important to clean any marble surface often, with mild detergents, to avoid unwanted reactions.
