Want to Know About Stones | Crystal Comprehensive Guide

It is plutonic rock and is generally called granite. It is the most commonly used stone for building stone. It is hard, resistant to weathering, has a specific gravity, and has excellent pressure resistance. High-quality products often have a low water absorption rate, so it can be said that they are most suitable for use as structures.

However, it is vulnerable to high temperatures and heat and may crack or break if exposed to burners or fire. The significant difference between stone and other structural materials is that rock is not a stable substance in which a single element or fixed content mixes at a specific rate.

Thermal Suspension Effects & Cracks

Granite is composed of various minerals such as mica, quartz, and feldspar, but their ratios and combinations are not always constant. Nothing is the same as there is no. Therefore, when heated, each mineral with a different coefficient of thermal expansion expands and breaks off the stone, causing cracks.

Unlike marble, it has excellent acid resistance, so it is often used for interior materials such as kitchens and kitchen countertops. It is important to note that the types of stone are quite different from the academic one and the way it is marketed.

Platonizes are magmas that slowly cool and solidify and are classified as a type of igneous rock. The feature is that the mineral grains are more significant than the volcanic rock where the magma suddenly cools and solidifies. It is further classified according to the amount of SiO2 contained.

Types of building stone

The types of natural stones are generally divided into granite and marble, but this is a very rough cut for the convenience of processing. There is none.

 Building stones and gravestone stones both require weathering, proof strength, weather resistance, strength, and hardness in stock, but building stones are used as additional structures, so whether they can withstand them. Is the point.

 Since natural stone is denser and flatter than concrete, which is one of the representative structural materials, it has a stronger compressive force. However, on the other hand, the parts used as building materials are limited because steel bars cannot be put inside or cast into molds, but in some countries, they are more common than concrete.

Chobe | What are These?

Building stones are cut into large blocks using blasting or wire from a quarry called Chobe and then cut into blades using blades. Besides, using a diamond wheel or a diamond tool for a stone called thickness determination, the thickness is adjusted, the surface is rounded, and the edge is rounded.

 Besides, the surface can be polished to a mirror-like state by rubbing, and building material with a stunning appearance can be finished. Currently, most are done by automatic machines, and when the plate material flows out of the line, polishing and grinding are finished when it comes out.

 In Japan, stone buildings are often large, but due to the inherent wooden culture, natural stone is not used as a building stone as much as overseas. Besides, because the place of production greatly influences the pattern of the rock, the color of the building stone is imported a lot because of the preference of the design.

In addition to specific gravity, water absorption, compressive strength, and other indicators that are required for building stone materials, indicators such as resistance to frost damage, weather resistance, and acid resistance may be necessary.

Igneous rocks are magmas that cool, solidify and crystallize. It can be roughly divided into three types depending on where it hardens.

 Rocks that solidify slowly while receiving heat and pressure deep in the ground are called plutonic rocks. Conversely, rocks that are rapidly cooled and hardened near the surface are called volcanic rocks, and rocks that solidify in the middle layer are called semi-plutonic rocks.

  •  Solidified near the surface: volcanic rock
  •  Solidified in the middle layer: semi-plutonic rock
  •  Solidified deep underground: plutonic rocks

 The components are basically the same, but their names and properties vary greatly depending on where they set and how fast they set.

A volcanic rock erupted from a volcano, which is exposed in the form of blocks (concrete: irregularly solidified), columns, or plates near the surface.

Andesite is composed of plagioclase, amphibole, etc. and is mostly gray-brown and has little luster. However, some have beautiful colors.

A stone made of igneous rock that is hard and has high durability and fire resistance. Therefore, it can be used for building exteriors and is a stone material that can be used in various places. Granite is the most abundant rock on earth and is mainly used for building exteriors.

Stone with a Madera pattern

Yes, that stone is often used as a living stone for graves. Have you ever seen nearby? In fact, it is a stone with a Madera pattern, and the granite itself has various colors.

The granite is a crystalline stone material whose magma deep underground is cooled and solidified in the crust. In the figure above, it is an igneous rock, and it is plutonic because it is solidified deep underground.

Granite is a stone material made of crystals such as quartz, potassium feldspar, and biotite. Have you learned this part at school?

Process Of Creation

Granite is also slowly cooled and hardened, giving it a strong hardness and aesthetic appearance, making it extremely durable compared to other stone materials. However, due to its hardness, construction processing costs tend to be high.

When magma is chilled, it may seem blackish, but not only black but also white, pink, and reddish granite. Those with white, pink, and red shades are called granodiorite and “white image,” and those with black are diorite (black magenta) and “black mirage.” Has been called.

White Mirage is the most commonly used stone material in Japanese tombs and is characterized by its large pattern. It is relatively inexpensive because it has a large amount of distribution.

 Granite is a stone that is mostly used for building exteriors because of its hardness, durability, and beauty. It may look fashionable even if it is used a little near the entrance approach or carport, as well as the outer wall.

in the process of accumulation and compaction of various thing our resulting product is sedimentary rocks

 Gravel, sand, clay, creatures of living things (corals, shells), etc. are carried to the bottom of lakes and seas by river currents, waves, and wind to form sedimentary rocks.

 Sedimentary rocks are not the only source of gravel and shells. Sedimentary rock is also formed by the accumulation of volcanic ash and debris, which are erupted when a volcano erupts.

Limestone is a rock made mainly of calcium carbonate and is a coarse-grained stone. A type of stone called sedimentary rock. It is a rock made by depositing shells, animal remains, pumice, volcanic ash, and volcanoclastic material on the surface of the earth.

 Since it is a stone made by depositing fine particles, it is relatively soft and easy to process. However, on the other hand, the strength is lower than other stones Rather than using it as the exterior, it is a stone material that you want to use as a building interior wall and floor material.

Sandstone is also a type of sedimentary rock. Quartz and Quartzite and feldspar are deposited in water as coarse grains.

 Generally, it is soft and easy to process and is fire-resistant because it is firmly pressed in water. In addition, although it has a strong characteristic against acids, its use on exterior walls is not recommended due to its high water absorption. Stones containing moisture can cause frost damage (frozen and crack) and can easily become dirty and moss-prone. Therefore, the sandstone used for the exterior is very difficult to maintain.

 On the other hand, the appearance changes slowly with the power of nature, so it is a stone that can enjoy aging. For those who can maintain it, it seems interesting to use it as a paving stone for the entrance.

The name tuff may not be familiar.

 Tuff is a solidification of volcanic products such as volcanic rocks, sand, and rock fragments deposited in water and on land. In other words, rocks coming out of the volcano are gathered and solidified.

 Since it is a lump of rock from the volcano, it has no luster, and since it is a soft stone, it changes color over time. Available in white, gray, and green-gray colors. Soft material and low strength make quarrying and processing easy.

 Because of its Great fire resistance, it is a stone material used for stone walls, stone warehouses, and hot spring rock baths. Making your own open-air bath with tuff is also full of romance.

Slate is a stone, also called slate that has a uniform, amorphous plate-like structure. It may not be a moderate way to understand, but anyway, it has the property of peeling off like a plate! A stone that is not formed by the accumulation of sand or rock-like other stones, but is formed by the precipitation and solidification of clay. It is a stone material that is often used for roofing because it is easy to process into a plate shape.

Speaking of materials other than building materials, it is a stone that is also used for inkstone when performing calligraphy. In general, it is black or reddish-brown like an inkstone, but green slate is also found. Stone materials classified as metamorphic rocks. Metamorphic rocks are formed by alteration of strata such as igneous rocks and sedimentary rocks due to heat and pressure caused by crustal deformation.

 In other words, rocks that have already been converted into rocks and undergo metamorphism. For this reason, metamorphic rocks undergo metamorphism and may become further metamorphic rocks.

Many of you may know this. Marble is also synonymous with high-grade stone. I want to say, “I’m a marble floor!” He’s a very bad guy. Marble is a decorative stone mainly used as interior material, as you might imagine. Granite is very hard and strong because it is a plutonic rock deep in the ground. However, marble is used as an interior material because it is softer than granite and can be processed in a short time.

The color of marble also differs depending on the calcareous contaminants, and marbles of various colors such as white, beige, gray, green, red, and black have been confirmed. It is not only plain but also features various patterns such as stripes and streaks from its origin. The shine of marble seen on TVs is created by thoroughly polishing the marble itself.

 However, it is a soft and delicate stone, so it is weak against weathering and is not suitable for outdoor use. If you are exposed to acid rain, the surface will lose its luster in about six months to one year, so be careful if you are considering using marble as an exterior. In order to keep that shine for a long time, you need to take good care of it.

Place where various stone materials can be used

Next, let’s consider “where can various stones be used for construction” based on the above properties. I would like to use it in places where each stone property lives.

Because it is a stone, the strength is definitely a concern. Stone with high strength can be used as wall material, but a stone with low strength cannot be used as wall material. The stone itself cannot withstand the weight of the building.

 In addition, whether or not it can be used outdoors depends on water absorption, so it needs to be examined. The table above is for reference only, and you need to consult with a stone shop where you use it. The stones that can be used will vary depending on the location, area, temperature, and humidity of the building.

Until I looked at it, I was thinking about “I think a stone house is cool.” But when I actually looked at the stone materials, I was surprised because there were various properties.

 Anyway, if you choose a marble that often hears its name, it’s OK! I was thinking about it, but marble is more delicate than I thought, and it must be carefully cared for. As expected, it is a luxury stone.

 Junior high school class? I have studied about granite, but I am surprised that this kind of granite is also used in tombs. That means that it is a strong stone with a large amount of circulation.

 Granite countertops are used to decorate the exterior walls of the building, marble if you want a gorgeous little interior, or slate if you want to use it for the roof. If you use them differently, you may come up with a new design from the difference in texture. My ideal is a tuff rock bath in the garden! A man’s romance!

 Granite is commonly called “granite countertops” and is a rock composed of minerals such as quartz countertops and quartzite countertops, feldspar, and mica with a particle size of several mm. There were various times when they were made, but they are widely distributed in the Chicago region.

It has been used since ancient times for stone walls, paving stones, and tombstones, and everyone will have seen it once. In addition, when the granite countertops, it becomes whitish and rough soil called “masa soil”.

This is also widely used in gardening. As you can see, granite is a rock that is closely related to humans. However, the weathering process from granite to Masato is more complicated than other rocks, and its mechanism has not been completely elucidated.

Granite countertops generally have vertical and horizontal cracks called joints. When water or air enters along the cracks, feldspar, mica, etc. turn into clay minerals and turn into “masa soil.” In areas where the crack interval is 1 m or more, untethered gravels called “core stones” (up to a few meters in diameter when large) forms a peculiar terrain with a rough rug. In the dense crack zone with a crack interval of several centimeters, water penetrates the entire bedrock and weathering progresses, forming a “deep weathered zone” consisting of “masa soil” from the surface to a depth of 100m or more.

 Weathered granite is easy to excavate, but also has the danger of disaster. Landslide disasters such as landslides and debris flows often occur on slopes that have become more soiled. There is also a risk of falling rocks in areas where core stones are dotted on the hillside. In addition, the rock itself can be very hard, but rocks surrounded by cracks and joints can collapse or slip.

 Thus, granite countertops show various expressions depending on the weathering form. We need to not only develop granite like the old people but also dwell on it.

First, we list the advantages and disadvantages of stone.


  •  High compressive strength (strength against pressing force) and high durability.
  •  Excellent fire resistance and heat resistance
  •  Some are polished by polishing.
  •  When used as a finishing material, it gives a solid design.
  •  There are many types and designs of various tastes.


  •  The tensile strength and bending strength are smaller than the compressive strength.
  •  Inconvenient to transport compared to other building materials.
  •  Difficult to process compared to other building materials.

Looking at the advantages and disadvantages in this way, you can imagine what kind of place stone is suitable for. For example, it can be used for walls subject to pressure in the compression direction.

However, even if you say stone supplier, the performance is different for each type. Let’s look at them below.
