All true marble is metamorphic, regardless of its color.
Traditionally the best marble was always prized for being white.
The force that causes a marble to sink in water is gravity. The weight of the marble is greater than the buoyant force acting on it, causing it to sink.
Marble comes in every color imaginable. It can be a chalk-white to a onyx-black. It can be calico colored as well from every color including different colored cyrstals to add to the mix. Marble for exterior use is normally white.
The most expensive color for marble is typically pure white or a light, consistent color without veining or other imperfections. These types of marble are considered more valuable due to their rarity and clean appearance.
it is hard and different in color
Marble is commonly white, but it can also be found in various colors such as gray, beige, pink, and green. The color of marble is determined by the minerals present in the rock and can vary depending on the location where it is quarried.
The force of gravity
A bluish marble looks exactly like the Earth, with some swirls of color white scattered along the surface.
Composite marble is made by mixing at least 90 percent of natural marble chips or powder with polyester resin and color pigment. It is generally formed in blocks with the size of around 120x300x85cm and is cut and polished as of cutting natural marble. The original idea of inventing composite marble is to eliminate the downsides of natural marble such as inconsistency in color, porosity, color limitation,uncontrollable veining, etc. Composite marble has gained popularity among designers for its compatibility with today's modernity.
The force of gravity is what causes the marble to sink to the bottom of the glass of water. Gravity pulls the marble downward towards the center of the Earth, overcoming the buoyant force exerted by the water.
