Marble, CaCO3 will not usually scratch glass, but maybe a very soft glass.
Marble has a hardness of 3 to 4, whereas glass is 4.5 to 6. (in a relative hardness scale.)
A glass child's marble is made by dropping a small slug of semi liquid glass into the space between the pair of rounded grooves, that spiral away along a pair of rollers. Emerging as a round marble, and now cooler.
Marbles originated in ancient Rome and Egypt and were made from marble (rock). However this was expensive so people tried to find alternatives and in 1846 a German glass blower invemnted a marble made from glass.
little round things usually made of glass about 7/16 inch in diameter used in games
The number of marbles in a glass depends on the size of the glass and the size of the marbles. For example, a small glass might hold around 20-30 standard-sized marbles, while a larger glass could accommodate 50 or more. To determine the exact count, you would need to measure the volume of the glass and the volume of a marble.
Not if it is a glass marble, but you can get metal marbles which would be magnetic in many cases.
The marble will sink.
Th material can be very differernt: glass, porcelain, agate, steel, marble, etc.
no
Because the marble has a higher density than the water does
When a glass marble rolls down a ramp, gravitational force acts on it, causing it to accelerate. As the marble moves, its potential energy is converted into kinetic energy. Friction between the marble and the ramp may also slow down the marble's acceleration.
It is called an agate or an aggie.
gravity
The center of a marble typically consists of a small piece of glass, clay, or a solid core material, which is surrounded by layers of colored glass or plastic.
No, glass is not a material that is attracted to magnets. Magnets can attract materials such as iron, nickel, and cobalt, but glass does not contain these magnetic properties.
You can try using a suction cup or a piece of duct tape to lift the marble out. Alternatively, you could fill the vase with water to help float the marble to the top for easier removal. Be careful not to damage the vase or yourself while attempting to remove the marble.
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.
What size marble? And is it made of marble or glass?
