Anorthosite typically has a coarse-grained texture, with individual mineral grains that are easily visible to the naked eye. It often appears as a mottled combination of white, gray, and black minerals, with a crystalline structure that can exhibit cleavage planes.
The debris of boulders and coarse material carried by glaciers is known as moraine. Moraines can be found at the edge, sides, and base of glaciers and are deposited as the glacier moves and melts. They can vary in size and shape depending on the glacier's movement and the type of material being transported.
When ever heat is applied there occur a change in grain structure.The best working temperature for steel is between 400 - 750 c. If steel is heated below 400c and then cooled it results a brittle zone. And above 750c heavy oxidation losses occur. If rate of cooling is fast it will result in fine grain structure and material will become hard. If rate of cooling is slow coarse grain structure is formed and material will be ductile.
The lustre of conglomerate is typically dull to sub-vitreous. It usually appears as a coarse grained rock composed of rounded pebbles or cobbles cemented together with a finer-grained matrix. The lustre may vary depending on the composition and size of the individual pebbles and the matrix material.
The most coarse sandpaper grit size typically starts at around 40 or 60 grit. These lower grit sizes are used for heavy material removal on rough surfaces.

My dress was made out of coarse material.
coarse pearlite structure has better ductility and toughness compared to fine pearlite structure but fine pearlite structure has better strength compared to coarse pearlite structure.
Gives an indication of the relationship between fine material and coarse material in a gravel mix. The higher the GM the more coarse material.
Reactive power is the coarse that is reactive with water. This a developing composite material.
Burlap is a coarse material. She enjoys the feeling of coarse sand between her toes. His coarse beard tickled his daughter's face as he hugged her.
linsey - it is a thin coarse blend of linen and wool
A coarse texture refers to a surface that is rough or uneven to the touch. This can be visually identified by larger particles or grains that make up the material. Materials like gravel, sandpaper, or certain fabrics can possess a coarse texture.
It's used to make burlap cloth, which is a coarse sacking material.
Anorthosite typically has a coarse-grained texture, with individual mineral grains that are easily visible to the naked eye. It often appears as a mottled combination of white, gray, and black minerals, with a crystalline structure that can exhibit cleavage planes.
Gneiss which is a non-foliated meta-igneous rock is coarse grained in texture.
This is known as glacial till.
