Moraine or glacial till.
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.
They grade blasting sand based on its overall ability to remove material. Larger, more coarse material can quickly remove a surface but may also damage the under layers.
You use netting from fabric store. It's cut into various widths and crochet or knitted.

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.
My dress was made out of coarse material.
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.
The sandpaper had a coarse texture, making it ideal for removing tough stains.
linsey - it is a thin coarse blend of linen and wool
Moraine or glacial till.
It's used to make burlap cloth, which is a coarse sacking material.
Gneiss which is a non-foliated meta-igneous rock is coarse grained in texture.

This is known as glacial till.
