Is line a sedimentary rock?

Line is a sedimentary rock made up of the calcium-carbonate shells of tiny, long-dead marine animals. The convective flow patterns you see in Cream of Wheat and in gold concentration processes are called hydrothermal cells. For gold these cells can be vast in size, stretching more than 10 kilometers across.

Why is line so expensive?

Similarly, Line used for specialty applications or niche markets may have a higher price. If a certain type of Line is rare or difficult to find, it becomes more valuable. And since it becomes more precious, it also becomes more expensive. The size and weight of the line rock also factor into its price.
