Originally built as a factory that housed Val-Kill Industries, Val-Kill Cottage soon became Eleanorâs cottage. Eleanor Roosevelt was a highly dynamic, broadly effective, and controversial first lady. While her husband was alive, she used the cottage as her personal retreat. When he died, she made it her permanent home.
Granite is composed mainly of quartz and feldspar with minor amounts of mica, amphiboles and other minerals. This mineral composition usually gives granite a red, pink, gray or white color with dark mineral grains visible throughout the rock. Granite is the best-known igneous rock.
Weathering also breaks apart granite into piles of individual mineral grains called grus, which are then swept away into streams where they become sand. Play sand and beach sand, as well as the sand in sandstone, is largely quartz and feldspar grains produced from weathered granite.ranite contains mostly quartz and orthoclase feldspar; other minerals make up less than half of the rock. The magma that crystallizes into granite likely forms in the upper mantle or lower lithosphere, where other rocks partially melt. Granite is used in buildings and some granite is mined for rare elements.
