Granite worktops are solid surfaces formed by the cooling down of molten lava under the earth's crust. They are formed from igneous rock consisting of hornblende (black grains), mica (dark/ golden sparkly grains), quartz (round glassy grains), and feldspar (Opaque, prism-shaped pink and white). It has a phaneritic texture meaning the crystal deposits are clearly visible without an observational aid for magnification. The mineral composition of the igneous rock gives colour to it. Granites are widely used in many objects we see in our life.
