Everything we have comes from the Earth. If it doesn't grow, it has to be dug up and processed.
Minerals are mined: gold, silver, diamonds, halite (salt), haematite (iron, steel), bauxite (aluminium), anthracite (coal), cassiterite (tin).
Rocks are quarried: marble (statues), limestone (construction), granite (kerb stones), sandstone (pavements).
Minerals and rocks can be very pleasing to the eye and to the touch. HHGS members display their favourite pieces at the Uxbridge Rock Show each year. Examples are shown in the Art Displays below. For 2021 our new display is about Industry.
