A type of rock or pottery that contains a lot of iron, often used for making things like pottery or for extracting iron ore.
The artist chose to use ironstone for her pottery because of its durability and unique color.
Ironstone is formed from "iron" (from Old English "iren", meaning a strong, hard metal) and "stone" (from Old English "stan", meaning a solid mineral matter). The word refers to a type of stone that contains iron or has iron-like properties.
Think of 'iron' as a strong metal and 'stone' as solid material — together, they describe a stone that has iron in it.
