Caption: Scanning electron micrograph of fur from a domestic kettle, showing the crystals that form in a hard water area (Norwich, Norfolk). The fur consists of crystals of calcium carbonate (pebbles) & crystals of calcium sulphate (needles). Hardness is caused by calcium salts. When water containing calcium bicarbonate is boiled, the soluble bicarbonate breaks down to give the insoluble calcium carbonate. When water containing calcium sulphate is evaporated, boiled or dries out, the calcium sulphate percipitates out of solution. Magnification: x600 at 10x8 inch size x170 at 6x7cm size.
