...My kitchen sink is leaking because, over time, London’s tap water, which is heavy on minerals, has caked up its inner workings with deposits of calcium....
...At the former, a cascade of sulphuric waters with a preponderance of calcium carbonate deposits delivers on both therapeutic benefits and photo-ready scenery: the sulphur eases muscles, while the calcium...
...Polyhalite combines four of the six macronutrients essential to plant growth: calcium, magnesium, potassium and sulphur....
...Anglo is poised to acquire Sirius Minerals, a UK-listed company that has been struggling to develop a giant potash deposit under a national park in North Yorkshire....
...Polyhalite, from the Latin “many salts”, combines four of the six macronutrients essential to plant growth: calcium, magnesium, potassium and sulphur....
...magnesium, sodium and calcium....
...Sharks and rays usually reveal their ages through the calcium deposits laid down each year in hard structures such as fins, but Greenland sharks, the largest fish in northern waters, have no such structures...
...The polyps, which excrete calcium carbonate to make reefs, are hugely sensitive to changes in water temperature and sunlight....
...“You can produce bits of structure that are as strong as reinforced concrete but it’s all grown in seawater using available calcium carbonate and magnesium hydroxide,” he says....
...When water finds its way into cracked concrete, the bacteria activate and eat the resultant calcium lactate, secreting limestone, which closes the cracks in less than a month....
...The tiny marine invertebrates, or polyps, that excrete the calcium carbonate to make coral reefs are extraordinarily sensitive to changes in water temperature....

...Polyhalite comprises calcium, sulphur and magnesium as well as potash, a vital ingredient in fertiliser....
...The deposit was polyhalite, which has less potassium than sulphate of potash, mined elsewhere, but contains other minerals such as magnesium, calcium and sulphur vital to plant growth....
...In the rather fabulous penthouse that I was lucky enough to borrow, I discovered a startlingly efficient tool to scrape the water and calcium deposits off the glass shower wall....
...As bank deposit rates decline, most of us spend more. The Chinese tend to stash away even greater sums to make up for the lost interest....
