Trying to put together some bumph on the mineral content in water, I decided to plagiarise the small print on a bottle of still mineral water.
Amongst the "menu" of minerals and their amounts per milligram/litre there was T.D.S at 180oC 190 As far as I know, water turns to steam at 100oC and then evaporates. Does this "190" mean that there's no water left and that's what the ppm would have been in the water at source?
Or something else?
Anybody got a clue . . .
