Nerine sarniensis

Sorry for the confusion over names. Chemicals are a bit like plants,
there is the formula K2SO4, the normal (English) chemists name,
potassium sulphate, an older version, sulphate of potash, and an even
older, muriate of potash. Traditional gardeners and agriculturists might
use either of the two latter names, but as an analytical chemist by
training I can only think in terms of the first name. If someone asked
me for muriatic acid I would have to get a dictionary out, to find it
was sulphuric acid. And then if you travel and have to use another
language you sometimes find the translation better fits what you thought
of as the trivial name in English. Using the wrong plant in the garden
can be annoying, using the wrong chemical in industry can be dangerous.


I can see there is no point in using analytical grades of potassium
sulphate on the grounds of economics, but cannot see your reasoning as
regards impurities (added elements?) in agricultural/horticultural
grades of potassium sulphate. The SRGC is referring to 0:0:50 inorganic
powder or crystals with nothing else added, as a bulb "booster".
