plaster of paris
Hi from Canada:
I vaguely remember reading somewhere in "The Krib" that plaster of paris
can be used as a source of calcium sulphate to be used in buffer
solutions for reconstituting RO water.
If memory serves doesn't plaster of paris also contain calcium
carbonate? I have no idea of the proportions of the two.
Can anyone shed light as to wether using plaster of paris is a good or
bad idea or suggest implications, recommendations etc?
