.....But there's one little caveat that no one seems to have
mentioned. You really should use_Distilled Water, not tap water....
G’day all; Distilled water bought from a pharmacy or a laboratory
usually IS distilled - or at least deionised, which is just as good.
I know garages and service stations sell distilled water, but I am a
little wary - partly because I have actually seen one of the folk who
work at a garage top up the bottle from the tap, though the bottle
was clearly marked DISTILLED WATER. If you can’t get distilled or
deionised water, then rain water will be good enough to use for most
My house is not on the town supply reticulation, and we use rain
water collected from the roof into a 6000 gallon underground concrete
tank. When we first moved in the water was very ‘hard’ because of the
calcium leaching out of the concrete, but this cleared after about a
year, and the total solids content of the water is very low indeed.
Not as low as distilled water of course, but quite satisfactory for
making up solutions of chemicals used in jewellery work. – Cheers now,
