So salt is important and a 1kg bag from the shops will last ages for cooking. But what about tanning, raw hide and a salt supply that lasts forever, does anyone know how pure pool salt is and if its suitable for these applications? Its dirt cheap and readily available atm. Is it worth buying a bag?

I'm not entirely sure of its applications of whether its safe for consumption. Will leave this one up to someone else to answer.

I was meant to do this guys, my bad. regular table salt is NaCl Sodium Chloride. Pool salt "MAY" contain other additives but it would be pretty clearly stated on the packaging. If you can get the MSDS for it, which it should be readily available for whichever specific brand your buying then you can look under the composition section, if it is 100% Sodium Chloride followed by a CAS number and when you look up that CAS number it is simply food grade salt then it "SHOULD" be fine. You would also need to watch how it was processed and packaged. It may have been packaged on a line containing trace amounts of something nasty that won't be an issue in your pool but will be if you directly eat it in more concentrated amounts.
Like I said, I was meant to do this as it was discussed in another thread, but I forgot. I'll make it my project over the next week as a bag of pool salt is about $7.50 for 25kg the crystals are pretty chunky but that's what a grinder mill is for.

Its my understanding that most salt in Australia is made from evaporation of sea water
The more pure salt is for human consumption the less pure I.e contaminated with soil etc is for pools etc
I have stored some as it is cheap and useful for salting preservation
I don't think contamination from soil would be harmful for such uses
Any thoughts or comments?

I usually have a few bags for weed control  currently have nearly 10kg of cooking salt in the pantry so am set in many ways. When I restock my pool salt I think I will just contact the manufacturer. |

With a 2kg bag costing $1.79 (from memory) at Costco, I'm grabbing a bag each time I visit. Got 10kg to hand so far.

salt isn't too pricey. So a Kg bag every now and then should have you getting enough for a long time.
maybe learning how to distill sea water using a solar still would be good. Water + Salt for non cooking purposes.

yes, that would be a problem  For me, I'm surrounded by sea water, albeit, not clean sea water. |

A few years back one of the first projects that i had a crack at was desalinating sea water. The trial was a success and what i was left with was the salt residue sitting in the bottom of the pot. Over the holidays i decided to repeat the process and this time use the salt sludge residue and make my own salt. Using 2 Litres of seawater which was boiled off to sludge i then placed the residue in a container and left it outdoors in the sun to dry. The drying process only took 2 days as i placed the container on top of our gas hotwater vent . If you were drying with the sun i'm guessing 4 to 5 days. You can see the process below from sludge to crystals. Salt will be an invaluable commodity PSHTF and the ability to make your own will one day come in handy. TIP: Next time i will strain the seawater to remove sand particles!!    |

Pool salt can be consumed in small amounts if you need to but normal salt isn't to expensive so I'm stocking up on that. Learning to distill sea water is a good idea but you won't get just salt from that, you'll be getting all the sea bugs too.

Pool salt is ok for consumption, but for tanning, salting meat etc: refined salt is easier to use! 10-20 kg bags can be purchased from any bulk food distributor for around $10-15 for 10kg and $20-25 for 25kg bags!

When you add pool salt to a pool, there's a foam of crappy scum on the surface of the water. I buy salt intended for consumption. If you speak with someone who regularly gets salt from a wholesaler (eg pool shop, butcher, etc), they may be willing to order a couple of bags for you. I've bought butcher's salt this way before.
