Need rock salt ?

[i-leonardo.livejournal.com]

I needed rock salt for metal working and the smallest container I could find was a 40# bag of the stuff, labeled "Morton's Whitecrystal Water Softener Salt".  It claims to be pure rock salt (large grain) suitable for use in a home water softening system.  I don't know anything about water softening, but I can assert that it's just fine for small-scale casting and soldering metal.  After taking what I need, there's still somewhere between 10 and 15 pounds in the bag.  Would much rather give it to someone else than surreptitiously add it to the city's snow removal pile under the deck of 93 near assembly square.

it will snow again so why not wait until then to use it?

Get yourself a plus-size box of ziploc bags, couple pounds of sugar and a stream of dairy and invite a bunch of friends over to shakey-shake their way to ice cream heaven. Tell them to BYO flavorings.

the ice cream suggestion is the best (no idea @ the ziplock bag method) - but I'm curious how you used the salt for casting (and soldering??). Any links to technique?

Water softener salt? I suppose that means it is food-grade. How large are the crystals?

(I have no need for it myself.)

When winter approaches, you can always offer it free on CL.
