Anyone know where to get bulk sea salt?

[dissimilus]

I'm looking for cheap industrial grade, not fancy "food safe" sea salt. Needing about a gallon or so for metalurgy pursuits and don't want to buy a gazillion little containers at QFC.

Just for funzies I may eventually see just how much I can get from evaporating a gallon of water from the sound, but for now I'm lazy.

We (work) just bought 50 lbs at PetCo (for sea-water fish people)

Oh, right! Duh, I used to take care of 1000 gallons of salt fishies for work. Shoulda remembered. They all seem to have "formula" additions these days, but hopefully if I find the cheap stuff it'll just be close to plain old sea water and will have the chemicals I need. I'm playing around with case hardening steel via the "poor man's" heat-and-quence-in-seasalt method. we'll see how it goes.
