low temp salt

[blade runner]

If any of you guys heat treat with low temperature salt (600 degree range), where do you get your salt from?
I'm having trouble finding it.
Thanks.

I and others use the Nitre Blue salt from Brownells. The good thing about it is it plays double duty for blueing. It also hardens to a nice clean brick when not in use.

At a recent hammer-in, I asked Randall Graham where he got his low temp salts, he said www.heatbath.com
I've no idea about minimum orders, prices, etc but in looking through their web site, they have a wide range of salts and quenches.
I'm going to shoot them an email to see what their prices and minimums are for low temp salt as I'm going to build one myself.
