Some Kosher salt contains a small amount of sodium ferrocyanide to prevent caking. I have found that the best bet for pure sodium chloride is pickling salt. Since it is desirable that brines are perfectly clear pickling salt contains no additives. The downside is that this form of salt may only be available part of the year during canning season. Buy it when you can.

The Iodide will combine with the Silver nitrate and form a precipitate. Kosher salt is pure sodium chloride but check the package to make sure. --- Richard Knoppow Los Angeles, CA, USA dickburk@xxxxxxxxxxxxx ======================================================================== ===================================== To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there. ============================================================================================================To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there.
