My experience with a 15/60 NST coil is that NaCl will do a fine job in
turning the base of the streamers a nice yellow color.  I balled up a
small piece of wet paper towel and dipped it in the salt to form a
salt-covered breakout bump on my toroid.  It didn't matter that the bump
was wet.

One thing I should warn about is that salt dust will be sprayed all over
the toroid and everything below.  This may not be good for surface
finishes, particularly aluminum toroids and primary turns.

In a Jacobs Ladder there is sufficient current to heat
the metal compounds (such as NaCl) to break it down
and in effect burn it in the arc.  With a tesla coil I don't
believe there is sufficient current on the top terminal (average
power TC) to heat the compound to combustion.

However, there are some interesting effects using gases that
can be ionized by the streamers such as Argon.
