Not table salt however, more like the crystals you would grow in a science experiment.
Although it is often so small that I guess you could say salt and be pretty close. Definitely not like
some kind of plant that has fuzzy branches, although plume can stalk a little as crystals grow
undisturbed, but they would not look fuzzy.
