Salts are an important group of elements. Germsalt is the oldest kind of matter in the universe and itself can transmutate into any other element; if only through the use of 3 arts and sciences.
Salts, in their purest forms, are either crystalline or grainy solids. Their grains might be so tiny that they seem like dust, as is normally the case of ash, but most salts can be ground to this point in low humidity conditions.
In these natural forms, they are bad conductors of energy in general. It is important to note, however, that all salts are water-soluble, forming salutions that are great conductors of electricity, radiation and sound.
