Salt
'Salt' symbolizes the desire of truth and good to be conjoined with each other. So, a salt can conjoin water, which corresponds to truth, with oil, which corresponds to good.
Salt can also have a negative meaning. 'Lot's wife becoming a statue of salt' signifies all the good of truth being vastated, or laid waste, in the church that Lot represented. In that story, Lot's wife represented a form of 'truth' that turned itself away from 'good,' and looked instead to doctrinal matters. Because 'salt' can signify vastation, and 'cities' signify doctrinal aspects of truth, in old times they sowed cities with salt when they were destroyed to prevent them from being rebuilt, as in Judges 9:45

2 Kings 2:19-22
19
The men of the city said to Elisha, "Behold, please, the situation of this city is pleasant, as my lord sees; but the water is bad, and the land miscarries."
20
He said, "Bring me a new jar, and put salt in it." They brought it to him.
21
He went out to the spring of the waters, and threw salt into it, and said, "Thus says Yahweh, 'I have healed these waters. There shall not be from there any more death or miscarrying.'"
22
So the waters were healed to this day, according to the word of Elisha which he spoke.
