Mother liquor

Mother Liquor is a chemical name for the part of a solution that is left over after crystallization.

It is also an important process in the creation of cigarettes.

After reprocessing of unsold cigarettes, introduction of new tobacco, and a chemical process to bring this mix down to a liquid, it is sent to a large tank that creates the Mother Liquor. Later this concoction is sprayed on paper for introduction to new cigarettes.
