Derived from the damar fir tree, these "tears" of resin are dissolved using a solvent to make a spirit varnish. This natural resin varnish has been in use for hundreds of years but has a tendency to yellow and become brittle over time.
Head-tested oils, varnishes (either natural resin or synthetic resin), cellulose lacquers, chlorinated rubber and spirit varnishes are among the materials which are used to manufacture this type of paint.
