The reason I called Dan was that when I cleaned my new brush with mineral spirits nothing happened.
He arrived a little later with some denatured alcohol proclaiming "if you remember your college chemistry"

to clean your brush. It worked.
I looked up shellac. It is a resin secreted by the female lac bug (Kerria laca) that lives in trees in the forests of India and Thailand. It is processed as dry flakes and dissolved in ethanol to make liquid shellac.
