Yes, it is but my own attempts with realgar etching haven't been very successful. I gave away my arsen when my first child was born.
Yes, i have never used it, but my understanding is that realgar is not at all consistent in its quality. Shame you felt the need to get rid if your arsenic supply. I would have thought a good lock box or safe might have solved your problem there.
