[1] Baltzar's first novel Polttava tie, "The Burning Road" (1968, published in Swedish 1969 as Brännande väg) was successful and brought attention to him.

Baltzar has also written a novel for children about Gypsies (Mustan Saaran kristallipallo, The Crystal Ball of Black Sarah) in 1978.

Phuro, published in 2000, is an extensive epic novel about the Roma living in Central Europe, the saga of a family, which tells a tale of the community through that of the relatives.

The premiere of so-called "second" Orli, patronaged by Finland's Prime Minister Paavo Lipponen, took place in the Finlandia concert hall in March 1997.

When Baltzar started managing his own theatre and teaching / directing in 1976, he created his own pedagogical method based on multicultural emotional intelligence, known as Intercultural Experiential Education.

In 2012, Baltzar published a polemic work Towards Experiential Philosophy (Kokemuspohjainen filosofia in Finnish), in which he introduces his pedagogical method and its philosophical and educational background.
