In July 1970, the artist John Baldessari loaded a group of his own paintings into a crematorium in San Diego. The works dated from 1953 to 1966 and represented more than a decade of his early career.

Instead of storing them or selling them, Baldessari chose to destroy them completely. The paintings were burned, their remains collected as ashes, and the residue was placed into an urn. The project was not a private act of frustration. It became a formal artwork titled The Cremation Project (1970)—a work that marked a decisive break in Baldessari’s practice.

Before he became associated with conceptual art, Baldessari worked primarily as a painter. He had studied at San Diego State College and later attended programs at Otis Art Institute and Chouinard Art Institute.

During the 1950s and early 1960s he produced canvases influenced by abstraction and postwar American painting. These works circulated within the regional art scene in Southern California, but Baldessari gradually became dissatisfied with painting as a format.

By the mid-1960s he began incorporating text, photographs, and language into his work—moves that aligned him with emerging conceptual practices. The earlier paintings no longer represented the direction he wanted to pursue.

The Cremation Project was a way of closing that chapter.

The procedure was documented carefully. Baldessari gathered every painting he had produced between 1953 and 1966 that remained in his possession. The works were transported to a crematorium and burned.

The ashes were then divided into several components that together formed the artwork.

Part of the residue was placed in an urn. Another portion was used to bake small cookies—an action recorded in a bronze plaque that lists the ingredients and dates of the cremation. Baldessari also produced a book documenting the project.

Rather than presenting the destroyed paintings, the artwork consists of the records of their destruction: the urn, the plaque, the cookies, and the documentation.

The Cremation Project appeared at a moment when conceptual art was redefining what counted as an artwork. Artists such as Sol LeWitt and Lawrence Weiner were arguing that ideas could take precedence over physical objects.

Baldessari’s gesture extended that logic. The physical paintings were removed entirely; the concept and documentation remained.

Within a year he produced one of his best-known works, I Will Not Make Any More Boring Art (1971), a text-based project first executed as a video and later as wall writing. Throughout the 1970s he continued combining photographs and language in ways that questioned how images produce meaning.

The cremation therefore functioned not only as a symbolic act but also as a practical reset for the work that followed.

In retrospect, the project has become one of the most widely discussed gestures in conceptual art. Baldessari later taught at California Institute of the Arts, where his teaching influenced younger artists including David Salle and Mike Kelley.

The destruction of the early paintings reinforced a principle that shaped his later work: the artwork does not have to be a permanent object. It can be an action, a document, or a set of instructions.

Museums that exhibit The Cremation Project today show the urn and the bronze plaque as relics of an event that eliminated its own material past.

For Baldessari, the cremation was less an act of erasure than a form of editing. The paintings from 1953 to 1966 were not hidden or forgotten; their disappearance became the subject of the work.

In this sense the project resembles a ritual more than a critique. A career’s early stage was formally concluded, documented, and transformed into a new artwork.

What remains is not the paintings themselves but the record of the moment they ceased to exist.
