PETER ALEXANDER | LUMINOUS FORMS

LUMINOUS FORMS

by Sharrissa Iqbal, Ph.D.

Throughout his sculptural career, Peter Alexander maintained an organized series of notes detailing the casting of specific resin artworks. Documenting the temperature and humidity levels during his casts, these records highlight the close interrelationship between Alexander’s artworks and the physical context in which they were produced. The artist’s process required an acute awareness of how ambient conditions actively shaped the outcome and appearance of each finished cast. Just as each of his artworks indexes a particular combination of material variables and environmental factors, Alexander’s larger practice reveals further interconnections between his works and the combined natural and cultural climates from which they emerged.

Alexander’s transparent and translucent volumes of cast polyester resin respond to the conditions of their surroundings, shifting in appearance with changes in lighting, setting, and a viewer’s position in relation to the work. Light passing through the material is transmitted, reflected, and refracted, generating fields of color, depth, and shadow within and extending beyond the physical boundaries of the object. Across his works, solidity and transparency coexist. Viewers can recognize the sculpture as a discrete form while simultaneously looking through it, creating a visual tension between objecthood and immateriality.

Beginning in 1965, Alexander first explored the possibilities of casting liquid polyester resin to create precise geometric forms including cubes and rectangular blocks. The artist’s choice of polyester resin took shape within the particular material culture of postwar Southern California, where aerospace engineering and petrochemical industries contributed to developments in the production of plastic. While Alexander’s familiarity with polyester resin came through his experience using the material to repair surfboards, he considered its aesthetic possibilities while studying sculpture as a graduate student at UCLA. From his earliest sculptures in cast polyester resin, Alexander created environments of color and depth, employing geometric simplicity as a controlled framework for exploring complex optical phenomena and creating sensory experiences.

Alexander created his cast resin boxes as environments that he imagined viewers could visually enter into. This spatial conception of sculpture drew in part from the artist’s prior training in architecture, which required visualizing three-dimensional spaces through drawings and models based on rectilinear geometric forms. By adjusting variables during the casting process, Alexander created a wide array of internal effects within his sculptures. With variations in transparency, embedded forms, and carefully modulated color, he experimented with color and degrees of opacity and transparency. Early investigations include resin cubes containing nebulous shapes in wax that appear to float within a small cubic section of a synthetic sky. Similarly, the light haze produced in Untitled, 1966 seems to recreate on a small scale an expansive visual effect frequently seen in the sky. In Untitled, 1968, a nearly transparent sphere is suspended within a similarly tinted block, generating complex visual phenomena as the boundaries between forms become difficult to distinguish from different angles. Another work consisting of a shape within a shape is Untitled, 1971, where a murky blue rectangular prism cast within a slightly larger and more transparent outer block creates a glowing edge around the darker internal form.

Inspired by aerial views of the California coastline, Alexander’s wedges including Untitled, 1968 translate a visual experience of ocean water into sculptural form. The gradual shift from thick to thin creates a subtle transition between density and transparency, allowing viewers to perceive volume in much the same way they might perceive the changing depths of the sea from a view above. Raised in Newport Beach, Alexander spent much of his youth around the ocean. Throughout his career, the visual and sensory experience of water remained fundamental to his artistic imagination. He later recalled being attracted to liquid resin because of its resemblance to water itself. Alexander’s wedge sculptures transform a simple geometric form into an experiential encounter with light, depth, and color, connecting abstraction to the perceptual realities of Southern California’s coastal landscape.

Alexander’s career occupies a central place within the broader context of the emergence of West Coast Minimalism and Light and Space Art in Southern California. By the late 1960s, Alexander had gained considerable recognition for his work, leading to his appointment as an artist-in-residence at the California Institute of Technology between 1970 and 1971 alongside Helen Pashgian, Robert Bassler, and David Elder. The program reflected a broader cultural interest in fostering dialogue between artists and scientists. For an artist already working with industrial plastics and technical fabrication processes, Caltech offered an environment in which artistic experimentation could unfold alongside scientific research. Although the residency does not appear to have fundamentally altered the direction of Alexander’s work, it reinforced the close relationship between his practice and the development of new postwar material technologies in Southern California.

The same material that enabled Alexander’s artistic breakthroughs ultimately forced the artist to abandon sculpture in 1972. After becoming seriously ill from prolonged exposure to polyester resin, he stopped working with the material entirely for nearly 40 years. The decision marked a dramatic interruption in what had been a remarkably innovative period of sculptural production. Alexander later spoke of both his fascination with resin and his dislike of its physical properties, such as its toxic fumes, persistent odors, and the dangers associated with its use. His experience reveals a central contradiction within postwar California culture. The synthetic materials celebrated as symbols of progress and innovation often carried hidden environmental and bodily costs. Alexander’s career thus reflects a broader cultural shift from uncritical enthusiasm for new technologies towards greater awareness of their consequences.

After focusing primarily on painting and printmaking for over three decades, Alexander returned to sculpture in 2009 when advances in resin technology made it possible to work more safely with a reformulated version of the material. New resins like urethane offered greater optical clarity, stability, and color saturation, allowing Alexander to revisit the geometric structures that had defined his early career while expanding their perceptual possibilities. Rather than simply recreating the sculptures of the 1960s and 1970s, his later works from 2009 to 2020 demonstrate an artist continuing to investigate the relationship between material and perception under new technological conditions.

The sculptures created during this later period reveal both continuity and transformation. Alexander returned to familiar forms, including blocks, tapered wedges, pyramids, and bars, but often imbued them with intensified color. At the same time, he expanded his sculptural vocabulary through new configurations, including wall-mounted squares like Untitled, 2013. These works continue his exploration of how light moves through and around objects and their surrounding spaces, creating experiences that shift between physical presence and optical immateriality.

Viewed across the full span of his career, Alexander’s sculptures attest to an artist whose ideas were inseparable from the materials through which they were realized. Polyester resin was not simply a means of achieving particular visual effects, but also a changing technology that expanded the possibilities of interactive artworks in the 1960s. Through his sustained investigation of this Space Age material, Alexander created sculptures that occupy a space between nature and technology while also blurring the boundaries between object and perceptual experience. His works recall the sensory experiences of light interacting with air and water, revealing how one’s perception of atmospheric density itself could become the subject of sculpture.
