In the 1960s, Adolph Gottlieb's art continued to evolve, marking a period of significant innovation and experimentation. This decade is characterized by the refinement and expansion of his iconic "Burst" series, which he had initiated in the late 1950s. The "Burst" paintings are known for their bold simplicity, featuring a radiant orb above a field of gestural brushstrokes or a tangled mass, suggesting cosmic landscapes and the dichotomy between order and chaos. These works are a further exploration of the themes of opposition and balance, central to Gottlieb's artistic inquiry throughout his career​ (The Art Story)​. Gottlieb's art in the 1960s reflects his ongoing interest in creating a visual language that could express complex emotional states and existential questions through abstract forms. The decade saw him pushing the boundaries of this language, exploring variations in color, form, and scale that engaged viewers in a direct and immersive experience. The "Burst" series, with its vertical orientation and large scale, placed the viewer in a direct physical relation to the artwork, enhancing the impact of the abstract forms and colors on the viewer's perception and emotional response​ (Frisson Art Gallery)​. An exhibition at Galeria Elvira González titled "Adolph Gottlieb: 1960s," held in Madrid in 2004, showcased Gottlieb's artistic development throughout the decade. The exhibition featured works that illustrated his exploration of the relationship between the background and the burst, a theme that became a hallmark of his style. This body of work was diverse in execution but unified by a common exploration of the dynamic between formed and unformed elements, symbolizing the interplay between cosmos and chaos​ (Adolph & Esther Gottlieb Foundation)​. Gottlieb's work during the 1960s is also noted for its conceptual depth, as he continued to explore the existential themes that had occupied him throughout his career. The simplicity and abstract nature of his compositions from this period belied their emotional complexity and the depth of Gottlieb's engagement with the fundamental questions of human existence​ (Adolph & Esther Gottlieb Foundation)​. The 1960s stand as a testament to Gottlieb's enduring impact on Abstract Expressionism and his relentless pursuit of an art that could communicate the depths of human experience through abstraction. His work from this period reflects a mature articulation of his philosophical and aesthetic concerns, making a significant contribution to the development of modern art.
