In terms of technique, Milhazes is predominantly concerned with the principle of collage, drawing from her combined knowledge of both Latin American and European traditions. The cultural mixing of her native Brazil is something Milhazes is aware of and to some degree communicates in her paintings as well as being in ties with the Brazilian modernist movement. Milhazes many other influences come from her own fascination with the decorative arts, fashion, and geometry. Milhazes has described her own work in saying "I think of my work as geometric, yet I can't put everything into a square or a circle." Her self-developed process of art making came about during her extensive researching of printing processes in the 1980s. A slow but steady process, time is key to everything for Milhazes. Many of her works start with the painting of plastic sheets, which are then glued to a canvas. These plastic sheets are then peeled off of the canvas like a decal leaving behind paint. Some of these plastic sheets have been reused by Milhazes for as long as ten years. Often if a particular motif or drawing is well liked by the artist it will be kept, repainted, and added to multiple compositions. She describes these pieces of plastic affectionately, stating that they are imprinted with a memory, a memory that can cause irregularities. These irregularities are happily accepted by Milhazes as something that just comes with her process. In her works, Beatriz focuses on achieving a smooth surface as opposed to visible brush strokes with thickness being an intriguing topic but far from integral to her work and its importance. In this way she can play with the various sheen and levels of contrast that her materials provide in an attempt to further transform her canvas. In her own words Milhazes likens her process to the working-class, saying "I tell my friends that I'm like a bank worker...I come to the studio five days a week and do my job. I pay attention to detail, and try not to make mistakes."
Influence
Drawing Influence from the optical reactions provoked by artists like Bridget Riley and Tarsila do Amaral, Milhazes believes that art is an essential way for people to aestheticize an exteriorize their thoughts and feelings. Her work often serves as an exploration of the concept of conflict. Filled with intense colors and shapes, her work serves to inspire a strong dialogue as well as “challenging eye movements over easy beauty.” Milhazes also draws her influences from many other female artists such as Sonia Delaunay, Georgia O’Keefe, and Elizabeth Murray She has also cited the canon of Brazilian art history as “empowering in its celebration of women artists such as herself.”
Themes
Thematically, the work of Beatriz Milhazes has been described by one critic as "abstract, yet having something new to offer." This description is something that she believes draws people into her style, especially from a Western audience. Her work is known to contain many Brazilian folk references and can be interpreted as complex in this regard. These references, apparent in many of the vibrant colours and shapes, are often associated with the very poorest part of the population and are generally thought to be of little interest to the upper classes or intellectuals. These references have today changed in their meaning as the social elite has attached importance to them—the importance of being Brazilian and having Brazilian art. Finding the idea of a contradiction fascinating, it is another factor that influences the outcome of her art. Her installation Gamboa II, for instance, was strongly influenced by the carnival in her native country Brazil which includes dance, costumes and parades. These elements are evident in the work with its bright colours that also embraces a feminine style to the work.
