In addition to tapestry, the artist has made inroads in painting, engraving and ceramics. In order to create her works, she utilizes a mix of elements of
land art,
abstract expressionism, and
pop art. Some of her works reflect her interest in the
cave paintings of
Baja California. In her tapestries, she uses natural Mexican fibers, and in some of her paintings she uses native
Amate paper from Mexico. In incorporating materials such as wire, cord, and fiber into her weaving, Palau and others such as
Olga de Amaral,
Myra Landau, and
Feliciano Béjar, have created "a highly original form of aesthetic expression" specific to Latin America. The exploration of tapestries serves an important role in her work. After having developed her techniques in engraving, during the 1970s she began to work with weavings, initially beginning with the
serape. According to Raquel Tibol, in those years many artists were interested in weaving, which incited Palau Bosch to travel to Barcelona where she met Grau Garriga and assimilated his style. Her reevaluation of tapestry as a medium led to a reconsideration of the division between the artist and the artisan: when the former returns to a technique relegated to the "lower arts", they recover their status as a manual worker. For Tibol, the value of the artist's works woven with
henequen, wool or synthetic yarns align them more with the world of sculpture. However, she uses her works to develop ideas around specific themes, such as the critique of censorship and repression of the Franco dictatorship in
Los Sellos de la España Sellada ('The Stamps of Stamped Spain') in 1976. In 1970, the artist participated for the second time in the Salon Independiente, exhibiting
Ambientación Alquímica ('Alchemical Atmosphere'), one of her most well known pieces that currently forms part of the standing collection of the
Museo Universitario Arte Contemporáneo. It is an open, walk-in structure with movable wooden wall panels and geometric forms made from carton and newsprint, with numbers and syllables painted on it that form the word
Tetragramaton. While inside it, the spectator becomes an active and ludic element in the work itself, a concept that had barely begun to be explored in that time. "a talisman of strength and protection, in which the public participates, because part of the joke is that you have to enter, and upon doing so, the doors revolve and the same image appears over and over: a triangle based in alchemy, in the name of God that should not be spoken, Yahweh, that is divided into 4 letters, that is 4 syllables" (translation)Her later works consist of installations and tapestries made with natural materials such as coco fibers and dyed corn husks. The ensemble of pieces titled
Mis caminos son Terrestres ('My Roads are Lands') has been interpreted by as approaching an identity somewhere between the structure of myth and art. In her installation
Nomadas II, Palau plays with the dimensions of a series of sizes of disembodied outstretched feet, referencing cave paintings made by early humans found in the rockshelters of Baja California. In
Doble Muro, the artist comments on the issue of undocumented immigrants and the proposed border wall between the United States and Mexico, by creating a structure of two walls on a base of wooden columns. Inside, on the floor of the structure is the outline of a human body woven with fibers, surrounded by the 2 symbolical walls, evoking the chalk silhouettes made by police or medical personnel to demarcate the position of a cadaver on the ground. == Themes on the subject of women ==
