During more than a year, Perla Krauze (Mexico City, 1953) developed an inquiry of the local materials of the state of Puebla, carrying out several tours to explore multiple approaches to the production of a State with a wealth of natural resources. Krauze chose to work with the earth and its processes. To do so, she began an intensive analysis made possible and accompanied by the producers, carvers, and workers of the diverse stone elements.

Continuous visits to workshops in Tecali and San Salvador el Seco, quarries in Nealtican and Tlayúa, brick factories in Huejotzingo and Cholula, fossil deposits in San Juan Raya and Tepexi de Rodríguez, as well as clay producers from Los Reyes Metzontla, spring in Tehuacán, salt mines in Zapotitlán and the Tehuacán-Cuicatlán Biosphere Reserve, among others, revealed to the artist the strong and meaningful relationship between the locals, and the earth and its elements, defining not only the physical environment, but also their socio-cultural reality. These inhabitants preserve among their most precios belongings, unusual stones found during their labors.

The numerous forms of presentation, organization and classification of stones used by he local workshops implemented a bridge with previous works of the artist. Different forms of stacking, organizing and cataloguing materials created a dialogue with Krauze and the bond she establishes with these elements in her atelier.

Thus, through multiple approximations, Perla Krauze proposes an approach to the lithic components of Puebla, to their most primitive characteristics and cultural consequences, reading it as the result of long and complex geological processes, transforming it into a container of a memory that integrates traces of diverse contexts and forms of life that have pervaded the surrounding communities.
