Since early the Pre-Hispanic age, the Peoples who settled in the Mexican territory have been known for being experts in working with a wide variety of clays, sands, and soils, mixing them with water, and creating magnificent pieces. As time went by, Mesoamerican techniques for working with clay, such as Pastillaje, Bruñido, and Esgrafiado (Pastillage, Burnished, and Sgraffito) were perfected until they have now reached their best expressions in places such as Dolores Hidalgo, Guanajuato, and Tonalá, Jalisco.
