El Ocote is an archaeological site located in the state of Aguascalientes, in the upper part of the Cerro de los Tecuanes. Thanks to recent research by the National Institute of Anthropology and History (INAH), several cultural remains have been found belonging to sedentary groups of the Epiclassic (650–900 AD) before the Chichimecs, who practiced agriculture, hunting, fishing and pottery. These groups developed diverse artifacts, such as vessels, figurines and bowls for common or ceremonial use, which have diverse features and pigmentations with colors such as Red/Cream, Cream, Red/Black, Polished Orange, Polished Red, Polished Brown, Red, Polished Brown/Black and Black. These ceramics have been little studied and are the object of the present archaeomagnetic study to determine their composite minerals by means of experiments investigating the magnetism of the rocks, their archaeomagnetic intensity, as well as their color on both sides to get a selection criterion for color in the attainment of the intensity, besides estimating their age from the paleosecular variation curves of the intensity. Among the nine ceramic samples studied, six were accepted due to their thermomagnetic stability, with a predominant presence of titanomagnetites with high and low titanium content. It was possible to successfully determine four intensities and estimate their associated ages, which corresponded to the Epiclassic. Correlations were found between color parameters with remanence coercivity, saturation magnetization and ratios derived from hysteresis curves.
