Materia Contenida N1 Original artwork · Unique piece Technique: Mixed media Support: Cotton canvas Dimensions: 80 × 60 cm · depth 2 cm Description — English Materia Contenida is an abstract artwork dominated by deep black tones, subtly contrasted with a soft brick-brown hue that emerges within the composition. The work is structured around two distinct planes: a stable upper field of dark, restrained calm, and a lower band where matter accumulates in a dense, almost sedimentary form. This warmer brown presence introduces a quiet chromatic tension, grounding the piece while remaining fully contained. The upper surface remains in apparent stillness, crossed by subtle, circular gestures that do not seek rupture or impact, but rather balance and permanence. Matter does not expand or release itself; it remains held and restrained, generating a silent tension that permeates the entire artwork. The piece explores containment as both a physical and emotional state. There is no violence or explosion, only control, resistance, and depth. Matter is presented as a living element, charged with latent energy, deliberately contained to prevent overflow. The dialogue between black and soft brick-brown tones, combined with layered textures, transforms the surface into a space of reflection on limits, weight, and silence. Depending on the incidence of light, the protective finish produces subtle reflections that reveal hidden nuances and reliefs, adding depth and visual variation without altering the sober and restrained character of the artwork.
