His art is clearly contemplative in nature. Mlącki paints on canvas, timber boards, cork sheets. He makes sculpted objects using a string, or makes spatial, illusive painting objects. The array of colours is much limited: various shades of white, grey, black, brown. The artist oscillates on the borderline of minimalist geometric abstract art and object-depicting art.
Turning paints into colours, colours into light, light into space, and space into a meaning, is an incessant desire to achieve a harmony of consonance, a perfect form, as Mlącki himself puts it. Objects which can be found in his paintings are strongly meaningful: candles, envelopes, windows, doors, mirrors. However, the artist does not set the process of symbolizing in motion. His symbols are resting ones, and thus they provoke the viewer to be taken up on his or her own, and follow up mentally in an unknown direction.
