Auric Field, Aqua Mint (large) belongs to Baker's Auric Field series, works made by listening to sound frequencies in a meditative state and painting the energy they generate, then hand-embellishing the canvas with diamond dust so the aura shimmers at the edge of seeing. The aura, she writes, is the electromagnetic energy field that is the bridge between our spiritual and physical body, and each colourway carries its own frequency. This one speaks in aquamarine and blue jade: the tones of aquamarine are associated in spiritual realms with cleansing energy, and, as with the waves of the ocean, with trusting and letting go; the shades of blue jade are represented as a talisman of peace, restoring equilibrium to the observer. The material carries the meaning. Diamond dust hand-applied across the fine canvas turns the painted aura into a field of light that shifts as the viewer moves, so the work behaves like the thing it depicts: an energy field, felt rather than fixed. At 100 x 100 cm, the large format gives the aura room to breathe, the gradient opening from its bright centre toward the frame's edges like light through water, a body of water rather than a talisman, scale giving the cleansing colours room to work on a whole wall. Ink with hand-embellished diamond dust on fine canvas, in a box tray frame. 100 x 100 cm unframed; 105.5 x 105.5 x 4 cm framed. Signed and numbered from an edition of 6, plus 1 artist's proof. £4,500.
