Mina has always set technical challenges for herself in the hope of discovering some new angle. Technical confidence and an open mind, receptive to inspiration – sometimes from unexpected sources – can combine to produce surprising results which, once she recognises their potential, can then be incorporated into the work.
Aleatoric music (also aleatory music or chance music; from the Latin word alea, meaning "dice') is music in which some element of the composition is left to chance, and/or some primary element of a composed work's realization is left to the determination of its performer(s).
Beginning with a very precise rectilinear piece of 18ct yellow gold, small rectangles of gold or platinum are soldered to it in a random arrangement. Predetermined cuts are then made in straight lines with a fine sawblade from the edges of the rectangle, inwards to the small pieces.
Repeated rolling presses the small rectangles into the surface of the background while displacing the metal in an uncontrolled way and creating an unpredictable, lively outline. A textured surface is added during the final rolling.
No metal is removed, apart from the necessary smoothing of all the edges, which are then burnished with a steel tool. Textured platinum mounts are sometimes soldered in place for pave setting, if small diamonds are to be incorporated.
