Encaustic,
Tablet size 60cm x 60cm x 5cm
Hang as a "tablet" - no frame or glass necessary.
Hot encaustic wax is a medium, used in ancient Egypt and Rome. These collages are embedded in this amazing lustrous medium, enabling them to be presented without glass, hung as a "tablet" directly onto the wall.
Do not hang above a radiator or in full sun. Buff with a soft cloth every month or so, to retain the sheen.
