Mandell's talent lies in the implementation of fundamental fine art concerns such as perspective, color composition and drawing into the medium of mosaic. Utilizing such materials as glass shards, ceramic tile, semiprecious stones, minerals, mirror, marbles, Mandell creates wall mounted panels which evolve into tactile paintings. His grout lines act as drawing lines, bringing his imagery to life. The glass shards are not flat, but rather are convex and concave pieces. This allows for a study of the surface topography of the mosaic.. In addition to his wall mounted mosaics, Jonathan has a wide portfolio of sculpture mosaics.
