Kline tends to work a lot with encaustic, pigmented wax that can be applied in layers. This allows more of a transparency than do oils, and Kline’s use of encaustic will add a dimensionality to his paintings that simply would not be there with oils or acrylics. He chooses also stainless steel and cast bronze as trademark tools for a major part of his recent projects. Oath is encaustic on wood, Wounded Healer stainless steel, and Night Time Enigma encaustic on panel.
