The series Issu du feu corresponds to an essential moment in the artist's career, his arrival in Paris and the discovery of a new material that marks a turning point in his method: wood charcoal. Wood charcoal allows him to combine and bring together two subjects, matter and black. Charcoal’s blackness becomes a source of color that encompasses all others, which itself come from the fire.
For Lee Bae, "Charcoal is the last material remaining when all others are dead, so it is always a potential genereator of energy. When all is gone, the purity of its matter remains ». The artist plays on its "physicality" and awakens its existential dimension. What is issued from fire is ultimately a vital material, a potential form, following the idea that « asian culture loves to master the mind and sets great importance by spirituality ».
