The present invention is an infrared lamp manufactured by combining the components containing a copper compound (CuO, Cu (OH) 2 or Cu 2 O), aqueous methanol solution, concentrated sulfuric acid, silver nitrate (AgNO 3 ) aqueous solution, silicon dioxide (SiO 2 ) and loess coloring agent; A method for producing the colorant; And a coloring method using the coloring agent.n n n The present invention filters visible light of 700 nm or less, which causes eye fatigue and increases stress, and improves thermal effect by increasing infrared transmittance, and in particular, it is possible to provide a transparent black-red infrared lamp which is free from discoloration due to heat and chemicals. do.n n n n Colorant, coloring method, infrared lamp, filtering, heat effect |
