Red lead
Polarized photomicrograph of red lead at 500X. From the McCrone Paint Pigment Reference Set. Note appearance of blue-green interference colors. Due to small particle size, it is difficult to differentiate particles of red lead from that of other pigments with an optical microscope. Sample provided by the MFA Scientific Research Lab.
