PURPOSE: Provided is a general-purpose plastic containing yellow ocher, that is a compound chip containing up to 20wt% of yellow ocher having a far infrared emissivity of 91%, has an excellent antibacterial deodorization function, and can reveal ocher and the color of Korean pottery without an artificial pigment. CONSTITUTION: The plastic containing yellow ocher is obtained by the steps of: i)mixing and dissolving 5-20wt% of ocher fine particles having an average particle size of 1-3micrometer, 2-3wt% of a coupling agent(methacylate silane), 0.5wt% of butyl stearylate and 10wt% of plastic power to a general thermoplastic resin chip as a main component; ii)anastomosing the mixture on the plastic chip while yellow ocher and an additive are jetted by a spray in a high-speed agitator; iii)extruding it through a hopper at an extruder at 170-200°C, followed by cooling it in a cooling bath; and then iv)cutting and drying.
