The invention relates to a method for self-reduction imitation of Jun porcelain copper red glaze. CuO is taken as a colorant of copper red glaze, and metallic silicon is added into the glaze, so thatthe CuO can be reduced through the metallic silicon in high-temperature air to obtain the imitated Jun porcelain copper red glaze. By using the method, the CuO can be reduced without creating a reducing atmosphere, process steps can be reduced, raw material input can be saved, cost can be reduced, and the obtained imitation copper red glaze has wide application range; and the method has the characteristics of simple process and economy. 一种自还原仿制钧瓷铜红釉的方法，将CuO作为铜红釉的着色剂，并且向釉料中加入金属硅，在高温空气中即可通过金属硅还原CuO，得到仿制的钧瓷铜红釉；使用本发明无需营造还原性氛围即可对CuO进行还原，能够减少工艺步骤，节约原料投入，降低成本，并且得到的仿制铜红釉应用范围广泛；本发明具有工艺简单和经济节约的特点。
