The invention discloses a use method of luminous attapulgite soft ceramic powder. The technical scheme comprises the following main points of: placing the attapulgite soft ceramic powder into a vessel; slowly adding hot water into the attapulgite soft ceramic powder; timely stirring and kneading the attapulgite soft ceramic powder into a strip-shaped clod; coating methyl silicone oil on the outersurface of the strip-shaped clod to knead again; and pressing the strip-shaped clod into soft attapulgite clay. The attapulgite soft ceramic powder comprises purified attapulgite, swell soil, sepiolite, calcium chloride, polyacrylate sodium, sodium carboxymethyl cellulose and sodium stearoyl lactylate. The soft attapulgite clay prepared by the attapulgite soft ceramic powder, water and the methylsilicone oil has the characteristics of high viscosity, good soft plasticity, low shrinkage rate and no deformation, is hardened after being naturally dried, does not need to be roasted, does not generate cracks, does not mold, degenerate and affect the skin, is nontoxic and noncorrosive and does not have greasy feel. The use method of the attapulgite soft ceramic powder is suitable for adopting the attapulgite soft ceramic powder to prepare the soft attapulgite clay on site.
