1. A powder for molding for obtaining a ceramic object by heating by means of irradiation with a laser light, the powder comprising a plurality of compositions,
wherein at least one composition of the plurality of compositions is an absorber that has a stronger capability to absorb a light having a predetermined wavelength included in the laser light than other compositions of the plurality of compositions, and changes to a different composition that more weakly absorbs the light having the predetermined wavelength than the absorber by irradiation with the light having the predetermined wavelength,
wherein a content of the absorber is 0.5 vol % to 53 vol %, and
wherein the absorber forms a particle as a single compound and a particle diameter of the particle forming the absorber is 10 μm or less.
