The invention relates to a production method of daily ceramic, in particular to a production technological method of a sepiolite nanofiber-reinforced shell ceramic billet. The sepiolite nanofiber-reinforced shell ceramic billet is prepared from the following raw materials in parts by weight: 35 to 55 parts of shell powder, 10 to 20 parts of feldspar powder, 5 to 15 parts of quartz powder, 25 to 45 parts of clay and 5 to 10 parts of sepiolite nanofiber. The sepiolite nanofiber-reinforced shell ceramic product prepared through the method is high in thermal shock resistance, and the breaking strength is improved by 20 percent or above; and moreover, the molding rate is increased, the billet density is increased, defects of deformation, cracking and the like are reduced, and the cost is lowered.
