Nanocrystals are the determinants of the red color of the glaze. The CuO reduction reaction temperature range of SiC produces a reducing environment in the glaze as detected by the method (DSC). The functional group and phase of nanocrystals were determined by Fourier transform infrared (FT-IR) and X-ray diffraction (XRD) spectroscopy.</span></span><span style="background-color:#ffffff;">&nbsp;</span> </span></span></span></span></span></div> CuO,SiC,nanocrystal,in situ reducing agent 1 9 http://ijmse.iust.ac.ir/browse.php?a_code=A-10-4833-1&slc_lang=en&sid=1 Nguyen Vu Uyen Nhi nvunhi@hcmut.edu.vn 1800319475328460017305 1800319475328460017305 No Ho Chi Minh City University of Technology (HCMUT) Doan Duong Xuan Thuy thuy.doanbachkhoa@hcmut.edu.vn 1800319475328460017306 1800319475328460017306 No Ho Chi Minh City University of Technology (HCMUT) Do Quang Minh mnh_doquang@hcmut.edu.vn 1800319475328460017307 1800319475328460017307 No Ho Chi Minh City University of Technology (HCMUT) Kieu Do Trung Kien kieudotrungkien@hcmut.edu.vn 1800319475328460017308 1800319475328460017308 Yes Ho Chi Minh City University of Technology (HCMUT),
