“…Figure 3 repeats the same experiment utilizing a range of Au:Ag glaze mixtures for tiles fired in a reductive environment, with results showing a striking difference in the vibrancy of the color produced. In the reduction-fired samples, the 100:0 glaze mixture ( Figure 3 A—far left) creates a deep red color, consistent with previous reports employing Au-NPs in ceramic glazes [ 5 , 22 ]. The majority Au ratios (i.e., 80:20 and 60:40) maintain this general shade of red as well, but act as a brightener, yielding a more desirable red than just the pure Au-NP sample.…”

“…The study was initiated by preparing standard ceramic glaze mixtures doped with different ratios of HAuCl 4 and AgNO 3 salts, traditional precursor salts used to form NPs in solution [ 4 , 5 ]. The salt ratios of HAuCl 4 and AgNO 3 (Au:Ag) incorporated in the glaze formulations included the following: 100:0 (100% Au), 80:20, 60:40, 40:60, 20:80, and 0:100 (100% Ag).…”

“…[1][2][3][4] Many researchers have prepared gold nanoparticles with different color rendering effects (such as dark purple, pink, violet, and red) and have applied them in the ceramic industry. [5][6][7][8] However, a strong limitation to gold nanoparticles stems from their high cost and low stability at or above 800 • C. In order to improve the high-temperature stability of gold nanoparticles, some studies reported that gold nanoparticles were wrapped in aluminum, silicon, and tin, in which the temperature for the stability of the pigments could be increased to 1200 • C. 7,[9][10][11] Nevertheless, it also caused the reduction or deviation of the coloring effect of the pigment. In the field of ceramic pigments, there are even decoration techniques similar to underglaze pigments, and the processing temperature is usually required to be 1200 • C or above.…”
