[0020] (1) prepare following golden spraying liquid raw material by weight percentage: tetrachloroauric acid 0.2%, copper nitrate 6.8%, bismuth nitrate 2.0%, titanium tetrachloride 2.0%, rosin resin 15%, 200# solvent naphtha 21%, turpentine 53%;
[0021] (2) First heat the rosin resin to 150°C, and keep it at a constant temperature for 5 hours to melt it, then add copper nitrate, bismuth nitrate, and titanium tetrachloride in sequence, and keep the temperature for 2 hours after the reactant turns into a brown-black paste. Hours later, slowly add tetrachloroauric acid, stir and homogenize for 2 hours, cool down to 100°C, add 200# solvent oil and turpentine in turn, stir at constant temperature for 2 hours, and finally make a golden spray liquid for use;
[0022] (3) Prepare the following glass-ceramic raw materials by weight percentage: 50% of quartz sand, 1.63% of aluminum oxide, 6.7% of calcite, 5.91% of sodium fluorosilicate, 17.8% of borax pentahydrate, 6.09% of boric acid,...
