[0014] Example 1 Preparation of colored glaze of the present invention (1)
[0015] 1) Weigh each raw material: 99 parts of quartz sand, 45 parts of soda ash, 10 parts of aluminum oxide, 49 parts of lead dioxide, 1 part of cerium oxide, 3.5 parts of antimony trioxide, 0.4 parts of sodium nitrate, Cr 2 O 3 0.6 part, 0.6 part of CuO, evenly mixed;
[0016] 2) Melt the raw materials in a kiln at a melting temperature of 1630°C, a clarification temperature of 1680°C, a melting time of 13 hours, and a clarification time of 6 hours to obtain molten glass;
[0017] 3) Cool the molten glass to 1100°C, and perform artificial shaping according to the designed shape. The artificial shaping is specifically: manual picking, using scissors, handles, blowpipes, molds and other tools to manually blow, pull, press, and rotate , Squeeze and other processes to make colored glaze into the desired shape;
[0018] 4) The formed product is sent to the annealing kiln for annealing, the annealing temperature...
