[0027] A method for preparing hollow transparent enamel jewelry, comprising the following steps:
[0028] 1) Structural optimization: Divide the hollow parts with ribs when making plates;
[0029] 2) Enamel glaze treatment: for the hollowed out parts with a diameter less than 5mm or a width less than 2.5mm, add carboxymethyl cellulose to the glaze to adjust the viscosity of the slurry;
[0030] 3) Place the false support: according to the placement direction of the enamel jewelry during firing, stick a foil on the bottom of the hollowed out position with a diameter of more than 5mm or a width of more than 2.5mm;
[0031] 4) Filling the enamel glaze: evenly fill the enamel glaze into the hollowed out part;
[0032] 5) Firing: The filled enamel jewelry is first fired at 790-810°C for 60-100 seconds, then the workpiece is taken out and covered with an aluminum silicate fiber tube preheated to 500-600°C, and cooled naturally;
[0033] 6) Grinding treatment: removing the foil bac...

[0042] Openwork transparent enamel dragonfly brooch (such as figure 1 Shown): The material is 18K gold, inlaid with diamonds and tourmalines, and the wings are fired with hollow transparent enamel. The length of the two wings of the dragonfly is about 80mm, and the width is about 17mm. The maximum width of the hollow is about 3.1mm.
[0043] Its production method is as follows:
[0044] 1) Structural optimization: The structure of the dragonfly is disassembled into three parts, two pairs of wings are one part, and the rest is one part. The wings of the dragonfly are hollowed out parts. During plate making, ribs with a thickness of 0.6mm are used to divide the wings into several areas. The division method is similar to the actual structure of dragonfly wings. The width of the frame where the wings directly contact with the enamel is controlled at 0.8-1mm;
[0045] 2) Place the false support: Paste a pure gold foil with a thickness of 0.07mm on the bottom of the hollowed out pa...

[0050] Hollow transparent enamel earrings (such as figure 2 Shown): The material is 930 silver alloy, the overall size of the earrings is about 50mm×20mm, and the maximum width of the hollowed out part is about 3.6mm.
[0051] Its production method is as follows:
[0052] 1) Structural optimization: Divide the hollowed-out parts with ribs with a thickness of 0.8mm during plate making, and control the width of the frame at 1.2-2mm;
[0053] 2) Place the false support: Paste a pure silver foil with a thickness of 0.1mm on the bottom of the hollowed out part. The outer dimension of the foil is 6mm larger than the hollowed out area. It will fall off. When pasting the foil, start from the middle of the hollowed out part, and use a brush, sponge and other tools to push the foil in turn to make it close to the bottom of the foil;
[0054] 3) Filling with enamel glaze: use wet glaze slurry, dip the glaze with a hook line pen to evenly fill the hollowed out parts of the wings, and e...
