Hereinafter, a method of manufacturing accessories for jewelry according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a flow chart showing a manufacturing process of the accessories for jewelry of the present invention, Figure 2 is a view showing a manufacturing process of one embodiment of the present invention.

First stage

If the material 10 of the decorative part is a leaf or petal with many wrinkles on the back, apply liquid wax 21 on the petal to an appropriate thickness to solidify it at room temperature, and shape the upper surface into a petal to wax. The model 20 was made.

2nd step

On the wax model 20 separated from the petal, a hot waxing and protruding protrusion 20a was attached.

3rd step

The wax model 20 with the prongs and projections 20a attached thereto was buried in gel-like gypsum, coated with gypsum, taken out, and naturally dried at room temperature for about 45 minutes to 2 hours to form a plaster molding 30.

At this time, the protrusion 20a is to be immersed in the gypsum gypsum to the extent proportional to the thickness coated on the wax model 20 and the remaining portion is exposed to the outside, but may not protrude to the outside.

In addition, the protrusion 20a may be used as wood to be removed by burning together with wax when firing gypsum in the following process.

4th step

The dried gypsum molding is put into a heating furnace and calcined to burn and wax the wax model 20 which is buried. Thus, a cavity 41 having a wax model 20 form is formed therein, and at the same time, the protrusion 20a is present. On the site, a gypsum mold 40 was formed in which a spout 42 connecting the cavity and the outside was formed.

5th step

The molten state of gold was injected into the inner cavity 41 of the plaster mold 40 from which the wax model was removed, and then, the mold was cast in a circular shape by cooling for about 30 minutes at room temperature. As the molten metal, silver, aluminum, platinum or the like can also be used.

6th step

The cast gypsum mold 40 is completed by crushing to demould the decorative member 51 prototype, and finished as needed to prepare a decorative member 51. At this time, the part corresponding to the circular protrusion 20a of the decorative member 51 can be removed or it can be lifted as it is.

The decorative member 51 manufactured in this way was attached to the projection body (50a) part or other parts to the jewelry body 50 to make ornaments.

On the other hand, when demolding the mold 40 is preferably crushed in a state of immersed in cooling water, this is because the water in the gypsum in addition to the point that the heat does not cool completely because only the 30 minutes to cool the plaster mold in the fifth step This is because when submerged, it is easily crushed and the crushing time is shortened.

Figure 3 is a view showing a modified embodiment of the embodiment of Figure 2 applied to the present invention the fuzz production of amorphous gems.

In FIG. 3, except that the material of the accessory for jewelry is an amorphous gem 10, a jewelry fuzz for the jewelry part 20 is manufactured in the same process as in FIG.
