Problems solved by technology

However, the output of natural chalcedony, especially yellow chalcedony, is limited, and most of the produced chalcedony is mainly white chalcedony with a gray tone. Its texture is poor, often contains impurities, and its color is uneven.
There is no relevant modern information on the optimal processing method of chalcedony, and the optimal processing technology of jade with similar chemical composition such as agate is relatively scarce, while the technical information of agate is relatively scarce, and the technical details have not been disclosed

Embodiment Construction

[0016] In order to make the technical problems, technical solutions and advantages to which the present invention to be solved is more clear, and the specific embodiments will be described in connection with the specific embodiments.

[0017] The present invention provides a method of optimizing the preparation of gray-white jacadial oxelling.

[0018] The method includes the steps as follows:

[0019] (1) Place the gray-white moort stone in a beaker containing an acidic solution, so that the gray-white orthodontic stone is fully immersed in solution;

[0020] (2) Putting steps (1) in a gray white grade stone soaked at room temperature for no less than 8 days, then heating and soaking;

[0021] (3) Place the gray white grade stone after soaking in the aluminum oxide plate is placed in the muffle furnace;

[0022] (4) Gray white octrine temperature rises to 250 ° C in the muffle furnace, maintaining this temperature for 4 hours;

[0023] (5) After the heating is completed, the muff...

Abstract

The invention provides a method for preparing yellow jade marrow by optimizing grey jade marrow, and belongs to the technical field of gemstone processing. The method comprises the following steps of: heating and soaking a grey jade marrow raw material in an acid solution; taking out the grey jade marrow raw material and putting the same into a muffle furnace, heating the material at normal pressure and performing heat preservation; after finishing the treatment, naturally cooling the muffle furnace to room temperature; and obtaining yellow jade marrow. According to the method, a mode of carrying out thermal optimization treatment on the grey marrow in the ferric chloride and concentrated hydrochloric acid solution environment is adopted, on one hand, concentrated hydrochloric acid can inhibit ferric chloride from becoming ferric hydroxide and can also corrode impurities in the ferric chloride; and on the other hand, heating and soaking can accelerate the speed of iron ions entering the crystal, so that the jade marrow presents a more uniform yellow effect, and the yellow jade marrow with pure texture and uniform color is produced.

Description

Technical field [0001] The present invention relates to the field of gem processing, in particular to a method of optimizing the preparation of gray-white jacadic oxma. Background technique [0002] The jade marrow is a natural jewelry that is popular with people, the color is an important factor in evaluating the value of 髓. The aorta belongs to the crystalline collection of jade, and its structure is relatively dense, resulting in a very difficult color improvement. As the domestic jewelry market is increasing to increase the heat of crystalline quartz jade, high quality jade marrow will become inquiishing. Natural jams, especially the yield of Huang Yu, and most of the oysters are mainly white with gray-tuned white jet, and their texture is poor, often contain impurities, and uneven color. The optimization method of the aorta has no related modern data. Jands such as agate similar to their chemical composition is relatively lacking, and agate's technical data is relatively sma...
