[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The present invention provides a method for producing a cremains craftwork, which has good stability, thermal stability and chemical stability, solves the problems of environmental damage and the like in the existing methods of commemorating the deceased, and produces cremains craftwork with stable material properties and long-term preservation through specific processes and raw material formulas. DETAILED DESCRIPTION

[0025] The preferred embodiments of the present invention are described below. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0026] Example 1

[0027] The present invention provides a method for making a cremation craft, wherein the raw materials are selected from:

[0028] 1. Pure human ashes are the main ingredients, which are the main source of ashes crafts and carry the commemorative significance of the deceased.

[0029] 2. Select crystal powder, gold powder, and thuja powder as auxiliary agents. Crystal powder can increase the transparency and glossiness of the product, gold powder can give the product a certain metallic texture and decorativeness, and thuja powder may bring a special smell or texture effect to the product during the firing process.

[0030] Ashes Disposal:

[0031] 1. Take pure human ashes and put them into clean water, stirring them thoroughly to disperse the ashes.

[0032] 2. Filter out large pieces of human ashes impurities through natural sedimentation or using a filtering device to obtain pure human ashes fine powder that sinks in water. Natural sedimentation uses the difference in the size and density of bone ash particles to separate larger particles of impurities by settling at the bottom; the filtering device can be a conventional filtering device such as a filter screen or filter paper, which can remove impurities more efficiently.

[0033] 3. Evaporate the bone ash powder containing water to obtain pure and dry 100-200 mesh bone ash powder. The drying method can be conventional heating to evaporate water, such as using an oven and other equipment, controlling the temperature and time to ensure that the water is completely evaporated and the bone ash powder is not destroyed. The particle size range of 100-200 mesh is conducive to the subsequent uniform mixing with additives and molding operations.

[0034] Hybrid molding:

[0035] 1. Take the processed pure dry bone ash powder and 100-200 mesh crystal powder, gold powder, and thuja powder in a ratio of 1:0.2-0.8, put them into a blender or other equipment and mix them thoroughly to ensure that all ingredients are evenly distributed.

[0036] 2. Then add water to the mixture at a ratio of 1:0.1-0.4 and stir evenly to make the material have a certain plasticity. The amount of water added must be strictly controlled. Too little water will make the material difficult to shape, and too much water will make the semi-finished product structure unstable after shaping.

[0037] 3. Use mold pressing or hand kneading to make the mixed materials into semi-finished products. The mold can be in various shapes, such as rings, discs, hearts, etc., to meet the needs of different consumers for the shape of ash crafts. Mold pressing can ensure the consistency and regularity of the product shape, while hand kneading can give the product a certain sense of handmade art.

[0038] Powder coating:

[0039] Put the semi-finished product into 100-200 mesh crystal powder to coat it with a layer of crystal powder. This can not only further enhance the beauty of the product, making the surface of the ash crafts crystal clear, but also protect the internal structure to a certain extent.

[0040] Drying treatment:

[0041] Place the semi-finished product after coating in a 50-100 degree environment to dry for 1.5-3 hours, or place it in a cool place to air dry for 24 hours. Control of the drying environment temperature and time is crucial to the drying effect and quality of the semi-finished product. Higher temperature can accelerate the evaporation of water, but too high temperature may cause problems such as product cracking; natural air drying takes a long time but can make the product dry slowly and evenly, reducing the internal stress caused by rapid drying.

[0042] Preheating treatment:

[0043] Preheat the dried semi-finished product at 200℃-900℃ for 3-5 hours. The purpose of preheating is to stabilize the internal structure of the product initially, prepare for the subsequent high-temperature firing, reduce defects such as cracks caused by rapid temperature changes during the firing process, and help the additives and bone ash powder to better fuse and react.

[0044] Firing treatment:

[0045] The firing process is carried out in stages. First, it is heated at 600℃ to 1200℃ for 1-2 hours. At this stage, the product can be initially sintered and some components begin to undergo physical and chemical changes, such as the crystallization of inorganic substances in the ashes. Then it is heated at 1200℃ to 1400℃ for 1-2 hours to further improve the density and strength of the product and make the product structure more stable. Finally, it is heated at 1600℃ for 1-2 hours. At this high temperature stage, the physical and chemical properties of the product reach the final state, and the various components are fully integrated and reacted to form a stable structure of ashes crafts. The heating temperature and time of each stage can be fine-tuned within a given range according to actual needs to obtain finished ashes crafts of different colors, textures and textures to meet diverse market needs.

[0046] Cooling treatment:

[0047] The cooling process is also controlled in stages. Cooling at 1600℃-1000℃ for 1 hour. Rapid cooling at this stage can make the product surface solidify quickly, forming a certain hardness and gloss; cooling at 1000℃-100℃ for 2 hours, slowly cooling the internal structure, reducing the internal stress caused by rapid temperature changes, and preventing product cracking. The cooling speed can be adjusted by controlling the ambient temperature, ventilation conditions or using auxiliary cooling equipment (such as cooling fans, etc.) to ensure the quality of the finished ash crafts.
