Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of ceramic processing, and particularly relates to a ceramic snow glaze formula and a firing process method. BACKGROUND

[0002] As a treasure of human civilization, ceramic art has a long history and exquisite skills. In the process of decoration and production of ceramics, the selection of glaze and the firing process are crucial. Although traditional ceramic glazes and firing methods can produce a variety of ceramic works, they still have limitations in certain specific effects, such as simulating natural snow scenes and snow mountain landscapes.

[0003] Existing ceramic glaze formulas often cannot simultaneously meet the requirements of high whiteness, high transparency, and good melting performance. In particular, when making ceramic works with snow mountain effects, traditional glazes often cannot form delicate and natural snowflake textures, and the color is single and lacks levels. SUMMARY

[0004] The purpose of the present application is to provide a ceramic snow glaze formula and a firing process method to solve the problems raised in the background.

[0005] To achieve the above purpose, the present application provides the following technical solutions:

[0006] A ceramic snow glaze formula includes the following percentage of raw materials: 15-20% of aluminum oxide, 60-70% of silicon dioxide, 5-8% of ferric oxide, 5-10% of potassium oxide, and 3-5% of sodium oxide.

[0007] Preferably, the following percentage of raw materials is included: 20% of aluminum oxide, 60% of silicon dioxide, 5% of ferric oxide, 10% of potassium oxide, and 5% of sodium oxide.

[0008] Preferably, the following percentage of raw materials is included: 15% of aluminum oxide, 70% of silicon dioxide, 7% of ferric oxide, 5% of potassium oxide, and 3% of sodium oxide.

[0009] A firing process method for a ceramic snow glaze formula includes the following steps:

[0010] S1, raw material pretreatment: calcine the raw materials at 300 degrees to remove water, organic matter, and volatile impurities therein;

[0011] S2, glaze preparation: grind the calcined raw materials into powder, grind to the standard of passing through a 200-mesh screen, and mix the various powdered raw materials uniformly according to the following percentage of raw materials: 20% of aluminum oxide, 60% of silicon dioxide, 5% of ferric oxide, 8% of potassium oxide, and 7% of sodium oxide.

[0012] S3, glazing: evenly spread the prepared glaze powder on the surface of the ceramic work, with a thickness of 0.4-0.8mm, forming a certain thickness of glaze layer, and the powder spreading process should be carried out in a relatively dry and dust-free environment to avoid glaze dampness or pollution.

[0013] S4, drying: after glazing, the ceramic work is placed in a dry and ventilated place for natural drying or low-temperature drying to accelerate the drying process;

[0014] S5, high-temperature firing: the dried ceramic work is placed in the kiln for high-temperature firing, and the heating process should be slow to avoid cracks or deformation of the ceramic work due to thermal expansion and contraction;

[0015] S6, heat preservation treatment: when the temperature of the kiln reaches 1250-1300℃, the heat preservation treatment is carried out for 2-4 hours;

[0016] S7, cooling: after the heat preservation is over, the temperature of the kiln should be slowly reduced to room temperature, and then taken out;

[0017] S8, quality inspection: quality inspection is carried out on the fired ceramic snow glaze work.

[0018] Compared with the prior art, the beneficial effects of the present application are:

[0019] By precisely controlling the proportions of aluminum oxide, silicon dioxide, ferric oxide, potassium oxide and sodium oxide in the formula, and optimizing the firing process, the present patent successfully realizes the unique snow mountain effect of ceramic snow glaze. The glaze surface is smooth and delicate, the color is uniform and has a sense of hierarchy, greatly improving the artistic value and ornamental value of the ceramic work. At the same time, the addition of aluminum oxide in the formula significantly improves the hardness and wear resistance of the ceramic, making the ceramic snow glaze work more durable and less likely to be scratched or damaged during use. At the same time, the optimized firing process ensures the stability of the ceramic structure, reducing the risk of cracks or deformation due to thermal expansion and contraction.

[0021] Embodiment one:

[0022] A ceramic snow glaze formula, including the following percentage ingredients: 20% aluminum oxide, 60% silicon dioxide, 5% iron trioxide, 8% potassium oxide, and 7% sodium oxide.

[0023] A firing process method of a ceramic snow glaze formula,

[0024] 1. Raw material pretreatment

[0025] Calcination: The raw materials are calcined at 300 degrees to remove water, organic matter and volatile impurities, improve the purity and stability of the raw materials. This step is crucial to ensure the uniformity and fluidity of the subsequent glaze.

[0026] 2. Glaze preparation

[0027] Grinding: The calcined raw materials are ground into powder, ground to pass through a 200 mesh screen, ensuring fine and uniform particles. This helps to form fine texture and uniform color during firing.

[0028] Mixing: Mix the various powdered raw materials according to the formula ratio, the raw material ratio is 20% aluminum oxide, 60% silicon dioxide, 5% iron trioxide, 8% potassium oxide and 7% sodium oxide.

[0029] 3. Glazing

[0030] Uniform powdering: The prepared glaze powder is evenly spread on the surface of the ceramic work to form a certain thickness of glaze layer. The thickness is 0.4mm, and the thickness and uniformity of the glaze during the spreading process should be controlled to avoid cracks or deformation during firing.

[0031] Drying: After glazing, the ceramic work is placed in a dry and ventilated place for natural drying. The purpose of drying is to remove the water in the glaze, and to prepare for the subsequent firing.

[0032] 4. High temperature firing

[0033] Temperature control: The dried ceramic work is placed in the kiln for high temperature firing. The temperature should be raised slowly and uniformly to avoid cracks or deformation of the ceramic work due to thermal expansion and contraction.

[0034] Soaking treatment: When the temperature of the kiln reaches the set firing temperature, a certain period of soaking treatment is needed. The length of the soaking time depends on the size, shape of the ceramic work and the performance of the glaze. The purpose of soaking is to make the glaze fully melt and flow, forming fine texture and uniform color.

[0035] Cooling Down: After the soaking period, the kiln temperature should be slowly reduced to room temperature. The cooling rate should also be controlled within a reasonable range to avoid cracks or deformation due to thermal expansion and contraction.

[0036] 5. Post-Processing

[0037] Quality Inspection: Finally, the fired ceramic snow-glazed works are inspected for quality to ensure they meet the desired snow mountain effect and other performance requirements.

[0042] 2. Glaze Preparation

[0043] Grinding: The calcined raw materials are ground into a powder to ensure fine and uniform particles. This helps to form a delicate texture and uniform color during the firing process.

[0047] Drying: After glazing, the ceramic work is placed in a low-temperature drying oven to accelerate the drying process. The purpose of drying is to remove moisture from the glaze, preparing for subsequent firing.

[0048] 4. High-Temperature Firing

[0049] Temperature Control: The dried ceramic work is placed in a kiln for high-temperature firing. The temperature rise should be slow and uniform to avoid cracks or deformation due to thermal expansion and contraction.

[0050] Soaking: After the kiln temperature reaches the set firing temperature, a period of soaking is required. The length of soaking time depends on the size, shape of the ceramic piece, and the properties of the glaze, among other factors. The purpose of soaking is to allow the glaze to fully melt and flow, resulting in a fine texture and uniform color.

[0051] Cooling: After soaking is complete, the kiln temperature should be slowly reduced to room temperature. The cooling rate should also be controlled within a reasonable range to avoid cracks or deformation of the ceramic piece due to thermal expansion and contraction.

[0052] 5. Subsequent Processing

[0053] Quality Inspection: Finally, the fired ceramic snow-glazed piece is subjected to quality inspection to ensure that it meets the expected snow mountain effect and other performance requirements.
