The production and processing of silk screen colored glaze glass is a complex and meticulous process. The following are its main production steps:

1. Preliminary preparation

Material selection: Choose high-quality glass materials with good light transmittance according to the usage requirements of silk screen colored glaze glass. This is the first step in producing silk screen colored glaze glass, ensuring the quality of the base materials is crucial for subsequent processing and product quality.

Cutting and cleaning: Cut the glass into the required shapes and sizes according to design requirements and dimensions, and thoroughly clean it to remove surface dirt and impurities.

Glaze material selection and mixing: Select high-quality lead-free, non-toxic glaze materials, and accurately weigh the materials according to the formula based on the color and pattern requirements of silk screen colored glaze glass for mixing. The choice and mixing of glaze materials directly affect the color and pattern effects of the final product.

2. Base layer glazing

Glazing method: Use dipping or spraying methods to evenly apply base layer glaze material on the surface of the glass. This step provides a good foundation for subsequent surface glazing.

3. Surface glazing and silk screening

Silk screening process: Use a silk screen printing plate with glass glaze material to perform surface glazing on top of the base layer glaze, forming various patterns and colors. Silk screen printing features clear patterns and bright colors, suitable for mass production.

Other printing processes: In addition to silk screen printing, roller printing, spraying printing, etc., can also be used for surface glazing. These processes each have their characteristics and can be selected based on actual needs.

4. Drying and sintering

Drying: Printed glass products need to undergo drying treatment to remove moisture and solvents from the glaze material. The drying temperature and speed are usually adjusted based on factors such as glass thickness, size, glaze layer thickness, coverage rate, etc.

Sintering: Place dried glass products in a furnace for sintering treatment. During sintering, the glaze material melts and firmly adheres to the surface of the glass, forming a strong colored glaze layer. The choice of sintering temperature and time should be determined based on the type of glaze material used and furnace type.

5. Post-processing and inspection

Cooling: After sintering is complete, it is necessary to place glass products in a cooling furnace for cooling treatment. The cooling process also needs precise control to avoid excessive temperature differences that could cause glass breakage or glaze material peeling off.

Surface treatment: Perform polishing, sanding, sandblasting, etc., on colored glazed glass as needed to improve its appearance quality and tactile feel.

Processing and customization: Carry out cutting, edge grinding, drilling processing on colored glazed glass to meet actual application needs. At the same time, customized processing can also be done according to customer’s personalized requirements.

Inspection: Throughout the production process, strict quality inspections need to be conducted at every stage. Inspection content includes but is not limited to appearance quality, pattern clarity, color uniformity, wear resistance, corrosion resistance etc. Only those colored glazed glass products that pass strict inspections can be sold out of factory.

6. Packaging and storage

Packaging: Properly package inspected qualified silk screen colored glazed glass products to protect them from damage during transportation and storage.

'Storage: Store packaged silk screen colored glazed glasses in a dry, ventilated environment away from light to prevent moisture damage or fading.'
