750ml Antique Green Dorica Phoenix Oil Glass Bottle

1. Raw material preparation
Silica sand (SiO2): It is the main component of glass and provides the basic structure of glass.
Sodium carbonate (Na2CO3): As a flux, it lowers the melting point of silica sand.
Calcium carbonate (CaCO3): Stabilizer, improves the chemical stability and mechanical strength of glass.
Magnesium oxide (MgO), aluminum oxide (Al2O3): Used to improve the heat resistance and mechanical properties of glass.
Colorants: Such as iron oxide, chromium oxide, etc., are used to make olive green glass.
2. Mixing raw materials
The above raw materials are mixed evenly in a certain proportion to form a glass batch.
3. Melting
The batch is fed into a high-temperature furnace and heated to about 1600°C until the raw materials are completely melted into liquid glass.
4. Molding
Blow-Blow Process:
The molten glass is fed into the mold through a feeder to form the preliminary shape of the bottle.
The first blow causes the glass to form a bottle embryo in the mold.
The second blow further expands the bottle embryo to form the final bottle shape.
Press-Blow Process:
First, the bottle embryo is formed by pressing, and then blow molding is performed.
5. Annealing
The formed glass bottle needs to pass through the annealing furnace and slowly cool down to eliminate internal stress and prevent the bottle from breaking in subsequent use.
6. Cooling
After the bottle comes out of the annealing furnace, it continues to cool to room temperature at room temperature.
7. Cutting and grinding
Remove the burrs on the bottle mouth and bottom, and grind the bottle body to make it smooth and flat.
8. Engraving or printing
Engrave patterns or print on the bottle body. This step may use engraving, screen printing, hot stamping, and other technologies.
9. Inspection
The bottle is inspected for appearance, size, weight, pressure resistance, and other qualities.
10. Packaging
The qualified products are cleaned, then packaged and prepared for shipment.
The entire manufacturing process requires precise control of multiple factors such as temperature, time, and pressure to ensure the quality and beauty of the glass bottle. The unique color and pattern of the olive green Phoenix oil glass bottle require higher standards and more sophisticated operations in raw material selection and manufacturing process.
