Production Process & Quality Control for the 750ml Super Flint Napoleon Glass Liquor Bottle

🔹 1. Premium Material Selection

The production of this luxury 750ml Napoleon-style glass liquor bottle begins with the careful selection of high-grade raw materials, including:

• Silica sand (SiO₂) – ensuring clarity and purity
• Soda ash, limestone, and dolomite – to provide chemical stability and durability
• Super Flint cullet – recycled high-clarity glass that enhances brilliance and reduces energy use

The combination of these materials produces super flint (extra-clear) glass, known for its crystal-like transparency and brilliance – ideal for premium liquor presentation.

🔹 2. Melting & Refining

• The raw materials are melted in an automated furnace at temperatures exceeding 1400°C (2552°F).
• A continuous melting process ensures the glass is homogeneous and free from impurities.
• The molten glass is then passed through a refining zone to remove air bubbles and achieve optical clarity.

---

🔹 3. Precision Forming Process

• Using an advanced IS (Individual Section) machine, the molten glass is formed into bottles via the blow-and-blow or press-and-blow method.
• The Napoleon round shape is achieved through customized molds designed to exact dimensions for balance, elegance, and compatibility with corks or caps.
• Each bottle is formed to precise standards for uniform wall thickness, smooth neck finish, and consistent weight (approx. 750g).

🔹 4. Controlled Annealing

• Once formed, bottles enter a lehr (annealing oven) where they are gradually cooled from approx. 550°C to room temperature.
• This stress-relief process improves structural integrity and prevents cracking or internal weakness.

🔹 5. Surface Treatment & Optional Decoration

To enhance functionality and brand appeal, the bottle can undergo various finishing treatments:

• Silk screen printing for logos or labels
• Frosting / Acid etching for a matte texture
• Spray painting or electroplating for color or metallic effects
• Decals or hot stamping for branding or limited edition designs

---

🔹 6. Strict Quality Control & Inspection

Quality assurance is implemented at every stage:

• Automated vision inspection systems detect bubbles, cracks, dimensional variance, and surface defects
• Manual inspections verify finish quality, bottle mouth precision (for proper cork/cap fitting), and clarity
• Dimensional tests ensure cork or cap compatibility with tight tolerance

Each batch is subjected to:

• Thermal shock resistance tests
• Pressure resistance tests
• Drop tests to simulate transport conditions

---

🔹 7. Packaging & Protection

• Bottles are packed in 5-layer reinforced export cartons with dividers or trays to prevent collision.
• Optional palletized packaging is available for bulk orders.
• Packaging can be customized to meet branding or retail display needs.
