1. Classification of Glass Bottles

There are many types of glass bottles depending on their use, color, shape, and neck design. Below are the main categories used in the market.

1.1 Classification by Use

• Wine Bottles – The most common type of glass bottles, often round in shape, used for red wine, white wine, and champagne.
• Daily Use Bottles – Used for cosmetics, essential oils, glue, or ink. Their designs and closures vary widely depending on the product.
• Cans and Jars – Typically wide-mouth bottles (0.2–0.5L capacity) for canned foods and sauces.
• Medicine Bottles – Include 10–200ml brown vials, 100–1000ml infusion bottles, and sealed ampoules for medical use.
• Chemical Reagent Bottles – Designed for laboratory use with 250–1200ml capacity, usually screw or ground neck.

1.2 Classification by Color

Glass bottles come in different colors, including clear (flint), amber (brown), green, blue, and frosted glass.
Each color provides unique protection levels against UV light and serves different aesthetic purposes for branding.

1.3 Classification by Bottle Neck

• Long-neck bottles
• Short-neck bottles
• Thick-neck and thin-neck bottles
• Neckless bottles

Neck style affects both appearance and sealing performance.

1.4 Classification by Mouth Size

• Small-mouth bottles – Inner diameter under 20mm, often used for beverages such as beer or soda.
• Large-mouth bottles – 20–30mm, ideal for milk or juices.
• Wide-mouth bottles – Over 30mm, commonly used for canned foods or viscous products.

1.5 Classification by Shape

• Round Bottles – Most durable and widely used.
• Square Bottles – Stylish but harder to manufacture.
• Curved Bottles – Include unique designs like gourd or flower-shaped bottles.
• Oval Bottles – Compact and elegant, often used for perfumes or premium spirits.

2. How Glass Bottles Are Manufactured

High-quality glass liquor bottle manufacturers follow strict production steps to ensure clarity, durability, and consistency. The main stages include:

2.1 Raw Material Preparation

Key ingredients like quartz sand, soda ash, limestone, and feldspar are crushed, dried, and refined to remove impurities such as iron.

2.2 Batch Mixing

The raw materials are measured and mixed evenly to prepare for melting.

2.3 Melting

The batch is heated to 1550–1600°C in a furnace until it becomes a uniform, bubble-free molten glass.

2.4 Forming

Molten glass is blown or pressed into molds to create bottles of various shapes and sizes.

2.5 Heat Treatment

Annealing and cooling remove internal stress, strengthen the glass, and ensure structural stability.

4. How to Identify High-Quality Glass Bottles

When selecting a liquor glass bottle supplier, you can judge quality from several key indicators:

4.1 Sound Test

Tap the bottle gently — high-quality crystal glass produces a clear, ringing sound, while ordinary glass sounds dull.

4.2 Weight

Crystal bottles are heavier than normal glass ones of the same volume.

4.3 Refraction

Under light, crystal bottles have a higher refractive index and display rainbow-like colors, while regular glass does not.

4.4 Hardness

Crystal is harder than glass. Scratching glass with crystal leaves a mark, but not vice versa.

These methods, combined with checking the manufacturer’s quality standards, can help ensure you buy premium bottles suitable for your brand.
