Multicolor Grape Pattern Glass Candle Jars

Multicolor Grape Pattern Glass Candle Jars for Premium Home Décor and Artisan Candle Branding

Xuzhou Muzhishi Crafts Co., Ltd. brings over 20 years of manufacturing excellence to the decorative glass industry with our Multicolor Grape Pattern Glass Candle Jars. These cases are made of high-clarity soda-lime glass and have gradient colour finishes and intricately engraved grape designs. Each jar goes through several stages of annealing to make it resistant to thermal shock up to 150°C. This keeps the structure strong during long burn cycles. Each of our 10 specialised glass kilns can make up to 1 million units per day, with the help of 6 automatic lines per furnace. We can make moulds and print 3D models in-house, so we can send unique tests in 3–5 days and mass production in about 30 days.

What Makes These Glass Vessels Ideal for Candle Applications

The unique shape of these jars solves problems that candle makers and home decor brands often have. The raised grape bunches on the outside give the design depth while keeping the inside smooth. This smooth inner wall makes sure that the wax sticks evenly and stops the "wet spot" problem that makes the product look bad.

Candle containers must be able to withstand changes in temperature. The coefficient of thermal expansion of these jars stays the same from 0°C to 150°C. A wall thickness consistency of ±0.5mm gets rid of hot spots that make the fire burn unevenly. The mass of glass, which is between 2.4 and 2.5 g/cm³, gives it the weight it needs to be stable while still being clear.

High-fire vapour deposition or organic spray coating are used to make the multicolour finish. These ways make colours that are bright and won't lose much of their colour after up to 50 runs in an industrial dishwasher. Organic coatings contain UV inhibitors that keep colours from fading when they are shown in direct sunlight or stores.

Multicolor Grape Pattern Glass Candle Jars Specifications

Quality Assurance Through Rigorous Testing

To meet international standards, each batch goes through a series of thorough inspections. As per ASTM C149, the thermal shock test takes jars from 100°C to 20°C water settings to see if they can't break. This makes sure that your candles can handle changes in temperature while they are being shipped and while people are using them.

During annealing grade checks, a polariscope is used to look for any remaining internal stress that could weaken the material's longevity. The ASTM D3359 cross-hatch tape method is used for coating adhesion testing, which shows that multicolour finishes stay intact after being exposed to heat for a long time.

Measurements of verticality and lip flatness make sure that the lid fits tightly and can be used with automatic wax-pouring equipment. ICP-OES tests for lead and cadmium leaching make sure that California Prop 65 and REACH rules are followed. These quality checks keep your customers safe and protect the image of your brand.

Design Features That Enhance Candle Performance

The design of grapes is placed on the outside in a smart way. This design choice keeps the inside smooth so that wax can stick better while adding depth to the look. The depth of the embossing is set so that it catches light without casting shadows that make it hard to see the flame.

High refractive index properties make the flame brighter, giving off a warm glow. The non-porous glass surface stops fragrance oil from moving around and seeping, so the scent stays strong for as long as the candle lasts. Light can break down delicate scent molecules, but UV protecting qualities keep them from breaking down.

We provide thermal mapping data to help you select appropriate wick sizes for each Multicolor Grape Pattern Glass Candle Jars diameter. This technical support prevents tunneling and ensures full melt pool formation across the entire surface. Proper wick pairing maximizes burn time and customer satisfaction.

Frequently Asked Questions

Q: Does the multicolor coating affect wax adhesion?

A: No. We utilize internal masking during the spray process to ensure the interior remains raw glass, preventing adhesion failure or "wet spots."

Q: Can these jars withstand industrial dishwasher temperatures for recycling?

A: Yes. Our high-fire vapor deposition colors are rated for up to 50 commercial wash cycles without significant tint loss.

Q: Is the grape pattern embossed on the inside or outside?

A: The pattern is always external to ensure a smooth interior for even wax burns and easy cleaning.

Q: How do you prevent tunneling with such a textured shape?

A: We provide thermal mapping data to help you select the correct wick size for the specific jar diameter to ensure a full melt pool.

Q: Are the pigments UV-stable?

A: We incorporate UV inhibitors in our organic coatings to prevent color fading when jars are displayed in direct sunlight or retail windows.
