Whether you need standard models or fully customized solutions, KINGSTAR provides the expertise, consistency, and reliability required for international markets.

The superior choice for modern storage. As a premier supplier of advanced glassware, KINGSTAR GLASSWARE presents our extensive collection of High Borosilicate Glass Jars. This is not ordinary glass. Borosilicate glass is a high-performance material prized for its remarkable combination of being lightweight, exceptionally clear, and highly resistant to thermal shock. This makes it the ultimate material for a versatile, safe, and beautiful storage system, ideal for the modern kitchen, pantry, and beyond. It's the top choice for retailers and brands targeting the premium kitchenware and health-conscious consumer markets.

What are the main advantages of High Borosilicate Glass over standard glass?

This is the key question, and the advantages are significant:

1. Thermal Shock Resistance: It can handle rapid temperature changes without cracking. This means you can safely wash a jar in hot water or even use it in a microwave (without metal lids).

2. Lightweight & Strong: It has a higher strength-to-weight ratio, allowing for thinner, more elegant, yet durable designs.

3. Superior Clarity: It has a brilliant, crystal-like clarity that doesn't have the slight green tint of standard soda-lime glass.

4. Chemical Resistance: It is highly resistant to chemicals and is non-porous, ensuring it will never absorb odors or flavors.

How do you ensure a quality airtight seal across your range of lids?

A great jar needs a great lid. We pair our high-quality borosilicate jars with a variety of premium lids, most of which feature a food-grade silicone gasket. This gasket creates a firm, reliable airtight seal that locks out air and moisture, crucial for preserving the freshness of everything from coffee beans to crunchy cookies. As an experienced manufacturer, we ensure the fit and finish of both the jar and lid are perfect.

What is your MOQ for this product line and can you create custom sets?

We are structured to be a flexible factory partner for our clients. For our high borosilicate glass jars, the Minimum Order Quantity (MOQ) typically starts around 2,000 to 5,000 units per size. Our core strength lies in creating custom retail-ready sets. We can work with you to curate a collection of different sizes (e.g., a "Coffee & Tea Station" set or a "Pantry Makeover" kit), package them in a beautiful branded box, and create a high-value product for your customers.

Choosing KINGSTAR GLASSWARE means sourcing a technologically superior storage solution from a supplier who leads in quality and innovation.

FAQ

Q1: What makes a high borosilicate glass jar better than a regular glass jar for food storage?

High borosilicate glass jars are made with a specialty glass that contains boron oxide, giving them exceptional thermal shock resistance and chemical stability compared with ordinary soda‑lime glass. This means they can safely handle rapid temperature changes — such as going from freezer to oven or microwave — without cracking, and the inert material won’t react with food or absorb odors. These properties make them ideal for preserving a wide range of food products, from dry goods and spices to acidic foods like sauces.

Q2: Are high borosilicate glass jars safe for everyday kitchen use, including heating and freezing?

Yes, high borosilicate glass jars are food‑safe and designed for everyday kitchen use. Their low thermal expansion coefficient allows them to withstand significant temperature differences without breaking, so they are suitable for freezer, refrigerator, microwave, dishwasher, and some oven applications when the lid is removed (always check lid material limits). The non‑porous surface also resists stains and odor buildup, simplifying cleaning and maintaining hygiene.

Q3: How should I care for and maintain my high borosilicate glass jar to ensure long‑lasting performance?

To maximize durability and performance, clean high borosilicate glass jars with warm water and mild detergent, and avoid drastic temperature shock (e.g., removing a frozen jar directly into very hot water). Although the glass itself is highly heat resistant, any bamboo, wood, or non‑glass lid components should be removed before heating. Most high borosilicate jars are dishwasher‑safe, but gentle hand washing of lids and seals helps preserve airtight performance.
